Bluetooth Client
Sample BLE peripheral implementation written in two parts: controller in smartBASIC and host written in Python 3. This software is meant to run on a LairdCP BL652.
The BASIC controller implements a GATT server with custom UUIDs that exposes LHR-specifc characteristics as endpoints to communicate with a mobile app. Its largely a dumb tunnel with one inbound and one outbound interface both on the bluetooth side and the host side.
The Python3 host interacts with the controller through the aforementioned 2 endpoints over a serial connection.
Setup
Setting up the Pi with LairdCP is not covered here, mostly because @damouse is not the one who set it up.
Install required python packages:
pip3 install pyserial
To run the controller, open UwTerminalX, establish a connection with the breakout board, then rightclick the screen and select Compile and Load, choosing gatt_program.sb
To start the host, make sure the program is started, UwTerminalX is off, and then run main.py.
