I download new RAK811 firmware from github and tested it on my WiseNode.
I can say it’s working really good!
I tested new firmware in two ways on my boards:
- Updating firmware with USB-UART in BOOT0 -> High mode.
- Updating firmware with ST-Link V2 programmer in BOOT0 -> Low.
In first way of programming, everything works fine.
But there is a strange problem when programing in the second way!
Its about “at+join=otaa” command because it returns Error -1 when sending this command.
It’s really strange because all other Commands work fine! All of them!
I used two of this modules for P2P transfer and it worked fine again but about join command it just returns Error -1.
Problem becomes complicated when you want to program modules in the second way again, Because it will not respond to join command after one time being programed the first way!
I know it sounds crazy, But you can test it and see what is the problem!
