Wow, nice captures. I think with the seesaw you're probably seeing the switchmode power supply kicking in?
What do you mean by 12uA? 12uA average over that time period?

Sorry for not explaining my measurements in more detail in the first place.
I've used a CR2032 coin cell as energy source and measured the voltage drop on a 10R high precision resistor (uCurrent). Therefore the seesaw supposedly shows the different phases of the uC cycle:
 power up
 preprocessing
 transmit (I assume 3 consecutive retransmits)
 power down
I'm using the DSO's math functions to calculate the integral (shown in purple) on channel 1 (yellow). The integral of this particular measurement is 11.44uU = 11.44uA/advertisement. However measurements are never exact. Hence I decided to state the value at ~12uA/advertisement, in my post above.
 power up
Below my second try, peaks are significantly higher as I anticipated.
(I've inserted a reference to the previews scale)
Each advertisement is ~12uA.
