Hi there,

I’m recently trying to do some tests with go1 using the unitree sdk, but when i try to run the “example\_walk” code it returns the next error:

> [Error] Bind client ip&port failed: Address already in use

Then i used lsof command inside pi@raspberrypi to see which processes were running in ports 8080 and 8082 this was the result:

I don’t know what are this processes related to nor if they are really the problem here so if you could give me some suggestion i’d appreciate it.  
I also tried to run the code with multiple ip/port combinations but it always returned the same error.
