It is 5 seconds to measure the current when only SX1268 sleeps
.
I’d try putting a delay between radio.begin() and radio.sleep() maybe the radio is in an indeterminate state when sleep() is called?
Putting delay() has no effect.
I will do some more research.
EDIT:
Since the current of radio is as small as 1 mA compared to the 30 mA of S3 current, the current just seemed to change very little when
radio.sleep() was executed.
