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?
Sorry, there is no way currently to get connected RSSI on Windows. We are aware of the request by developers to implement connected RSSI, however it's not currently implemented and still in our backlog.
