Issue: Can not test RAK4631 with baseboard 5005
I tried to test the RAK4631 but it can not be tested.
I sent the serial with (at+ver=?) but no response from the board.
I even tried with RAK SERIAL PORT TOOL but no response.
Everything is correct, Port Number etc.
I already tested the things as far as I can find from this forum.
And the attached photos are for reference for the problem that I am facing now.
I tested with some RAK Wisblock RUI example programs in arduino.
I’ve found out that from the error, it said that (“Device is either not in bootloader mode, or using an unsupported bootloader”).
So I re-uploaded the bootloader using from the beegee mentioned (Bootloader Fails to upgrade via BLE - #3 by beegee) but the problem is not solved.
Can someone give me some suggestions about that issue?
It already took me 3 days to solve this one but no progress.
