Getting time ticks or adv packet count

[kerem]

Is there an internal counter for the number of packets transmitted since power on?

Im trying to change the advertising packet content after a timer is expired or a certain count, but i get invalid parameter error in advertising_init() and advertising_start() functions when i call them for the 3rd time. I think this can solve the problem about changing the packet but im trying to understand when to change it first.

What would be the preferred approach for getting the timer ticks since the board is powered on or get number of packets transmitted so far?

Im using ble_app_hrs example with nrf51-dk on sdk6.1.0 and sd 7.0.0.

I think you should be able to use the Radio Notification for this. Please see this tutorial.

Im setting the advertising interval inside advertising_init() via adv params, same as the ble_app_hrs example. I will change it manually and try again.
