General Information
First thing you have to know before configuring a sensor is data protocol. For detailed ELA description about Bluetooth frame specifications please refer here.
To enable internal battery voltage in the scan response frame, battery voltage presence must be configured in the NFC memory using ELA's Device Manager Mobile application.
For more detailed information about Advanced Beacon Capturing Configuration please refer here.
In Scan Response frame, bytes 6 and 7 are listed as LSB and MSB, meaning that byte 7 should be calculated first and byte 6 second. Example: AC0B ->0BAC; 0BAC(hex) -> 2988(dec)*0.001 multiplier. Gives 2.988V internal battery voltage.
Note: only sensors that are v3.0 support this functionality.

Version 3.
Battery voltage presence has to be configured to value 1.
