@Aryan may I start a new thread asking about the led problem ? ? ?

@Aryan yes, & it was 5mA only when the command controls leds is handled, any other services events don't increase the current to such level, I remeasured the current consumption on the connected mode, it was 35 uA & while bonding it was 380 uA, which is good for my application, but 5mA is very high ....

If you are using nRF development board (for eg PCA10028) then the current measurement will not include LED power. Please read the data sheet for it. If you are using custom board then most probably the reason for increase in current is due to the LED's. Have you tried to measure the current by turning LEDs off?

the problem is that the current is very high in the normal mode while it in the state waiting for event to handle....

@Aryan I hope I answered you in the last comment ;)

@Marius I measured it through all the advertising interval & while it connected, I measured the current at each event the currrent increases to 5 mA, I think it's due to powering the LEDS to turn on....

@awneil I measured the current by unshort sb9 and connected the avometer to the two pins as said in the dk userguide

+1 to Marius, The advertising interval and connection interval matters for the current consumption because the system will be powered on for every radio activity for pre and post processing inside the softdevice.

Which connection interval did you measure and to which advertising interval did you compare it? That makes a big difference.

How, exactly, did you measure that?
