Battery Level Reporting
The remote supports the standard Bluetooth LE Battery Service. After connection, the battery level is updated once per second for
approximately 30 seconds. After that, the remote refreshes the battery level by sampling once per second for 10 seconds every 5 minutes.
When connected, pressing Button 1 can trigger an immediate 10-second battery refresh. Repeated button-triggered refreshes are locked for
60 seconds to reduce power consumption.
