Redbear Duo, fw version 0.3.1, cloud connected. In listening mode I can access the device via putty to COM23.
Tools > Get Board Info returns:
BN: Unknown board
SN: Upload any sketch to obtain it
But Tools > Board has no option for the Redbear Duo, and Board Manager doesn’t return any likely results either.
The default option is “Arduino/Genuino Uno” - I’m assuming that won’t work?
