Need to get nRF 9151 UART <=> IOT to work

[RamizB]

hello,

I have nRF9151 and would like to connect UART1  (Rx PO.28 & Tx PO.29) to an external IOT device.  it only supports the Tx/Rx port. There is HW control.

My goal is to send one character 'A' on the port and then receive 2 characters. i can't make it to work. I followed the instructions to configure the device but not able to make it work!

Attached provide the configuration of application with simply loop at the to do the actual Tx/Tx and would greatly appreciate any help to make this work for me.

Thanks for your help in advance.

regards
