There is a high probability that the LibreLink app or the Reader creates a new private shared key for communication during the connection. What is going on? When a Bluetooth connection is made a private shared key is created that is needed to allow communication between the sensor and the calling application/device. I am not sure if LL needs to be disabled each time but I disable it to be on the safe side. However between these BT readings I have not had any problems executing an NFC scan followed by immediately disabling the app. If you catch it at the wrong time it will disturb the BT process in xDrip+ and not receive BT readings, which can take a while to rebond and transmit again and sometimes a sensor BT connection can be “stolen” by LibreLink. 4 minutes ago), if it is near 5 min, wait for the new BT reading to come in and then conduct the NFC scan. Always look at xDrip+ and see if it is close to the 5 minute reading (ie. Using LibreLink NFC Scans AFTER bonding/pairing in xDrip+ is completed: You can conduct NFC scans but the bonding/pairing process with xDrip+ needs to be completed first. After pressing Test for xBridgePlus protocol you should see this field update however, the data may not change a the request is the same each time. Send Data: This is the data request hexadecimal stream sent to the sensor to start data retrieval. The data should change after pressing Test for xBridgePlus protocol. If you see characters here then you are actively receiving data from the sensor. Received Data: This is a hexadecimal representation of the data stream coming from your sensor. Pressing Test for xBridgePlus protocol you can manually start a request for data from your sensor. Request Data: Only shown with Engineering Mode enabled in xDrip+. The GATT and Device Address should match for your sensor hardware ID. Any bluetooth devices actively bonded to your phone will display their hardware ID here. GATT device connected: This is the hardware ID registered in the Android BT service. True means the sensor is connected and bonded.ĭevice Mac Address: This is the hardware ID of the sensor Phone Service State: The last time the phone made a BT connection to the sensorīluetooth Device: Displays current status of the connection (either Connected or Disconnected)Īctive device connection: Displays the status of the bluetooth bond after connection.
