Hi hedoluna, when you simply initiate uart with uart_init function (as the peripheral example), you can call uart_put or uart_get to communicate. What wasn't working for me was pins. So for sparkfun breakout board I changed the rx pin to 26, tx pin to 27. Sorry for the late answer!

Hi, asabuncuoglu13, would you please add HOW you modified the UART part? :) Thanks in advance :)

Okay, I configured pins manually after this answer, but the problem for me was uart, example did not work for sparkfun breakout board so I modified the uart part of ble_app_uart example in the peripheral. I wanted to share my experience.

Thanks for your help.

Hello asabuncuoglu13

You can find examples of how to use the I2C by looking at the TWI examples that comes with the SDK. You can find these in the [SDK Folder]\examples\peripheral folder. Description of the SDK13 examples can be found at the infocenter here.

The choice of pins is made when the TWI is initialized, where a config variable of type nrf_drv_twi_config_t is created. Here you have the .scl and .sda variables which will contain your pin numbers.

Best regards
