Thank you. Your advice gave me a clue on where to start and I found the place to edit. Michal's response confirmed what I had done. Worked like a charm.

Thank you, I was able to modify that file earlier this morning and it worked like a charm. The watch picked it right up. Now to figure out how to access the GPIO pin and modify the example to calculate real world variables.

Hi,

regarding the first question, the ANT+ Network key is defined in components\ant\ant_key_manager\config\ant_key_manager_config.h in #define ANT_PLUS_NETWORK_KEY - that's where you should modify it. Then after re-compiling and re-programming the DK your watch should be able to find your transmitter example.

When it comes to controlling an external device, take a look at HW peripheral examples - they show the usage of HW peripheral drivers, some of which use external modules.

Regards, Michał

You could try ant_plus_key_set() in softdevice_setup().
