How to capture ELA Beacon internal battery voltage?
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.
Note: only sensors that are v3.0 support this funcionality.
