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
