connect() hangs with no info why on Cube Orange #1048

Open siadajpan opened 4 years ago

siadajpan commented 4 years ago

I'm running dronekit on NVIDIA Jetson Nano connecting through UART with Pixhawk Cube Orange. dronekit version = 2.9.2 pymavlink version = 2.4.9 python version = 3.6.9

After running mavproxy.py --master=/dev/ttyTHS1 --baudrate=115200 I'm getting:

Connect /dev/ttyTHS1 source_system=255
Log Directory:
Telemetry log: mav.tlog
Waiting for heartbeat from /dev/ttyTHS1
MAV> online system 1
STABILIZE> Mode STABILIZE

but after running 

>>> import dronekit
>>> v = dronekit.connect('/dev/ttyTHS1', baud=115200)

It hangs without showing anything more (not even heartbeat timeout), so it seems like heartbeat is present. I can see the some incoming messages every second after running screen /dev/ttyTHS1. I was also trying to set flag wait_ready to False, but without success.

Try a different baud rate? Check what the Pixhawk is expecting in Mission planner and use that rate, but default is 57600 I think.

Yes, I set baudrate in mission planner to 115200 and protocol to Mavlink2. I'm also using the same baudrate in mavproxy.py run

Hi @siadajpan , do you find solution? I have the same issue but on Jetson Xavier. When connecting using mavproxy.py on Xavier, it shows only: mavproxy.py --master=/dev/ttyTHS0 --baudrate 921600 WARNING: You should uninstall ModemManager as it conflicts with APM and Pixhawk Connect /dev/ttyTHS0 source_system=255 Log Directory: Telemetry log: mav.tlog Waiting for heartbeat from /dev/ttyTHS0 MAV> online system 1 ALT_HOLD> Mode ALT_HOLD

While connecting using mavproxy.py on Ground Computer, it shows more information: mavproxy.py --master=/dev/cu.usbserial-AD0K5Q02 Connect /dev/cu.usbserial-AD0K5Q02 source_system=255 Log Directory: Telemetry log: mav.tlog Waiting for heartbeat from /dev/cu.usbserial-AD0K5Q02 MAV> GPS lock at 0 meters AP: GCS Failsafe Cleared online system 1 ALT_HOLD> Mode ALT_HOLD AP: PreArm: Radio failsafe on AP: ArduCopter V4.0.4 (40502bd9) AP: ChibiOS: d4fce84e AP: CubeOrange 0026003A 34385111 31373439 AP: RCOut: PWM:1-12 AP: Frame: QUAD

In addition, when I change mode from Ground Computer, it works but it show nothing after typing the syntax on Xavier. When I change mode from Ground Computer, the new mode still be synced on Xavier console. Anyone has a clue? Thank a lot,
