BLE сканер с ожидаемыми намерениями не обеспечивает сканирования ⇐ Android

[Anonymous]

Попытка использовать startScan с ожидаемыми намерениями. Транслярный приемник вызывается, однако при условии, что при условии не имеет никаких дополнений (и не имеет никакого результата сканирования к намерению). Этот код работал нормально в старой версии Android.fun ComponentActivity.startScanner() {
if (!checkForPermission(
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.S){
Manifest.permission.ACCESS_COARSE_LOCATION
}
else {
Manifest.permission.BLUETOOTH_SCAN
}
)){
return
}

with(logViewModel) {
if (!haveBtPermissions) {
haveBtPermissions = true
clear()
}
}

// bluetoothAdapter.bluetoothLeScanner.startScan(filters, settings, scanCallback)
bluetoothAdapter.bluetoothLeScanner.startScan(filters, settings, pendingIntent)
Log.i(TAG, "Scanner started")
}

private val filters get() = mutableListOf().apply {
val filterShortServiceUUID = ScanFilter.Builder()
.setServiceUuid(ParcelUuid.fromString ("0000${"180D"}-0000-1000-8000-00805F9B34FB"))
.build()
add(filterShortServiceUUID)
}

private val settings get() = ScanSettings.Builder().setScanMode(
ScanSettings.SCAN_MODE_BALANCED
).build()

private val ComponentActivity.bluetoothAdapter get() = (applicationContext
.getSystemService(ComponentActivity.BLUETOOTH_SERVICE) as BluetoothManager).adapter

private val ComponentActivity.pendingIntent get() =
applicationContext.let {appContext ->
val intent = Intent(appContext, DeviceBroadcastReceiver::class.java)
// .setAction("com.solvek.bletrigger.ACTION_FOUND")

PendingIntent.getBroadcast(
appContext, 0, intent,
PendingIntent.FLAG_UPDATE_CURRENT or FLAG_IMMUTABLE
)!!
}

private fun ComponentActivity.checkForPermission(permission: String): Boolean {
if (ActivityCompat.checkSelfPermission(
this,
permission
) == PackageManager.PERMISSION_GRANTED
) {
return true
}

with(logViewModel) {
append("Please grant permissions and restart app!")
haveBtPermissions = false
}

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S){
registerForActivityResult(ActivityResultContracts.RequestMultiplePermissions()){
startScanner()
}.launch(arrayOf(
Manifest.permission.BLUETOOTH_SCAN,
Manifest.permission.BLUETOOTH_CONNECT
))
}

return false
}
