I use a OLIMEX nRF8001 module with ATMEGA328 at 3v3. Using the "helloWorld" serial example sketch, I measure a current of approx 400-600uA. However, if I use the calculator in the nRFgo Studio, I get approx 16uA.
Two questions:
- Can someone explain the big difference?
- How can I reduce this current consumption (detailed please as I'm quite new to the platform)?
PS When I look at the current with my scope (over 100R resistor), I see approx 6mA current bursts every x ms.
