[nRF9160] Transmit AT command with UART

[DDYD1]

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.

Hi,

I'm currently trying to send AT Command using an external MCU or USB to UART to check LTE on the NRF9160.

Which external MCU do you use? How do you send AT commands? Where do you send AT commands from?

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.

Can you provide more information about your problem? What is "not responding"? Do you have any log and command output?
What is the reason for changing pins? How did you do that?

Best regards,
Dejan

Fortunately, I solved the problem by connecting an external input to the RX of uart0!
