I installed the Edison module into pixhawk2, and flash apsyns-edison image to Edison, now I can run linux in Edison successfully, and I have set the parameters:
SERIAL2_PROTOCOL = 1
SERIAL2_BAUD = 921
LOG_BACKEND_TYPE = 3
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 not sure that baut rate, so I change the baut rate, and try another command below:
spsync@apsync:~/dronekit-python/examples/vehicle_state$ python vehicle_state.py --connect '/dev/ttyMFD1,921600'
unfortunity, the same error," timeout"
I am confused about it, woule you please give me some hints, thanks in advance....
