|
|
This plugin allows you to fully control to ESP8266/ESP32 devices connected over WiFi.
|
|
It uses the WebREPL interface embedded in MicroPython to communicate with the device.
|
|
|
|
Getting started
|
|
---------------
|
|
|
|
All you need to do is to flash the MicroPython firmware to your device, enable the WebREPL interface,
|
|
and you can use this plugin to fully control the device remotely without deploying any code to the controller.
|
|
|
|
- Download the `MicroPython firmware <https://micropython.org/download>`_ for your device.
|
|
- Connect your ESP8266/ESP32 via serial/USB port and
|
|
`flash the firmware <https://docs.micropython.org/en/latest/esp8266/tutorial/intro.html#intro>`_.
|
|
For example. using ``esptool`` and assuming that you have an ESP8266 device connected on ``/dev/ttyUSB0``:
|
|
|
|
.. code-block:: shell
|
|
|
|
# Erase the flash memory
|
|
esptool.py --port /dev/ttyUSB0 erase_flash
|
|
# Flash the firmware
|
|
esptool.py --port /dev/ttyUSB0 --baud 115200 write_flash --flash_size=detect 0 esp8266-[version].bin
|
|
|
|
- Access the MicroPython interpreter over serial/USB port. For example, on Linux:
|
|
|
|
.. code-block:: shell
|
|
|
|
picocom /dev/ttyUSB0 -b11520
|
|
|
|
- Configure the WiFi interface:
|
|
|
|
.. code-block:: python
|
|
|
|
>>> import network
|
|
>>> wlan = network.WLAN(network.STA_IF)
|
|
>>> wlan.active(True)
|
|
>>> wlan.connect('YourSSID', 'YourPassword')
|
|
>>> # Print the device IP address
|
|
>>> wlan.ifconfig()[0]
|
|
>>> '192.168.1.23'
|
|
|
|
- Enable the`WebREPL <https://docs.micropython.org/en/latest/esp8266/quickref.html#webrepl-web-browser-interactive-prompt>`_
|
|
interface on the device:
|
|
|
|
.. code-block:: python
|
|
|
|
>>> import webrepl_setup
|
|
|
|
- Follow the instructions, set a password and reset your device. A websocket service should be available
|
|
by default on the port 8266 of your ESP8266/ESP32 and it can accept commands sent by platypush.
|
|
|
|
Requires:
|
|
|
|
* **websocket-client** (``pip install websocket-client``)
