[ClientStub] send request error.

[Lin-jun-xiang]

Problem

• Using the unitree app API mode to connect the go2 to the same Wi-Fi as the computer. The network card name is set as Wi-Fi which get by ipconfig>> InterfaceAlias: Wi-Fi.

• When running example/helloworld/, the publisher and subscriber work smoothly and produce the expected results.

• However, when executing test.StandDown(), an error occurs with the message "[ClientStub] send request error. id=xxx".

The client error cause from: https://github.com/unitreerobotics/unitree_sdk2_python/blob/bd24b5be05b67eb044ebcec9f35d0698040b5360/unitree_sdk2py/rpc/client_stub.py#L50-L55

I have used debug mode, then find the self.___publication_matched_count is 0 which cause the client error.

However, I have no idea why the self.___publication_matched_count is 0.

Environment

• Go2: go2 air and go2 pro have been tested
• Operating System: Both Windows 10 and WSL2 (Ubuntu20.04) have been tested
• Python Version: 3.8.6

Hi @Lin-jun-xiang , I'm trying to run the high-level control example go2_sport_client.py using the unitree_mujoco simulation and specifying the network interface lo. I encountered the same error message you've mentioned: [ClientStub] send request error. id: 252906806156372 Did you figure out how to solve it?
