Hello.
I'm currently trying to send AT Command using an external MCU or USB to UART to check LTE on the NRF9160. The board I use is the nRF9160DK. I changed the pins of UART0 to p0.0 and p0.1 to fix my problem, but it is still not responding. Any help would be appreciated.
In addition, I will upload the file that I have worked on. I worked on the basis of one of the nRF examples, at_client.
