Settings in Allie

First, please make sure that you are using the most up-to-date version of Allie. We recommend turning on Auto Update for Allie (more details here). You can also force an update at any time by following these instructions.

If you are still having issues with connecting to devices, please check all of the following settings. These are generally set up during the initial installation of Allie:

  • Ensure that Bluetooth is turned ON
  • You can also go to "Permissions" and then "System Authorization" in Allie

  • Bluetooth should be enabled
  • Tap into "Notifications" to make sure that Allie is set to "Allow Notifications"
  • Make sure that Allie has read/write permissions for Apple Health. To do this, open up Apple Health and tap your profile icon at the top-right, then scroll down to "Apps", and select "Allie". Make sure that all of the options are enabled:

We also recommend making sure you are using the most recent version of your phone's operating system. This can be checked/updated by going to Settings --> General, and then "Software Update".


We recommend having Automatic Updates "On". You will see your current iOS version and whether there are pending updates below.



Pairing Issues - General

Readings Not Sent to Allie

If you have successfully paired the your bluetooth device and seeing the readings on the device but NOT on your phone, please first make sure that the Allie application is open whenever you take a reading.

If you've taken readings previously that are not visible in Allie, those readings should be sent to Allie the next time the devices synchronizes with the Allie application.

Additionally, if readings from your bluetooth device are not showing up in Allie, please double-check that the time of your device is accurate. If the time of your device is too far ahead of the time on your phone, this could cause delays with the synchronization process.

Pairing Issues

You can also check the status of the paired device at any time by going to the "Connected Devices" screen in Allie and choosing your device type.

Any paired devices should be listed, along with the model ID. If the device is turned on, you should see a blue checkmark indicating the device is currently connected. 


If the status for all of your devices is instead "No device paired", that indicates that there are no devices currently paired, so you will want to try the pairing process from the beginning.


If you are still having difficulty, try going to to Settings on your phone and then tap the "Bluetooth" option. 

If you see the device listed under "My Devices" and "Not Connected" in your phone's Bluetooth settings, please do the following:

  • Tap the name of the device
  • Choose "Forget This Device" and then confirm you want to "Forget Device" below
  • Now try the pairing process again from the beginning

If you do not see your device listed below "My Devices", you can try the pairing process again.

Unpair and Re-pair the Devices

In some cases, you may want to reset the pairing between your phone and your device. To do so, go to the Settings menu, then select "Connected Devices", and tap into the type of device you wish to re-pair.


Tap on the paired device to be brought to the un-pairing screen:


Tap "Unpair" at the bottom and then "Unpair" in the pop-up to complete the process in Allie.


Then go to your phone's Bluetooth settings. The device will likely still be listed there. Follow these steps:

  • Tap the name of the device
  • Choose "Forget This Device" and then confirm you want to "Forget Device" below

Then try re-pairing the device from the beginning. 

Issues with Glucometers

The most common issue with glucometers is not seeing your reading in Allie immediately after taking it. Please note that it could take a minute or two for your reading to synchronize.

In many cases, you can also try turning the glucometer off and on again to force a synchronization. If this does not resolve your issue, please read on for more details.

Contour Next One

Cannot Take a Blood Glucose Reading

When you add your blood (or the control solution) to a strip that is inserted into the Contour, you should see a screen prompting you to add a small drop of blood to the strip.


In some cases, the amount of blood may be insufficient, in which case you'll see the following:


This indicates you need to add another drop of blood until you see the countdown which confirms the Contour is measuring your glucose levels. If you do not add enough blood within a minute, you'll see an indication to try again with a new strip.


Additionally, if you see an E2 code when inserting the strip, this indicates there is an issue with the strip you've used.


Simply try another strip and you should be prompted you for a reading.

Issues with the Omron SC-150 Scale

Check Scale Display

When you take your weight with the scale, please make sure you are seeing your weight flash when it has been stable. You should also see the bluetooth symbol along with your weight:


If you do not see the bluetooth symbol, please wait for the screen to go blank and try taking your weight again. If issues continue, you can try resetting the scale:

Reset the Scale

If the general troubleshooting steps above are not resolving your issues with the Omron SC-150 scale, you can reset it at any time. First, we recommend unpairing the scale in Allie, and then confirming that the scale is not listed as a previously connected device on your phone.

Then, hold the bluetooth button on the scale down for at least 2 seconds until you see the flashing "P" and bluetooth symbol, then release


Now, hold the bluetooth button down for at least 5 more seconds until you see the "CLr" screen and the bluetooth symbol stops flashing.


Then turn the scale over and press the "Set" button. When the display stops flashing, the scale has been reset.

The scale will then turn off after about 10 seconds, and you can start the pairing process again from the beginning

Issues with the Omron Blood Pressure Cuffs (HEM-9200/9210 & BP5250)

There are slight differences between the Omron Blood Pressure cuffs, but generally speaking they all work similarly and display the same error messages.

Error Messages

The Blood Pressure cuff may display error messages if it is unable to take a reading. You can consult the owners manual for more details on each message, but here are the most common ones:

E1 - indicates there is either an issue with the air plug, cuff, or that the cuff is not tight enough. Please check your connections and try again.

E2 - indicates that there was too much movement during the reading. Please try taking a measurement again and remain as still as possible until the cuff has finished the process.

Synchronization Issues

BP5250: The consumer Blood Pressure cuff has a single bluetooth/connectivity icon that indicates whether the readings are being sent to Allie:


If you do not see this symbol, that likely means there is an issue with synchronization. Please check to make sure the cuff is currently paired following the instructions above.

You can also force a synchronization with the BP5250 by pressing the Bluetooth/connection button:


HEM 9200/9210-T: The commercial Omron Blood Pressure cuffs have two bluetooth symbols that are displayed to indicate whether the data is being sent from the cuff to Allie. In this picture, the image at the top-left indicates the reading was successful. You will see the values in Allie after this image disappears (the measurement will remain on the screen until you turn it off):


If you do not see this symbol, and instead see the one to the right, that indicates the reading will not be sent to Allie:


If you continue to see this symbol when taking your blood pressure, please try pairing the cuff again.

Re-pairing the Blood Pressure Cuff

BP5250: After un-pairing the cuff (more details above), try the pairing process again by starting at Step 1 and pressing the bluetooth button for 3-5 seconds to put the cuff in pairing mode. Then follow the steps to re-pair the cuff and try taking another measurement.

HEM-9200 / 9210-T: This cuff requires an additional step to reset the pairing process. After un-pairing the cuff (more details above), take one of the batteries out of the cuff and then tap the "Start/Stop" button on the cuff 3 - 4 times.

Then open Allie and start the pairing process again by starting at Step 1. Re-insert the battery into the cuff to see the flashing "P" symbol indicating the cuff is in pairing mode. Then follow the steps to re-pair the cuff and try taking another measurement.
