Problem with writing characteristics on background mode

[Loovery]

Version

• react-native-ble-manager v7.1.4
• react-native v0.63.2
• Android v.10

Expected behaviour

Writing data into the characteristic, in the background mode

BleManager.write(id, service, characteristic, data);

Actual behaviour

Nothing happens, not even an error

Steps to reproduce

1. Connect to the device.
2. Check that everything works in the active mode.
3. Changes take place every 5 seconds
4. Send the application to the background mode (background-timer is started for recording every 5 seconds).
5. Data is sent to the record, but nothing changes.

AndroidManifest:

<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

PermissionsAndroid check

PermissionsAndroid.check(PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION) - true
PermissionsAndroid.check(PermissionsAndroid.PERMISSIONS.ACCESS_BACKGROUND_LOCATION) - true

Question

What am I doing wrong? How do I send the write in the background correctly?
On iOS works perfectly
