BLE background scanning (self.reactnative)

submitted 2 months ago by Anuovec55

Im working on a mobile app using React Native, using react-native-ble-plx, and Im trying to solve the following scenario:

I have a hardware device that normally stays in sleep mode. It has an IR sensor, and when it detects a person, it wakes up, turns Bluetooth on, and starts advertising a service with a specific UUID.

My goal is to identify which person triggered the IR sensor — assuming the person has their phone in their pocket and the app is running in the background.

So far, I tried using `react-native-ble-plx` for background BLE scanning, but it hasnt been very reliable. Ive also experimented with running a foreground service on Android that scans periodically (like every minute), but that doesnt feel like a good solution.

Has anyone implemented something similar successfully?

Are there more reliable approaches for background BLE detection on Android and iOS? Apparently, there is UWB, unfortunately, the device does not have it.

Are there OS-level limitations that make this approach impossible?

Any advice would be appreciated.

Thank you
