How to vary the LEDs blink rate

Question

Hi all, 
 I am trying to figure out how to change the LEDs blink rate on the go. 
 I have set up the timers_init() and let say every 500ms sensor data is read on dev kit and transmitted to a smart phone. According to the sensor data I want to change the blink rate of the LED/LEDs on dev kit. What would be the best method to achieve this? 
 Thanks for advice ;)

Hi 
 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
