  • All you need to do is start sending Channels packets out a UART at 115200 baud and the TX will fire up and start sending them at whatever packet rate it is already configured for. You'll need to disable UART inversion on the TX though because external modules are half-duplex inverted (stupid legacy stuff!) The protocol I've documented here: https://github.com/ExpressLRS/ExpressLRS/wiki/CRSF-Protocol
