CC2642R-Q1: Current and Advertisement Sets variation in BLE stack or application

1. We are using the Simple Peripheral example code with all default parameters- the device is continuously advertising
2. We are measuring the current consumption of board by using voltage drop across a 100R series resistor
3. We are seeing variations in
   1. Two consecutive current peaks – may be referring to two advertisement sets
   2. Peak current consumption in each advertisement interval

Here are the waveforms-

1. Variation in current consumption-

1. Variation in current consumption and advertisement sets

What could be the reason for variation in current consumption as well as timing?
