I installed the Edison module into pixhawk2, and flash apsyns-edison image to Edison, now I can run linux in Edison successfully, but if I run command below:
spsync@apsync:~/dronekit-python/examples/vehicle_state$ python vehicle_state.py --connect '/dev/ttyMFD1,57600'
it print below:
Connecting to vehicle on: /dev/ttyMFD1,57600
link timeout, no heartbeat in last 5 seconds
I am confused about it, woule you please give me some hints, thanks in advance....
