BLE device like Heart Rate device can't be disconnected completely when GATT server is opened

[SayaSheng1]

Hi
Has anyone encountered this issue where a connected BLE device, such as a heart rate monitor, cannot be fully disconnected when a GATT server is running? The BluetoothManager.getConnectionState() function still returns CONNECTED, even though DISCONNECTED is received in BluetoothGattCallback.onConnectionStateChange(). Is there any impact when calling server.cancelConnection(device) in BluetoothGattServerCallback.onConnectionStateChange() after receiving the DISCONNECTED status?

BleServerManager.java

public void onConnectionStateChange(@NonNull final BluetoothDevice device, final int status, final int newState) {
			if (newState == BluetoothGatt.STATE_CONNECTED) {
				log(Log.INFO, "[Server] " + device.getAddress() + " is now connected");
				if (serverObserver != null)
					serverObserver.onDeviceConnectedToServer(device);
			} else if (newState == BluetoothGatt.STATE_DISCONNECTED) {
				if (status == BluetoothGatt.GATT_SUCCESS) {
					log(Log.INFO, "[Server] " + device.getAddress() + " is disconnected");
				} else {
					log(Log.WARN, "[Server] " + device.getAddress() + " has disconnected connected with status: " + status);
				}

				server.cancelConnection(device); // <- add this line

				final BleManagerHandler handler = getRequestHandler(device);
				if (handler != null && handler.bluetoothGatt == null) {
					// There is no client connection to the device.
					// We have to notify disconnection manually.
					handler.notifyDeviceDisconnected(device, status);
				}
				if (serverObserver != null)
					serverObserver.onDeviceDisconnectedFromServer(device);
			}
		}
