Beacons integration with android via Bluetooth

The main focus of this integration is to detect measurements emitted by Multisense beacons for long periods of time (weeks) without interruptions. This project consists of a service that runs on the foreground by creating a notification. The service starts the BLE scanning process provided by the SDK and keeps it running even if the app is minimized or the mobile is locked. Operation and current problems: having 3 Android devices they work normally between 5 to 8 days, but at that time only in 1 of the 3 the measurement is interrupted, while in the other 2 devices it continues to operate normally.
Java programming is used.

Support is sought so that the measurement is not interrupted
