Error when trying to connect via serial

[mtonnberg]

When I try to connect with to my drone with

drone = System()
await drone.connect(system_address="serial:///dev/serial0:57600")

It just get stuck forever. If I try to run the server directly with

sudo ~/.local/lib/python3.9/site-packages/mavsdk/bin/mavsdk_server serial:///dev/serial0:57600

I get the following error:

[10:16:19|Info ] MAVSDK version: v2.2.0 (mavsdk_impl.cpp:26)
[10:16:19|Info ] Waiting to discover system on serial:///dev/serial0:57600... (connection_initiator.h:20)

I have tried to build from source with the same result. The system is Raspberry pi Zero 2 W on 64bits Bookworm.
I can connect to the FC via MavProxy so I can interact with the drone via QGroundcontrol that way but not via MavSDK.

I have seen this one recently. Let me try to remember what the problem was. A yes. Something about gRPC ssl dependencies.

Should be fixed with: mavlink/MAVSDK#2223

Just wait for the next release. I'm on it...

Try https://github.com/mavlink/MAVSDK-Python/releases/tag/2.1.0
