@nadvorvo try to lower the speec.
I hope you can help in this matter.
Thanks a lot for writing back.
I am following this tutorial:
expansion board: V3.1
I am downgrading to version GPy-1.20.2.r1.tar.gz
I do not connect a jumper cable or wire between G23 and GND (only for version 2.0)
LED blinks blue (GPy not in programing mode).
It fails with message:
pycom failed to connect to esp32 invalid head of packet (\x08)
