RAK5205 not response

Hi,
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.

Thanks!

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

sagis · February 24, 2020, 11:24am

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

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

Thanks

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