It's a standard C function, did you #include <string.h>?

I am not able to compile using that function. I get a "variable or field 'nus_data_handler' declared void" error. I must be missing a library or something.

BLE UART is effectively the interrupt. It reacts when it gets an inbound message. Do a strncmp and then act accordingly.

So one doesn't need an interrupt then? The static void nus_data_handler(ble_nus_t * p_nus, uint8_t * p_data, uint16_t length) is constantly running in the background? I can then run a string comparison of "p_data" to "data" (the information sent from the nRF UART app) and if they equal 4 (the value sent by the button), then I can just go to a different loop or portion of the program? Interesting. I will let you know how that works.

Received data through BLE UART ends up here

static void nus_data_handler(ble_nus_t * p_nus, uint8_t * p_data, uint16_t length)

So in that function add a little test that compares p_data to some key and then call your stop function/set your stop flag when p_data represents the right instruction.
