Issue: Adapted datarate may not working so i decide to try another firmware.
Setup: Rak811 with CP2102 usb UART. RAK811 Version:126.96.36.199.H.beta2. RUI 3.05. AS923
Details: When using LoraButton upgrade tool, only Enter BOOT mode success command appear and nothing happen after. When using stm32cubeprogrammer, the chip can be found over uart but cannot do anything include read/wirte. (when trying it said Chip is under protected mode).
Please help me to check adr at this firmware version, i tested Wisnode rak811 at 188.8.131.52 and it work perfectly!
