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

@Hung Bui. I am measuring consumption using a multi point Power supply. Now i come up with correct measurements as previous power supply had issues with resolution. Following are the observations based on power supply monitor. System starts and goes to Sleep(using sd_evt_wait API) mode immediately after all initialization. Timer starts (for 15 seconds) to wake up device in every 15 seconds. For first 15 seconds(when device is in sleep), the current consumption is 5uA. After 15 sec, timer handler starts advertisement (with TIMEOUT 5 seconds) and consumes ~250 uA (for 5 seconds) and then for next 10 seconds consumes 30uA. Afterwards, It keep on toggling between 250uA and 30uA . Not sure Why it doesn't show 5uA again ? After connection, device consumes 2-3mA. Does this sound alright now ?
