How to upgrade your Eversense Smart
Transmitter

Get Ready First (Before You Upgrade)

Before you upgrade the firmware on your Smart Transmitter using the Eversense 365 App, you need to do a few important things. These steps will help make sure the upgrade goes smoothly:

  • Check for Eversense 365 App Updates: Open your app store and check if there’s a new version of the Eversense 365 App. If there is, download it.
  • Charge Your Transmitter: Make sure your Smart Transmitter is fully charged before you start the upgrade.
  • Choose a Convenient Time: Upgrading can put your system into the Initialization Phase, which requires four fingerstick calibrations.

NOTE: After Initialization, your system will return to the calibration phase it was in before the upgrade.

Upgrade the Firmware in your Smart Transmitter

Upgrade Notification: When a firmware upgrade is available for your transmitter, you will receive an Upgrade Available Notification on your app.

STEP 1:

  • To begin the firmware upgrade, tap Next.
  • If you are unable to upgrade at this time, tap Not Now.
  • You will be reminded of your upgrade periodically but you are able to access the firmware upgrade when you are ready.
    • Go to the Main Menu > About > My Transmitter

STEP 2:

  • The system will display the new firmware version when the upgrade is ready to install.
  • Tap Continue when prompted.

The system may not be able to begin the firmware upgrade if the transmitter battery is too low, a calibration is in progress, or if the transmitter is disconnected.

STEP 3:

  • Review the changes in the upgraded transmitter version.
  • Check the box to confirm you have reviewed and understand the changes.
  • Tap Start Upgrade.
    • DO NOT turn off your transmitter, move away from your phone or close the app during this time.
    • You will see a progress bar while the upgrade is taking place.
    • During the upgrade process the transmitter will reconnect automatically.
  • Once the upgrade is complete, tap OK.

NOTE: If your transmitter does not automatically reconnect, see Next Section TRANSMITTER RECONNECT

Transmitter Reconnect

During some upgrades, you may be prompted to reconnect your transmitter.

IMPORTANT: Before reconnecting, FORGET the transmitter from your device’s Bluetooth settings

STEP 1:

When prompted, tap Reconnect Transmitter.

STEP 2:

  • With the smart transmitter turned on, press the soft touch button three times to start pairing mode.
    • The LED will blink blue to indicate the smart transmitter is in pairing mode.

NOTE: Your mobile device must be connected to the internet in order to pair with the smart transmitter.

  • On the Connect screen, tap your smart transmitter serial number.
    • Your smart transmitter serial number can be found on the back of the smart transmitter.
