DASH Button RAK611 RAK473 - GPIO PIN(44) Unavailable
I finally got my DASH Button (RAK611 with RAK473) up and running. It works with OTA & just the battery connected. Only last problem to solve is that not all GPIO get initialized. Connecting the serial port the output shows:
GPIO PIN(43) Unavailable GPIO PIN(44) Unavailable
Why is this? how to solve it?!
interestingly, I when connect USB power, it get less errors, but PIN 44 is still unavailable.
SOLVED looks like a power problem. After I charged the Battery the problem is gone!? weird..
