LTM2MAVLink

A non-coder's approach at a LTM to MAVLink converter. Aimed at passing LTM downlink telemetry to MAVLink-compatible GCSes like MissionPlanner, QGroundCrontrol etc.

Tested on Arduino Pro Mini and ESP8266

Arduino Pro Mini:

LTM telemetry input via AltSoftSerial on Pin D8, default 1200 baud

MAVLink output via hardware serial, default 57600 baud

ESP8266:

LTM telemetry input via HardwareSerial, default 1200 baud

MAVLink via UDP broadcast, SSID = LTM2MAVLinkUDP, password = password

adjust as required in config section
