Change beacon Minor Value

[ninoq]

This suggests it should be possible to change the beacon advertising content in response to events such as a GPIO input. I'm using nrf52 DK running the beacon example (SDK 12.2.0) which I've modified slightly so that GPIO inputs trigger a 20 second advertising burst. I want to be able to change the Minor Value so that a mobile app can distinguish which GPIO input triggered the advertisement.

I'd appreciate some guidance on how to approach this and if possible links to example code etc.

Yes.

I meant using sd_ble_gap_adv_data_set(), as this is the fastest way to update and hence the CPU runs for less time and takes less overall power

I use this as I update the data every time my smart beacon advertises

I'm using the beacon kit nRF51822 and want to do the same ninoq asked. But i don't understand his solution (maybe it's because i'm new in programing Nordic products). I know that the array entries [20] and [21] are for the MINOR values and I know what advertising_init() and -start() are for, but:

1. I have no m_beacon_info in the example (ble_app_beacon), so where do I have to change the value?
2. can I call the -init() and -start() in the main-loop?

@Andreas: Please have a look in advertising_init(). How do you advertise beacon data ? Which SDK you are using?
