ESP Provisioning Tool
NAME
esp_prov
- A python based utility for testing the provisioning examples over a host
SYNOPSIS
python esp_prov.py --transport < mode of provisioning : softap \ ble \ console > [ Optional parameters... ]
DESCRIPTION
Usage of esp-prov
assumes that the provisioning app has specific protocomm endpoints active. These endpoints are active in the provisioning examples and accept specific protobuf data structures:
Endpoint Name | URI (HTTP server on ip:port) | Description |
---|---|---|
prov-session | http://ip:port/prov-session | Security endpoint used for session establishment |
prov-config | http://ip:port/prov-config | Endpoint used for configuring Wi-Fi credentials on device |
proto-ver | http://ip:port/proto-ver | Version endpoint for checking protocol compatibility |
prov-scan | http://ip:port/prov-scan | Endpoint used for scanning Wi-Fi APs |
custom-data | http://ip:port/custom-data | Optional endpoint for sending custom data (refer wifi_prov_mgr example) |
PARAMETERS
-
--help
Print the list of options along with brief descriptions -
--verbose
,-v
Sets the verbosity level of output log -
--transport <mode>
Three options are available:softap
For SoftAP + HTTPD based provisioning. This assumes that the device is running in Wi-Fi SoftAP mode and hosts an HTTP server supporting specific endpoint URIs. Also client needs to connect to the device softAP network before runningesp_prov
ble
For BLE based provisioning (Linux support only. In Windows/macOS it redirects to console). This assumes that the provisioning endpoints are active on the device with specific BLE service UUIDsconsole
For debugging via console based provisioning. The client->device commands are printed to STDOUT and device->client messages are accepted via STDIN. This is to be used when device is accepting provisioning commands on UART console.
-
--ssid <AP SSID>
(Optional) For specifying the SSID of the Wi-Fi AP to which the device is to connect after provisioning. If not provided, scanning is initiated and scan results, as seen by the device, are displayed, of which an SSID can be picked and the corresponding password specified. -
--passphrase <AP Password>
(Optional) For specifying the password of the Wi-Fi AP to which the device is to connect after provisioning. Only used when corresponding SSID is provided using--ssid
-
--sec_ver <Security version number>
For specifying version of protocomm endpoint security to use. For now two versions are supported:0
forprotocomm_security0
1
forprotocomm_security1
-
--pop <Proof of possession string>
(Optional) For specifying optional Proof of Possession string to use for protocomm endpoint security version 1. This option is ignored when security version 0 is in use -
--service_name <name>
(Optional) When transport mode is ble, this specifies the BLE device name to which connection is to be established for provisioned. When transport mode is softap, this specifies the HTTP server hostname / IP which is running the provisioning service, on the SoftAP network of the device which is to be provisioned. This defaults to192.168.4.1:80
if not specified -
--custom_data <some string>
(Optional) An information string can be sent to thecustom-data
endpoint during provisioning using this argument. (Assumes the provisioning app has an endpoint calledcustom-data
- see provisioning/wifi_prov_mgr example for implementation details).
AVAILABILITY
esp_prov
is intended as a cross-platform tool, but currently BLE communication functionality is only available on Linux (via BlueZ and DBus)
For android, a provisioning tool along with source code is available here
On macOS and Windows, running with --transport ble
option falls back to console mode, ie. write data and target UUID are printed to STDOUT and read data is input through STDIN. Users are free to use their app of choice to connect to the BLE device, send the write data to the target characteristic and read from it.
Dependencies
This requires the following python libraries to run (included in requirements.txt):
future
protobuf
cryptography
Run pip install -r $IDF_PATH/tools/esp_prov/requirements.txt
Note :
- The packages listed in requirements.txt are limited only to the ones needed AFTER fully satisfying the requirements of ESP-IDF
- BLE communication is only supported on Linux (via Bluez and DBus), therefore, the dependencies for this have been made optional
Optional Dependencies (Linux Only)
These dependencies are for enabling communication with BLE devices using Bluez and DBus on Linux:
dbus-python
Run pip install -r $IDF_PATH/tools/esp_prov/requirements_linux_extra.txt
EXAMPLE USAGE
Please refer to the README.md file with the wifi_prov_mgr
example present under $IDF_PATH/examples/provisioning/
.
This example uses specific options of the esp_prov
tool and gives an overview of simple as well as advanced usage scenarios.
