Update your Pulse App on your phone via the Apple or Google Play Store.
Turn on your Pulse and open the app. Connect over bluetooth and navigate to Settings > About > Update. If you firmware is not up to date, a popup will prompt you as well.
Keep the Pulse App open during the update, which will continue to 100% then flash the 'Successful Update' screen.
If your update gets stuck at 100%, fully exit the app, turn Pulse off then on, and restart the update.
The 'About' page should now look like the image below (Current App: v1.3.0.). If you are having problems reconnecting your Pulse after the firmware update, click here.
Having an Issue After Updating the App/Firmware?
We have seen that for some users, when the firmware update is performed the link keys between your phone and your Pulse can get messed up. What this means is that your phone will remember your Pulse, but the Pulse won't have the correct information to connect to the phone. Fortunately this is a quick thing to fix!
