Thanks @Gordon. I guess I'm confused -- since it was an NRF function, I was assuming that it was the battery level of a remote connection, which over Bluetooth is expressed as percentage. Is this the battery voltage of the local system? In other words, an A/D reading from an input connected to the battery? If so, it would be good to document it a bit better to avoid future confusion. Thanks! Bill
