Hi,
I've just finished building a track and field timing module that I've replicated from here. The project consists of two modules, a Start and Finish module. The finish module has two LEDS, one for power (which turns on when the module is powered on) and another one (not yet functional) to indicate that both modules have established a connection. However, it seems that the original creator of the project did not complete the code for this action to take place. Both modules use NRF24L01 which work with no issues.
I would like some help with creating some code for the Finish Module to check for a established connection with the Start Module when turned on and light up the second LED.
I've attached the code for both modules. Thank you
