# Provisioning Application Examples
|
||||
|
||||
These consist of the following examples :
|
||||
|
||||
* softap_prov
|
||||
Provisioning involves Wi-Fi station configuration via an HTTP server running on the device, which is initially configured to be in SoftAP mode. After provisioning, device runs in Wi-Fi station mode only and connects to the AP whose credentials were provided during provisioning.
|
||||
|
||||
* ble_prov
|
||||
Provisioning involves Wi-Fi station configuration via BLE service endpoints running on the device initially. After provisioning, BLE is turned off and device runs in Wi-Fi station mode, connecting to the AP whose credentials were provided during provisioning.
|
||||
|
||||
* console_prov
|
||||
Provisioning involves Wi-Fi station configuration via UART console. This is intended for debugging protocomm and provisioning related features.
|
||||
|
||||
* custom_config
|
||||
Similar to softap_prov examples, but allows for configuration of custom (device-local) information during provisioning. This is intended as an example for implementing custom provisioning schemes.
|
||||
|
||||
Provisioning applications are available for various platforms:
|
||||
|
||||
* For Android, a provisioning application along with source code is available on GitHub : [esp-idf-provisioning-android](https://github.com/espressif/esp-idf-provisioning-android)
|
||||
* For iOS, a provisioning application along with source code is available on GitHub : [esp-idf-provisioning-ios](https://github.com/espressif/esp-idf-provisioning-ios)
|
||||
* For all other platforms a python based command line tool is provided under "$IDF_PATH/tools/esp_prov"
|
||||
|
||||
Refer to the README.md files in each example directory for more information.

# BLE based Provisioning Example
|
||||
|
||||
(See the README.md file in the upper level 'examples' directory for more information about examples.)
|
||||
|
||||
`ble_prov` example demonstrates the implementation and integration of various IDF components for building a provisioning application.
|
||||
|
||||
For this example BLE is chosen as the mode of transport, over which the provisioning related communication is to take place, between the device (to be provisioned) and the client (owner of the device).
|
||||
|
||||
In the provisioning process the device is configured as a Wi-Fi station with specified credentials. Once configured, the device will retain the Wi-Fi configuration, until a flash erase is performed.
|
||||
|
||||
Right after provisioning is complete, BLE is turned off and disabled to free the memory used by the BLE stack. Though, that is specific to this example, and the user can choose to keep BLE on in their own application.
|
||||
|
||||
`ble_prov` uses the following components :
|
||||
* `wifi_provisioning` : provides data structures and protocomm endpoint handlers for Wi-Fi configuration
|
||||
* `protocomm` : for protocol based communication and secure session establishment
|
||||
* `protobuf` : Google's protocol buffer library for serialization of protocomm data structures
|
||||
* `bt` : ESP32 BLE stack for transport of protobuf packets
|
||||
|
||||
This example can be used, as it is, for adding a provisioning service to any application intended for IoT.
|
||||
|
||||
## How to use example
|
||||
|
||||
### Hardware Required
|
||||
|
||||
Example should be able to run on any commonly available ESP32 development board.
|
||||
|
||||
### Application Required
|
||||
|
||||
Provisioning applications are available for various platforms. See below
|
||||
|
||||
#### Platform : Android
|
||||
|
||||
For Android, a provisioning application along with source code is available on GitHub : [esp-idf-provisioning-android](https://github.com/espressif/esp-idf-provisioning-android)
|
||||
|
||||
#### Platform : iOS
|
||||
|
||||
For iOS, a provisioning application along with source code is available on GitHub : [esp-idf-provisioning-ios](https://github.com/espressif/esp-idf-provisioning-ios)
|
||||
|
||||
#### Platform : Linux / Windows / macOS
|
||||
|
||||
To provision the device running this example, the `esp_prov.py` script needs to be run (found under `$IDF_PATH/tools/esp_prov`). Make sure to satisfy all the dependencies prior to running the script.
|
||||
|
||||
Presently, `esp_prov` supports BLE transport only for Linux platform. For Windows/macOS it falls back to console mode and requires another application (for BLE) through which the communication can take place.
|
||||
|
||||
There are various applications, specific to Windows and macOS platform which can be used. The `esp_prov` console will guide you through the provisioning process of locating the correct BLE GATT services and characteristics, the values to write, and input read values.
|
||||
|
||||
### Configure the project
|
||||
|
||||
```
|
||||
make menuconfig
|
||||
```
|
||||
|
||||
* Set serial port under Serial Flasher Options.
|
||||
|
||||
* Under Example Configuration set the following :
|
||||
* Security Version (default 1)
|
||||
* Proof of Possession (default "abcd1234")
|
||||
|
||||
### Build and Flash
|
||||
|
||||
Build the project and flash it to the board, then run monitor tool to view serial output:
|
||||
|
||||
```
|
||||
make -j4 flash monitor
|
||||
```
|
||||
|
||||
(To exit the serial monitor, type ``Ctrl-]``.)
|
||||
|
||||
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
|
||||
|
||||
## Example Output
|
||||
|
||||
```
|
||||
I (550) app: Starting BLE provisioning
|
||||
I (1130) app_prov: Provisioning started with BLE devname : PROV_261FCC
|
||||
```
|
||||
|
||||
Make sure to note down the BLE device name (starting with PROV_) displayed in the serial monitor log (eg. PROV_261FCC). This will depend on the MAC ID and will be unique for every device.
|
||||
|
||||
In a separate terminal run the `esp_prov.py` script under `$IDP_PATH/tools/esp_prov` directory (please replace `myssid` and `mypassword` with the credentials of the AP to which the device is supposed to connect to after provisioning). Assuming default example configuration :
|
||||
|
||||
```
|
||||
python esp_prov.py --ssid myssid --passphrase mypassword --sec_ver 1 --pop abcd1234 --transport ble --ble_devname PROV_261FCC
|
||||
```
|
||||
|
||||
Above command will perform the provisioning steps, and the monitor log should display something like this :
|
||||
|
||||
```
|
||||
I (682950) app_prov_handler: WiFi Credentials Received :
|
||||
ssid : myssid
|
||||
password : mypassword
|
||||
.
|
||||
.
|
||||
.
|
||||
I (683130) app_prov: STA Start
|
||||
I (683130) app_prov_handler: WiFi Credentials Applied
|
||||
.
|
||||
.
|
||||
.
|
||||
I (688270) app_prov_handler: Connecting state
|
||||
.
|
||||
.
|
||||
.
|
||||
I (688390) app_prov: STA Got IP
|
||||
I (688390) app: got ip:192.168.43.220
|
||||
I (693410) app_prov_handler: Connected state
|
||||
```
|
||||
|
||||
After sometime the provisioning app will exit and BLE will be turned off
|
||||
|
||||
```
|
||||
I (718390) app_prov: Stopping provisioning
|
||||
I (718670) app_prov: Provisioning stopped
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Provisioning failed
|
||||
|
||||
It is possible that the Wi-Fi credentials provided were incorrect, or the device was not able to establish connection to the network, in which the the `esp_prov` script will notify failure (with reason) and the provisioning app will continue running, allowing the user to retry the process. Serial monitor log will display the failure along with disconnect reason :
|
||||
|
||||
```
|
||||
E (39291) app_prov: STA Disconnected
|
||||
E (39291) app_prov: Disconnect reason : 201
|
||||
I (39291) app_prov: STA AP Not found
|
||||
I (42021) app_prov_handler: Disconnected state
|
||||
```
|
||||
|
||||
### Provisioning does not start
|
||||
|
||||
If the serial monitor log is different, as shown below :
|
||||
|
||||
```
|
||||
I (539) app_prov: Found ssid myssid
|
||||
I (539) app_prov: Found password mypassword
|
||||
I (549) app: Starting WiFi station
|
||||
```
|
||||
|
||||
It means the Wi-Fi credentials were already set by some other application flashed previously to your device. To erase these credentials either do full erase and then flash the example
|
||||
|
||||
```
|
||||
make erase_flash
|
||||
make -j4 flash monitor
|
||||
```
|
||||
|
||||
Or, enable `Reset Provisioning` option under `Example Configuration` under menuconfig. But this will erase the saved Wi-Fi credentials every time the device boots, so this is not the preferred solution.
|
||||
|
||||
### Unsupported platform
|
||||
|
||||
If the platform requirement, for running `esp_prov` is not satisfied, then the script execution will fallback to console mode, in which case the full process (involving user inputs) will look like this :
|
||||
|
||||
```
|
||||

||||

# Console based Provisioning Example
|
||||
|
||||
(See the README.md file in the upper level 'examples' directory for more information about examples.)
|
||||
|
||||
`console_prov` example demonstrates the implementation and integration of various IDF components for building a console based provisioning application.
|
||||
|
||||
For this example UART console is chosen as the mode of transport, over which the provisioning related communication is to take place, between the device (to be provisioned) and the client (owner of the device).
|
||||
|
||||
In the provisioning process the device is configured as a Wi-Fi station with specified credentials. Once configured, the device will retain the Wi-Fi configuration, until a flash erase is performed.
|
||||
|
||||
Right after provisioning is complete, the UART console is deactivated.
|
||||
|
||||
`console_prov` uses the following components :
|
||||
* `wifi_provisioning` : provides data structures and protocomm endpoint handlers for Wi-Fi configuration
|
||||
* `protocomm` : for protocol based communication and secure session establishment
|
||||
* `protobuf` : Google's protocol buffer library for serialization of protocomm data structures
|
||||
|
||||
This example can be used, as it is, for adding a provisioning service to any application intended for IoT. But it is more suitable for debugging protocomm and provisioning related components and feature additions.
|
||||
|
||||
## How to use example
|
||||
|
||||
### Hardware Required
|
||||
|
||||
Example should be able to run on any commonly available ESP32 development board.
|
||||
|
||||
### Application Required
|
||||
|
||||
To provision the device running this example, the `esp_prov.py` script needs to be run (found under `$IDF_PATH/tools/esp_prov`). This feature of `esp_prov` should work on all platforms, given the dependencies are satisfied.
|
||||
|
||||
### Configure the project
|
||||
|
||||
```
|
||||
make menuconfig
|
||||
```
|
||||
|
||||
* Set serial port under Serial Flasher Options.
|
||||
|
||||
* Under Example Configuration set the following :
|
||||
* Security Version (default 1)
|
||||
* Proof of Possession (default "abcd1234")
|
||||
|
||||
### Build and Flash
|
||||
|
||||
Build the project and flash it to the board, then run monitor tool to view serial output:
|
||||
|
||||
```
|
||||
make -j4 flash monitor
|
||||
```
|
||||
|
||||
(To exit the serial monitor, type ``Ctrl-]``.)
|
||||
|
||||
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
|
||||
|
||||
## Example Output
|
||||
|
||||
```
|
||||
I (388) app: Starting console provisioning
|
||||
I (398) app_prov: Console provisioning started
|
||||
.
|
||||
.
|
||||
.
|
||||
>>
|
||||
```
|
||||
|
||||
In a separate terminal run the `esp_prov.py` script under `$IDP_PATH/tools/esp_prov` directory (please replace `myssid` and `mypassword` with the credentials of the AP to which the device is supposed to connect to after provisioning). Assuming default example configuration, the script should be run as follows :
|
||||
|
||||
```
|
||||
python esp_prov.py --ssid myssid --passphrase mypassword --sec_ver 1 --pop abcd1234 --transport console
|
||||
```
|
||||
|
||||
A console will open up and the `Client->Device` commands have to be copied manually to the serial monitor console prompt :
|
||||
|
||||
```
|
||||
==== Esp_Prov Version: V0.1 ====
|
||||
|
||||
==== Verifying protocol version ====
|
||||
Client->Device msg : proto-ver 0 56302e31
|
||||
Enter device->client msg :
|
||||
```
|
||||
|
||||
On pasting the command on the serial monitor console, a `Device->Client` message will appear for each command :
|
||||
|
||||
```
|
||||
>> proto-ver 0 56302e31
|
||||
53554343455353
|
||||
```
|
||||
|
||||
Copy this message back to the `esp_prov` console for proceeding to the next command :
|
||||
|
||||
```
|
||||
==== Verifying protocol version ====
|
||||
Client->Device msg : proto-ver 0 56302e31
|
||||
Enter device->client msg : 53554343455353
|
||||
==== Verified protocol version successfully ====
|
||||
|
||||
==== Starting Session ====
|
||||
Client->Device msg : prov-session 0 10015a25a201220a20677106cc2f5b2acb5d8da26f0ad443df006daa1cd5bb3d75a8324d81ec5ef970
|
||||
Enter device->client msg :
|
||||
```
|
||||
|
||||
This process keeps on till the device gets provisioned.
|
||||
|
||||
Note that the commands are in the following format :
|
||||
|
||||
```
|
||||
<endpoint name> <session id> <hex message>
|
||||
```
|
||||
|
||||
This is helpful in understanding the provisioning process and the order in which the endpoints are communicated with.
|
||||
|
||||
The full execution sequence of `esp_prov`, as seen on the console, is shown here :
|
||||
|
||||

|

```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Provisioning failed
|
||||
|
||||
It is possible that the Wi-Fi credentials provided were incorrect, or the device was not able to establish connection to the network, in which the the `esp_prov` script will notify failure (with reason) and the provisioning app will continue running, allowing the user to retry the process. Serial monitor log will display the failure along with disconnect reason :
|
||||
|
||||
```
|
||||
E (39291) app_prov: STA Disconnected
|
||||
E (39291) app_prov: Disconnect reason : 201
|
||||
I (39291) app_prov: STA AP Not found
|
||||
I (42021) app_prov_handler: Disconnected state
|
||||
```
|
||||
|
||||
### Provisioning does not start
|
||||
|
||||
If the serial monitor log is different, as shown below :
|
||||
|
||||
```
|
||||
I (539) app_prov: Found ssid myssid
|
||||
I (539) app_prov: Found password mypassword
|
||||
I (549) app: Starting WiFi station
|
||||
```
|
||||
|
||||
It means the Wi-Fi credentials were already set by some other application flashed previously to your device. To erase these credentials either do full erase and then flash the example
|
||||
|
||||
```
|
||||
make erase_flash
|
||||
make -j4 flash monitor
|
||||
```
|
||||
|
||||
Or, enable `Reset Provisioning` option under `Example Configuration` under menuconfig. But this will erase the saved Wi-Fi credentials every time the device boots, so this is not the preferred solution.

# SoftAP + HTTPD based Provisioning Example featuring Custom configuration
|
||||
|
||||
(See the README.md file in the upper level 'examples' directory for more information about examples.)
|
||||
|
||||
(Please see the README.md under `softap_prov` example before this.)
|
||||
|
||||
`custom_config` example demonstrates the implementation and integration of various IDF components for building a provisioning application.
|
||||
|
||||
This is same as `softap_prov` example, with added feature for configuration of some custom data (just like Wi-Fi configuration) during provisioning. The custom data provided during provisioning is simply printed on the serial monitor. The rest of the program functions just like `softap_prov`, ie. the device is configured as Wi-Fi station with supplied AP credentials.
|
||||
|
||||
|
||||
`custom_config` uses the following components :
|
||||
* `wifi_provisioning` : provides data structures and protocomm endpoint handlers for Wi-Fi configuration
|
||||
* `protocomm` : for protocol based communication and secure session establishment
|
||||
* `protobuf` : Google's protocol buffer library for serialization of protocomm data structures
|
||||
|
||||
Also, it uses a component provided with this example `custom_provisioning` which provides data structures and protocomm endpoint handlers for custom data configuration
|
||||
|
||||
## How to use example
|
||||
|
||||
### Hardware Required
|
||||
|
||||
Example should be able to run on any commonly available ESP32 development board.
|
||||
|
||||
### Application Required
|
||||
|
||||
To provision the device running this example, the `esp_prov.py` script needs to be run (found under `$IDF_PATH/tools/esp_prov`). This feature of `esp_prov` should work on all platforms, given the dependencies are satisfied.
|
||||
|
||||
### Configure the project
|
||||
|
||||
```
|
||||
make menuconfig
|
||||
```
|
||||
|
||||
* Set serial port under Serial Flasher Options.
|
||||
|
||||
* Under Example Configuration set the following :
|
||||
* SoftAP SSID (Defaults to PROV_<MACID>)
|
||||
* SoftAP Password (Defaults to PROV_PASS)
|
||||
* Security Version (default 0)
|
||||
* Proof of Possession (by default not needed for security version 0)
|
||||
|
||||
### Build and Flash
|
||||
|
||||
Build the project and flash it to the board, then run monitor tool to view serial output:
|
||||
|
||||
```
|
||||
make -j4 flash monitor
|
||||
```
|
||||
|
||||
(To exit the serial monitor, type ``Ctrl-]``.)
|
||||
|
||||
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
|
||||
|
||||
## Example Output
|
||||
|
||||
```
|
||||
I (1562) app: SoftAP started
|
||||
I (1572) app_prov: SoftAP Provisioning started with SSID 'PROV_261FCC', Password 'PROV_PASS'
|
||||
```
|
||||
|
||||
Make sure to connect the client computer to the SoftAP network, whose SSID and Password are displayed in the serial monitor log. On successful connection the monitor log will show :
|
||||
|
||||
```
|
||||
I (519482) tcpip_adapter: softAP assign IP to station,IP is: 192.168.4.2
|
||||
```
|
||||
|
||||
In a separate terminal run the `esp_prov.py` script under `$IDP_PATH/tools/esp_prov` directory (please replace the values corresponding to the parameters `--custom_info` and `--custom_ver` with your desired values for the custom configuration). Assuming default example configuration, the script should be run as follows :
|
||||
|
||||
```
|
||||
python esp_prov.py --ssid myssid --passphrase mypassword --sec_ver 0 --transport softap --softap_endpoint 192.168.4.1:80 --custom_config --custom_info "some string" --custom_ver 4321
|
||||
```
|
||||
|
||||
Above command will perform the provisioning steps, and the monitor log should display something like this :
|
||||
|
||||
```
|
||||
I (92734) app_prov_handler: Custom config received :
|
||||

|
||||
I (654562) app_prov_handler: Connected state
|
||||
```
|
||||
|
||||
After sometime the provisioning app will exit, SoftAP will be turned off and HTTP server will be stopped
|
||||
|
||||
```
|
||||
I (667732) app_prov: Stopping provisioning
|
||||
I (668732) app_prov: Provisioning stopped
|
||||
I (668742) app: SoftAP stopped
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Provisioning failed
|
||||
|
||||
It is possible that the Wi-Fi credentials provided were incorrect, or the device was not able to establish connection to the network, in which the the `esp_prov` script will notify failure (with reason) and the provisioning app will continue running, allowing the user to retry the process. Serial monitor log will display the failure along with disconnect reason :
|
||||
|
||||
```
|
||||
E (39291) app_prov: STA Disconnected
|
||||
E (39291) app_prov: Disconnect reason : 201
|
||||
I (39291) app_prov: STA AP Not found
|
||||
I (42021) app_prov_handler: Disconnected state
|
||||
```
|
||||
|
||||
### Provisioning does not start
|
||||
|
||||
If the serial monitor log is different, as shown below :
|
||||
|
||||
```
|
||||
I (539) app_prov: Found ssid myssid
|
||||
I (539) app_prov: Found password mypassword
|
||||
I (549) app: Starting WiFi station
|
||||
```
|
||||
|
||||
It means the Wi-Fi credentials were already set by some other application flashed previously to your device. To erase these credentials either do full erase and then flash the example
|
||||
|
||||
```
|
||||
make erase_flash
|
||||
make -j4 flash monitor
|
||||
```
|
||||
|
||||
Or, enable `Reset Provisioning` option under `Example Configuration` under menuconfig. But this will erase the saved Wi-Fi credentials every time the device boots, so this is not the preferred solution.

# Protobuf files for defining custom config-data packet structures
|
||||
|
||||
This is an example proto file defining custom configuration related data packet structures, namely -
|
||||
1. CustomConfigRequest - for sending configuration data consisting of various fields (Info and Version)
|
||||
2. CustomConfigResponse - for receiving configuration status (fail/success)
|
||||
|
||||
Note : These proto files are not automatically compiled during the build process.
|
||||
|
||||
Run "make" (Optional) to generate the respective C and Python files. The generated C files are used by protocomm itself to create, delete and manipulate transaction packets. The generated Python files can be used by python based applications for implementing client side interface to protocomm layer.
|
||||
|
||||
Compilation requires protoc (Protobuf Compiler) and protoc-c (Protobuf C Compiler) installed. Since the generated files are to remain the same, as long as the proto files are not modified, therefore the generated files are already available under "protocomm/proto-c" and "protocomm/python" directories, and thus running make (and installing the Protobuf compilers) is optional.

# SoftAP + HTTPD based Provisioning Example
|
||||
|
||||
(See the README.md file in the upper level 'examples' directory for more information about examples.)
|
||||
|
||||
`softap_prov` example demonstrates the implementation and integration of various IDF components for building a provisioning application.
|
||||
|
||||
For this example Wi-Fi SoftAP is chosen as the mode of transport, over which the provisioning related communication is to take place, between the device (to be provisioned) and the client (owner of the device). The provisioning service is hosted by an HTTP server which accepts requests to specific URIs corresponding to the available provisioning endpoints (eg. for session establishment, for Wi-Fi credentials configuration, etc.).
|
||||
|
||||
In the provisioning process the device is configured as a Wi-Fi station with specified credentials. Once configured, the device will retain the Wi-Fi configuration, until a flash erase is performed.
|
||||
|
||||
Right after provisioning is complete, Wi-Fi SoftAP and the HTTP server are deactivated. Though, that is specific to this example, and the user can choose to keep SoftAP / HTTP server active in their own application.
|
||||
|
||||
`softap_prov` uses the following components :
|
||||
* `wifi_provisioning` : provides data structures and protocomm endpoint handlers for Wi-Fi configuration
|
||||
* `protocomm` : for protocol based communication and secure session establishment
|
||||
* `protobuf` : Google's protocol buffer library for serialization of protocomm data structures
|
||||
|
||||
This example can be used, as it is, for adding a provisioning service to any application intended for IoT.
|
||||
|
||||
## How to use example
|
||||
|
||||
### Hardware Required
|
||||
|
||||
Example should be able to run on any commonly available ESP32 development board.
|
||||
|
||||
### Application Required
|
||||
|
||||
Provisioning applications are available for various platforms. See below
|
||||
|
||||
#### Platform : Android
|
||||
|
||||
For Android, a provisioning application along with source code is available on GitHub : [esp-idf-provisioning-android](https://github.com/espressif/esp-idf-provisioning-android)
|
||||
|
||||
#### Platform : iOS
|
||||
|
||||
For iOS, a provisioning application along with source code is available on GitHub : [esp-idf-provisioning-ios](https://github.com/espressif/esp-idf-provisioning-ios)
|
||||
|
||||
#### Platform : Linux / Windows / macOS
|
||||
|
||||
To provision the device running this example, the `esp_prov.py` script needs to be run (found under `$IDF_PATH/tools/esp_prov`). This feature of `esp_prov` should work on all platforms, given the dependencies are satisfied.
|
||||
|
||||
### Configure the project
|
||||
|
||||
```
|
||||
make menuconfig
|
||||
```
|
||||
|
||||
* Set serial port under Serial Flasher Options.
|
||||
|
||||
* Under Example Configuration set the following :
|
||||
* SoftAP SSID (Defaults to PROV_<MACID>)
|
||||
* SoftAP Password (Defaults to PROV_PASS)
|
||||
* Security Version (default 1)
|
||||
* Proof of Possession (default "abcd1234")
|
||||
|
||||
### Build and Flash
|
||||
|
||||
Build the project and flash it to the board, then run monitor tool to view serial output:
|
||||
|
||||
```
|
||||
make -j4 flash monitor
|
||||
```
|
||||
|
||||
(To exit the serial monitor, type ``Ctrl-]``.)
|
||||
|
||||
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
|
||||
|
||||
## Example Output
|
||||
|
||||
```
|
||||
I (1562) app: SoftAP started
|
||||
I (1572) app_prov: SoftAP Provisioning started with SSID 'PROV_261FCC', Password 'PROV_PASS'
|
||||
```
|
||||
|
||||
Make sure to connect the client computer to the SoftAP network, whose SSID and Password are displayed in the serial monitor log. On successful connection the monitor log will show :
|
||||
|
||||
```
|
||||
I (519482) tcpip_adapter: softAP assign IP to station,IP is: 192.168.4.2
|
||||
```
|
||||
|
||||
In a separate terminal run the `esp_prov.py` script under `$IDP_PATH/tools/esp_prov` directory (please replace `myssid` and `mypassword` with the credentials of the AP to which the device is supposed to connect to after provisioning). The SoftAP endpoint corresponds to the IP and port of the device on the SoftAP network, but this is usually same as the default value and may be left out. Assuming default example configuration, the script should be run as follows :
|
||||
|
||||
```
|
||||
python esp_prov.py --ssid myssid --passphrase mypassword --sec_ver 1 --pop abcd1234 --transport softap --softap_endpoint 192.168.4.1:80
|
||||
```
|
||||
|
||||
Above command will perform the provisioning steps, and the monitor log should display something like this :
|
||||
|
||||
```
|
||||
I (634572) app_prov_handler: WiFi Credentials Received :
|
||||
ssid : myssid
|
||||
password : mypassword
|
||||
.
|
||||
.
|
||||
.
|
||||
I (634652) app_prov_handler: WiFi Credentials Applied
|
||||
I (634652) app_prov: STA Start
|
||||
.
|
||||
.
|
||||
.
|
||||
I (688270) app_prov_handler: Connecting state
|
||||
.
|
||||
.
|
||||
.
|
||||
I (637732) app_prov: STA Got IP
|
||||
I (637732) app: got ip:192.168.43.220
|
||||
.
|
||||
.
|
||||
.
|
||||
I (654562) app_prov_handler: Connected state
|
||||
```
|
||||
|
||||
After sometime the provisioning app will exit, SoftAP will be turned off and HTTP server will be stopped
|
||||
|
||||
```
|
||||
I (667732) app_prov: Stopping provisioning
|
||||
I (668732) app_prov: Provisioning stopped
|
||||
I (668742) app: SoftAP stopped
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Provisioning failed
|
||||
|
||||
It is possible that the Wi-Fi credentials provided were incorrect, or the device was not able to establish connection to the network, in which the the `esp_prov` script will notify failure (with reason) and the provisioning app will continue running, allowing the user to retry the process. Serial monitor log will display the failure along with disconnect reason :
|
||||
|
||||
```
|
||||
E (39291) app_prov: STA Disconnected
|
||||
E (39291) app_prov: Disconnect reason : 201
|
||||
I (39291) app_prov: STA AP Not found
|
||||
I (42021) app_prov_handler: Disconnected state
|
||||
```
|
||||
|
||||
### Provisioning does not start
|
||||
|
||||
If the serial monitor log is different, as shown below :
|
||||
|
||||
```
|
||||
I (539) app_prov: Found ssid myssid
|
||||
I (539) app_prov: Found password mypassword
|
||||
I (549) app: Starting WiFi station
|
||||
```
|
||||
|
||||
It means the Wi-Fi credentials were already set by some other application flashed previously to your device. To erase these credentials either do full erase and then flash the example
|
||||
|
||||
```
|
||||
make erase_flash
|
||||
make -j4 flash monitor
|
||||
```
|
||||
|
||||
Or, enable `Reset Provisioning` option under `Example Configuration` under menuconfig. But this will erase the saved Wi-Fi credentials every time the device boots, so this is not the preferred solution.
