Hello,
I have both a GoPiGo and a GrovePi which I use together semi-frequently. I recently ordered some new sensors to use with them and found that the GoPiGo could no longer communicate with the GrovePi (with or without the new sensors attached). I disconnected the pair and connected just the GrovePi to my RPi and everyhting was fine. I’m not sure why out of the blue the GrovePi doesn’t work with the GoPiGo anymore, its been connected the same way (through I2C) for months now, with no issue.
I ran the troubleshooting test on the GrovePi whilst it was connected to the GoPiGo and have copied the log file below:
