Connect Hedia Diabetes Assistant (HDA) to your NFC or Bluetooth Glucose Meter

Hedia’s aim is always to make each step of diabetes management simpler: have your numbers added automatically by connecting your blood glucose meter to HDA.

We’ve cooperated with GlucoMen Areo, Areo2K, and CONTOUR® NEXT ONE – as well as currently developing compatibility with Beurer GL50 evo and NovoPen Echo – to bring you in-app Bluetooth or NFC connection with your blood glucose meter.

Find out how to connect in the guide below.

Wireless Blood Glucose Readings
HDA lets you add your numbers swiftly and simply

Recording the numbers from your blood glucose meter shouldn’t have to be a chore. While HDA makes it easier to record your numbers, it can be even easier when the numbers are added to the app for you!

This means that whenever you want an insulin calculation from HDA, you connect your NFC or Bluetooth glucose meter with HDA. Then, your blood glucose level is automatically included in HDA’s calculation for your insulin dosage.

Setting up: Prepare your Devices

Activate NFC or Bluetooth on your smartphone

For Apple phones, NFC is enabled as the default setting. To use Bluetooth with iOS, read more here.

Activate the wireless functions on your blood glucose meter

With some blood glucose meters, you might need to check if the glucometer Bluetooth or NFC has been activated. Check the user manual of your blood glucose meter for more information.

Make sure that your blood glucose meter has the correct time and date

To ensure blood glucose meter app compatibility, the time and date of each device should match. Since smartphones usually automatically have the correct time and date, you should check that your blood glucose meter also has the correct information too.

Again, see your NFC or Bluetooth glucose meter’s manual for more information on how to change the time.

Where to get more Information on the NFC or Bluetooth Glucose Meter

Are you unsure what exactly Bluetooth and NFC do?

Bluetooth or NFC are methods for connecting devices wirelessly. Bluetooth is a way for devices to connect within usually at least ten metres without wires. Meanwhile, NFC (near-field communication) connects via scanning a chip, which means your devices need to be within 4cm of each other.

If you need more information on connecting a glucometer Bluetooth or NFC device with HDA, read our pages specifically about connecting HDA with either CONTOUR® NEXT ONE or Glucomen Areo and Glucomen Areo 2K.
