Printf with NRF52

[YCH]

Hello!

i am testing the nrf52 ble uart example. i am able to communicate with the BLE smartphone application (rx and tx) but i cant seem to get printf commands to print in the terminal. this is a bit disturbing since i want to make sure UART comms work fine and as i understood from the instructions the printf is supposed to send data to the UART.

could you please advise and help understand what seems to be the problem?

Hello, YCH!

I have answered a question related to UART logging.

It is mainly about configuring the sdk_config.h file.

Would you try the configuration described in my answer from the link?

If this doesn't work, add comments, please.

-Best Regards

What IDE are you using? I was experiencing a similar problem with Segger Embedded Studio.

The fix for Segger is to implement a custom function to do the printf.. See here

i am using IAR embedded workbench.

After some further testing i have found out that the printf function as implemented in this example with show output in termional only if the string ends with new line character ('\n'). besides that it works fine.

thanks for your responses and help.
