As far as i understood it supports 4.2 BLE because using it i'm able to see packets between nRF52 central and peripheral boards (HRM example). Is it so?
Question:
I am confused about who can do (or rather who usually does) whitelisting - the master or the peripheral device?
My findings so far:
I can't find a certain...
