Hi,
I have a working module (at least the application with LoraWan & BLE communication), but I cannot update the module anymore. Nrfutil is not working because it seems to be some problem with entering into the boot mode.
I tried two scenarios to analyze what’s happening:
- Set the device into AT mode before sending AT+BOOT. AT mode is set correctly, the devices resets after boot command but the COM port dissapears and never comes back until power toggle is applied. Then, the application starts normally.
- Send AT+BOOT without being in the AT mode (I read somewhere, it should work). The device reboots but the application starts normally (no boot mode).
Any suggestions?
