AT commands after rerouting UART0

[Jace]

I would like to use AT commands to get the IMEI on a custom board that has an nRF9160.

In preparation for this I am attempting to get AT communication working on a NRF9160dk after rerouting UART0.  

I have the AT sample application running and working before rerouting UART0.  I can see output and send AT commands.

Now I've rerouted UART1 with these settings:

&uart0 {
status = "ok";
current-speed = <115200>;
tx-pin = <20>;
rx-pin = <21>;
rts-pin = <6>;
cts-pin = <7>;
};

Then I connected an FTDI to pins 20 and 21.  I can see the output of the device from the FTDI serial connection.  I am not able to send AT commands over that line.

Any help would be appreciated!

Hi!

The pins you've chosen for RTS and CTS are already used for Button 1 and Button 2 on the DK, see here.

Try using P0.10 and P0.11 instead and see if that fixes it.

Best regards,

Heidi
