You need to initialize the UART library as well, similar to the UART peripheral example. The retarget functionality use app_uart_put/get functions for stdio retargeting.

Does this work for transferring data through the com ports. I tried it and it stopped outputting on the debug console but, it did not show up on the COM7 I was monitoring on my pc.

Thanks

Hi,

In order to use printf to transmit data over UART, you need to include the Retarget layer for stdio functions.

Add the source file components\libraries\uart\retarget.c to your project, and enable retargeting in your sdk_config.h file:

// <q> RETARGET_ENABLED  - retarget - Retargeting stdio functions

#ifndef RETARGET_ENABLED
#define RETARGET_ENABLED 1
#endif

Best regards,
Jørgen
