Hi,

The first peak is of the MCU wake up. The 3 high peaks represent the advertisement on the 3 different channels.

[ToTo]

How much current is the MCU wake up peak(first peak) ?

[junaedi]

The current peak for wake up is around 5,5 mA.

You are right.I tried to enable/disable the channel and resulting different number of peaks according to channel that we used.

Thanks for your help.
