UART to Peripheral

[SKo]

Hello, we want to establish a UART communication between the Dynastream N548M8CB Module and a TI Mikrocontroller. I have tested the UART loopback example with the pca10028 board. It worked fine. How can I adapt the code for pca10028 to the N548M8CB module? Is it possible to use the "DM_LOG(" funktion?

Hi Sko,

In the example you mentioned can you comment out this below line

#define ENABLE_LOOPBACK_TEST

and see if that test compiles and works fine for you. You do not need to connect UART TX and RX if you are not running this example as a loopback. Instead you need to open a serial emulator on your PC to test it. If it still works then APP_LOG should be enough for you

#define APPL_LOG                        app_trace_log

Thanks for your quick response. I am able to test the case you described. I can send commands with this example to my pc and log them on hterm. I want to test this example on my N548M8CB modul. This modul uses the same Nordic chipset N51422 but there are no uart commands on the tx output from the modul. Do you have some ideas?

I solved this problem, it was very confusing because of the mapped GPIOs.

did you have same pins connected to Segger chip if not how did you solve this?

Sorry, I don´t understand what you want to know. I the uart example TX Output pin is mapped to P0.9 at the nrf51422 chip. I was measuring at the wrong Pin at the Dynastream Board. Shame on me!
