Hi,

I’m working with a daemon in python who send the ‘play’ command to the dashboard.

Sometimes, the polyscope freeze when I wait the answer.

It’s strange because I have some others commands (like ‘robotmode’) and it works perfectly.

Anyone know where this bug could come from ?

Thanks, Thierry

Update :

After several research, I have found that the timeout exception is raised.  
But I don’t know why…

Anyone has an idea to solve this problem ?

I come back after a while, but I still have this problem.

I have found another thing.

When I sent the ‘play’ command, I always have a timeout exception when I read the answer.

But. when I sent another command after that, I read the play answer : ‘Starting program’

Anyone know why and can help me with this problem ?
