This might be a dumb question. I have started to play with this robot with raspberry pi two days ago. I did some simple stuff, like- move around and sensor reading etc. But since yesterday night, It seems like I cannot send any command. The built in clean, dock functions are working perfectly but I cannot do anything using the same python code that I already used before. Its behaving like nothing is going through the Rx.

Can you suggest what might go wrong? Thanks

It's possible that you may have switched the baud rate at some point. Try resetting the robot (press dock and spot at the same time for ~10 seconds, or take the battery out and put it back in).

This will cause the baud rate to go back to the default 115,200
