Hello Felix,
I know this belongs to a different thread, but this is a feedback to the low power suggestions you gave.
I am having issues with the DeepSleep_usingLowPowerlibrary, this gives me a whooping 5mA current consumption, while the DeepSleep library gives as low as 6.9uA. I have nothing attached, just my Laptop+USB+FTDI Adapter+Moteino RFM69W
Is there something I'm doing wrong?
I have attached the two codes, though they are the sample codes from the RFM69 library.
