Connecting the Omron BP5250 Blood Pressure Cuff to Allie on Android


Allie features Bluetooth integration with Omron BP5250 blood pressure monitors. This guide provides best practices to ensure seamless transfer of blood pressure data from the blood pressure cuff to the AllieAllie Android application.

In order to pair the device, please make sure you have done the following during the installation process, completing all of the following:

    • Allowed Allie to turn Bluetooth on
    • Given Allie access to ""Location", Nearby Devices", and "Physical Activity"
    • Confirmed that Bluetooth is turned on for your phone

Note: If you have previously used a BP5250 to send blood pressure data to your phone via Bluetooth, you will need to delete any related applications. Then, go to your Bluetooth settings and "Forget" the previously connected device. We also recommend restarting your phone before proceeding with the pairing.

For best results, we recommend making sure that you are using the most recent versions of Allie and that your phone's operating system is up to date. More information on checking your settings/updating Allie can be found here.

You will also need to see an option for "Blood Pressure" in Allie. If you do not see this option, please check with your technician or Healthcare Provider to make sure they have set you up correctly.

Pairing Instructions

  1. Make sure the cuff is off. Then, open your Allie app, and go to "Settings" at the bottom right corner
  2. Select "Connected Devices"
  3. Then select "Blood Pressure Monitors"
  4. Select the "Omron BP5250" 
  5. This will take you to Step 1 - Press and hold the transfer or bluetooth button on your device for 3 - 5 seconds until you see a flashing P on the device screen
  6. Press and hold the button until you see the flashing "P" on your cuff. This indicates the cuff is in pairing mode
  7. Once the cuff is in pairing mode, tap "Continue" to be brought to Step 2 in Allie - You should see flashing pairing symbols "P" and are now ready to pair
  8. Tap "Continue" and when you go to the next screen, you'll see a "Pairing request" from your phone. Tap "Pair & connect" here, and then confirm you want to "Pair" in the next pop-up that displays.
    Note - depending on the type of phone, your pop-up may look slightly different. This is fine, simply confirm you wish to "Pair" to proceed to the next step
  9. The BP5250 should soon show 4 zeros, the "OK" icon, and the bluetooth symbol
  10. Shortly after, Allie will update to show you the "Success" screen. You can tap "Done" to leave pairing mode

This will return you to the "Connected Devices" screen and you'll see that the BP5250 is listed under "Blood Pressure Monitors". You may quickly see the text "Syncing", which will change to "Not connected" - this is expected.


You can tap the "Start/Stop" button on the cuff to turn it off now and proceed with your first reading.

Uploading Blood Pressure Readings to Allie

  1. When you are ready to take your blood pressure, open Allie and keep it open while you take your blood pressure
  2. Wrap the blood pressure cuff around your upper arm above the elbow
  3. Press the START/STOP button on the blood pressure monitor
  4. The blood pressure cuff will inflate and then deflate. You will see the numbers go up and then back down on the cuff. This process may take up to a minute to complete.
  5. When the cuff is finished, it will display your blood pressure and resting heart rate. 
  6. The reading will then be sent to Allie shortly afterwards (it may take a few seconds to synchronize). You will see an animation confirming "2 tasks completed" and the completed section will expand to show you the recent readings. There will be bluetooth icons indicating the reading came from a connected bluetooth device as well as checkmarks confirming these are completed tasks for the day

If your reading was outside of the normal range, you'll see a pop-up indicating that your reading was Low, Stage 1, Stage 2, or Crisis.


(The chart will also show you which range your top and bottom numbers belong to, as well as how "severe" they are for the range)

If the reading is also especially high (or low) for you, you'll see a "Next" option that provides more background on how this reading compares to your average reading for the last few days.


Allie will then prompt you to take another measurement to see if your levels have moved closer to your normal range. We recommend using the connected blood pressure cuff, but there will also be a "+" option to manually add a reading.


Allie will then indicate whether this reading is still high or closer to your normal range. You can now tap "OK" to return back to your Tasks page.


All the readings you have taken/added will be available shortly for your healthcare provider. You can wiat for the cuff to turn off, or turn it off by tapping the Start/Stop button.

If you are only expected to take your blood pressure once a day, you will not see any more blood pressure tasks for the day. However, if you take your blood pressure again later (making sure to keep Allie open), the new readings will be added to the "Completed" section. There will not be a check-mark for additional readings.


Please note: If you take your blood pressure but Allie is not currently open, the measurement may not show up in Allie. To address this, open up Allie and tap the Bluetooth button on the blood pressure cuff. This should send any recently saved readings from the cuff to Allie.
