Power Consmuption issue in nrf51 during advertising packets

[Brajesh]

Hi All,

My goal is to advertise the generic packets untill a GPIO interrupt occurs. So in order to achieve low power consumption I have increased the time interval of those packets being advertised from 40ms to 3 seconds. While scanning i am able to see the packets in every 3 sec, but as intended i don't see any reduction in power consumption. With both the intervals, it consumes same 10mA. Am i missing something on this, please suggest.

Any suggestion would be well appreciated.

Thanks

Okay @Hung Bui, will get back to you with stats in SDK examples, but can you please guide me how can i read CPU processing time ?

@Brajesh: No, you either need to calculate it, or you can try to toggle a GPIO pin before and after you finish the task. Then use a logic analyzer or oscilloscope to measure the distance between.
