I want to get the RSSI value of a BluetoothLEDevice which has already been connected by my program. So BluetoothLEAdvertisementWatcher doesn't work because the device no longer advertise after connected.
I have also tried DeviceInformation.Properties["System.Devices.Aep.SignalStrength"] but the value never update. Is there any way to get the current RSSI value of a connected BluetoothLEDevice?
