Advanced Bluetooth Troubleshooting for Mobile Devices

Bluetooth connections are usually strong, but sometimes, signal or device interference can cause the connections to be dropped. This article will explain the steps to re-establish these connections when you're using your own mobile device.

Device Connection Failed is an error message that you might see on your phone or tablet when the Bluetooth connection to that device is no longer working.  This may affect your ability to upload your vital signs to the app.  There is a "Pair" link on the vital sign connections box in the app.  Activate pairing mode on the device and tap Pair.  

If trying to "Pair" the device from this screen does not resolve the issue, you may need to try to repair the connection.  

You can enter the vital signs manually if a connection fails.  Contact your care team if you would prefer to enter vital signs manually all the time.  

Repairing failed connections

Note that Bluetooth connections cannot be shared between multiple devices. This means that your blood pressure monitor cannot be paired to two tablets or a phone and a tablet at the same time.  If you are using a new device you must remove the Bluetooth connections from the old device before proceeding.  (See instructions here). 

Reboot your device

Power off your phone or tablet and then turn it back on again.  This may reset the connection to allow it to properly read from the device.  

If this does not work,

Choose the item you want to connect to, then SET THE DEVICE IN PAIRING MODE (see instructions here).  Then tap Scan.  


Find the device in the list of available Bluetooth devices.  

This might be difficult if you have a lot of Bluetooth devices as seen here.  If you are unsure which device to connect to, turn off the pairing request from the device and then turn it back on to see which device pops up on your screen.  This is most likely the device you are looking for.  
Each device may have a BT ID or MAC Address written on its label.  This can also help determine which device to pair to.  If one of those numbers matches something on this list, choose that one.

If your device is not showing up on the list, it may be paired to another device.  Power OFF any other tablets, mobile phones or computers while trying to connect to see if this helps.  See Forgetting Bluetooth devices for more information


There may be a second pairing confirmation that will pop up on the screen when you go to use the device.  Accept the Bluetooth pairing to complete the device configuration. 

How to place a device in Pairing Mode:

A&D BP Monitor:  Press and hold the start button until PR appears on the screen.

Nonin SPO2 monitor:  Place your finger in the device.  The Bluetooth symbol will appear on the screen.  Do not remove your finger until the pairing is complete.  

Fora IR20 Ear Thermometer:  Turn on the device and take your temperature.  Once completed, the device will be in pairing mode and the blue light will flash at the end of the handle.  

TNG SPO2 monitor:  Power on the device and place on a finger to get a reading.  Wait 5-10 seconds for the blue light to start flashing; this indicates that it is in pairing mode.  

How to Forget Bluetooth Devices

If you're moving your Bluetooth health monitoring devices from one phone or tablet to another, you will need to Forget this device on your original phone or tablet to release it so that it can pair to a new tablet or phone.

From the app screen, tap the Settings icon.  

Select Connections.  Tap Bluetooth. 

Be sure to tap the word Bluetooth and not the toggle switch.

 Tap the gear icon next to the device you want to remove and tap Forget or Unpair (device dependent).
