looking for advise, pulled my Mindstorms 8547 kit out of storage and started to play with it after several years of inactivity. Found that the Color Sensor, Ultra Sonic Sensor, and the postion read back on motors all do not function. I downloaded the latest software and version 1.31 firmware.
Any idea what is going on, do I need to go back to a previous version firmaware to get things to work as they did originally?
Any advice is aprreciated, thank you.
