Thanks for the quick reply.
I had to leave on an unexpected business trip and don’t have access to the sources right now.
I used settings fron Arduino code samples. The effect can be measured only when disconnected from USB because the device won’t draw power from the battery when connected. I didn’t measure consumption via USB yet.
I was just wondering, why an unused or idle WiFi draws more power than a connected WiFi.
