BLE на Android – получите UUID ближайших устройств ⇐ Android

[Anonymous]

I am creating an app that through a ble scan returns a list of nearby devices, each device is an object which contains two pieces of information:

• UUID : String,
• rssi: Int

I can get the rssi value and device address but I can't figure out how to get the uuid. I can't find explanations on the basic code to implement and most of the answers are on Java code, which is not very easy to adapt into kotlin, at least for me.

I tried this way, but I don't know if I'm doing it right or if I'm completely off track for what I would like to achieve

Scan Settings:

private val scanSettings = ScanSettings.Builder() .setScanMode(ScanSettings.SCAN_MODE_LOW_LATENCY) .build()` Scan Callback

private val scanCallback = object : ScanCallback() { @SuppressLint("MissingPermission") override fun onScanResult(callbackType: Int, result: ScanResult) { val listUUID = result.scanRecord?.serviceUuids if(listUUID != null){ val parcelUuid = listUUID[0] val device = Device(devUUID = parcelUuid.uuid.toString(), rssi = result.rssi) listDevice.add(device) } override fun onScanFailed(errorCode: Int) { Log.e("ScanCallback", "onScanFailed: code $errorCode") } } To start the scan bleScan.startScan(null, scanSettings, scanCallback)
