This video just show how
MicroPython bluetooth module examples
run on ESP32-C3, Ai-Thinker NodeMCU ESP-C3-32S-Kit and Espressif
ESP32-C3-DevKitM-1, both running MicroPython
v1.19.1 on 2022-06-18. Finally, have bi-direction BLE communication between ESP32-C3 dev. boards.
MicroPython bluetooth module provides an interface to a Bluetooth controller on a board. Currently this supports Bluetooth Low Energy (BLE) in Central, Peripheral, Broadcaster, and Observer roles, as well as GATT Server and Client and L2CAP connection-oriented-channels. A device may operate in multiple roles concurrently. Pairing (and bonding) is supported on some ports.
Note: This module is still under development and its classes, functions, methods and constants are subject to change.
