Issue: I am running a RAK7258 with success since October 2019 now, with Things Network. When I tried to upgrade its firmware to version 64 or 65 (r208 or r209) the device seemed to be working but stopped forwarding the data packets to the TTN routers. Firmware 63 works fine. I flashed the device several time so the problem is reporductible. Any help is appreciated

Details: Firmware Version 1.1.0063_Release r205 (last one working!)
