Error running python examples about mavsdk-python HOT 6 CLOSED

SWEEEEEET!!!

This is awesome! Really. Before the renaming the process was a little bit involved but not too hard, but now is super easy.
Thanks so much!
I tested the takeoff and land example in different udp port and it also works. Assume serial port should work fine as well?

Hello!

Sorry about that, we recently renamed the project to MAVSDK, and therefore there are some incompatibilities between the main branches of both project.

To use MAVSDK-Python, just run pip install mavsdk (make sure you have python3.6+, it may mean pip3 install mavsdk).

Let us know how it goes!

Hi Jonas,
Is the backend going to be installed pip? So far, I can install the sdk without errors. The issue is I keep getting these UNIMPLEMENTED return codes from the gRPC server:

grpc._channel._Rendezvous: <_Rendezvous of RPC that terminated with:
status = StatusCode.UNIMPLEMENTED
details = ""
debug_error_string = "{"created":"@1561335925.969796887","description":"Error received from peer ipv4:127.0.0.1:50051","file":"src/core/lib/surface/call.cc","file_line":1041,"grpc_message":"","grpc_status":12}"

I followed the guide in README to install the backend. I'm connecting it to px4 sitl and this is stdout:

I think the server is connecting with the sim but there seems to be a disconnect between the python messages and the server's?

If you have any idea how to go about this, troubleshoot, it will be greatly appreciated.

Yes, it will, and those two versions will match :-).

Exactly, because of the renaming last week. I'll try to fix that during this week, but in the meantime you should try with pip3 install mavdsk ;-).

One thing to note, though (and I will update the examples as well): with the pip-installed MAVSDK, you need to start the backend manually, with start_mavlink(). So for instance, add the following just after this line:

from mavsdk import start_mavlink

start_mavlink()

After running that command, you can see on the list of processes (e.g. running top or htop) that mavsdk_server is running. And it stops when the python example stops.

Does that help?

from mavsdk-python.

Great! Serial port should work as well, indeed!

Sweet!
Thanks so much. I'm closing this
