In the main.c file you will find a function called nus_data_handler(ble_nus_evt_t * p_evt), which is called every time the nRF device receives some data from the connected central (phone typically).

The p_evt parameter contains the data, stored as a byte buffer, and you can get access to these bytes through the p_evt->params.rx_data.p_data and p_evt->params.rx_data.length fields.

To store this to a variable you can add your own code here, and remove the original code writing to the UART if you want.

Best regards
