RE: How to vary the LEDs blink rate

Thanks for reply. I thought that the BATTERY_LEVEL_MEAS_INTERVAL applies only once during initialisation. (Currently 2000ms) Right? Or do you suggest that I can call the app_timer_start(m_battery_timer_id, BATTERY_LEVEL_MEAS_INTERVAL, NULL); function again in order to modify the timers rate? That would be a solution.

Yeap the update shows what I was looking for. Many thanks.

If you look at for example ble_app_bps in nRF51 SDK 7.1.0, there are two function calls in the main function for the application timers, timers_init() and application_timers_start(). If you look at application_timers_start(), the battery service timer is started with:

app_timer_start(m_battery_timer_id, BATTERY_LEVEL_MEAS_INTERVAL, NULL);

Changing the value of the BATTERY_LEVEL_MEAS_INTERVAL constant will change interrupt frequency of this application timer.

Update 14.1.2014 If you want to update the application timer update freqeuency dynamically, I think the best way to do that is to stop the timer and start it again with a new value. Some discussion about that is on this thread
