I‘m trying to use a ESP8266 Module to communicate with ArduPilot and Mission Planner. I‘ve got it all set up and it seems like Mission Planner connects to ESP, but it says that there’s a timeout error and no heartbeat could be detected. Got any ideas on how to solve this issue?
MAVLink detects that have another device to connect to it via heartbeat messages, it works like a “vital sign” of the other device, streamed at 1Hz. Be sure that your ESP device is receiving ardupilot FC messages and passing thru to Mission Planner.
