# BLE based Provisioning Example (Legacy)
|
||||
|
||||
> Note: It is recommended to use the new `wifi_prov_mgr` example which is based on the simpler `wifi_provisioning` APIs. Check this example only if you wish to use lower level provisioning and protocomm APIs and want more control over the handlers.
|
||||
|
||||
(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 `$IDF_PATH/tools/esp_prov`). Make sure to satisfy all the dependencies prior to running the script.
|
||||
|
||||
Presently, `esp_prov` supports BLE transport only for Linux platform. For Windows/macOS it falls back to console mode and requires another application (for BLE) through which the communication can take place.
|
||||
|
||||
There are various applications, specific to Windows and macOS platform which can be used. The `esp_prov` console will guide you through the provisioning process of locating the correct BLE GATT services and characteristics, the values to write, and input read values.
|
||||
|
||||
### Configure the project
|
||||
|
||||
```
|
||||
idf.py menuconfig
|
||||
```
|
||||
|
||||
* Under Example Configuration set the following :
|
||||
* Security Version (default 1)
|
||||
* Proof of Possession (default "abcd1234")
|
||||
|
||||
### Build and Flash
|
||||
|
||||
Build the project and flash it to the board, then run monitor tool to view serial output:
|
||||
|
||||
```
|
||||
idf.py -p PORT flash monitor
|
||||
```
|
||||
|
||||
(To exit the serial monitor, type ``Ctrl-]``.)
|
||||
|
||||
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
|
||||
|
||||
## Example Output
|
||||
|
||||
```
|
||||
I (550) app: Starting BLE provisioning
|
||||
I (1130) app_prov: Provisioning started with BLE devname : PROV_261FCC
|
||||
```
|
||||
|
||||
Make sure to note down the BLE device name (starting with PROV_) displayed in the serial monitor log (eg. PROV_261FCC). This will depend on the MAC ID and will be unique for every device.
|
||||
|
||||
In a separate terminal run the `esp_prov.py` script under `$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 --transport ble --service_name PROV_261FCC --sec_ver 1 --pop abcd1234 --ssid myssid --passphrase mypassword
|
||||
```
|
||||
|
||||
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
|
||||
idf.py -p PORT 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 :
|
||||
|
||||
```
|
||||
BLE client is running in console mode
|
||||
This could be due to your platform not being supported or dependencies not being met
|
||||
Please ensure all pre-requisites are met to run the full fledged client
