RAK5205 not response

I’m sending AT+send command continuously to the device and sometimes it enter state of no response. See below screenshot of the Serial Tool
Couldn’t find any way to continue except to disconnect the USB to the host.


HI @sagis what is the time between every at+send?

  1. at+send=lora:…
  2. Wait 3-5 sec for response
  3. at+set_config=lora:dr:3 # I need it for long packages - 118bytes
  4. Wait 1sec for response
  5. at+send=lora:…

and this can work for hours until stuck with no response.


This is strange. Do you have the serial log? Any RUI API Errors?
