I'm trying to connect a GoPlus2 to my M5stack grey using Flow 1.9.5 firmware.

Code is clear and I only have a single Flow block for testing: "Set Servo S1 angle 0".

As soon as I download or run it I get a red error screen stating "GoPlus2 module maybe not connected".

M5stack is running from GoPlus2 battery and no bottom.

Am I missing something?
Thanks!
