Ensure you use the latest version of Suunto app. Please check Play Store if there is an app update available and install it.
Open Suunto app on your phone and tap the ‘watch’ icon to enter the Watch view.
Suunto app will ask for the following permissions: a) Access to your location b) Excluding Suunto app from battery optimization for better app connectivity c) Enable notifications to be able to see the passkey notification, incoming calls and messages on your watch. Please ensure as well on your watch that notifications are enabled: Ambit3: Open Options menu > Connectivity > Settings > Notifications > On. Traverse: This option is only available after pairing your watch with Suunto app. Open Options menu > Connectivity > Notifications > On.
Start the pairing on your watch: Traverse: Open Options menu > Connectivity > Pair and select Mobile App. Ambit3: Open Options menu > Pair and select Mobile App.
When your Suunto watch appears in the list of watches tap PAIR. If more than one watch is listed, select your watch based on the serial number shown at the backside of your watch.
Enter the passkey shown on your watch into the pairing request field on your mobile device and tap PAIR.
Wait for the pairing to complete. This may take a moment.
Suunto app will automatically start synchronizing your workouts and optimizing your watch’s GPS. This may take several minutes up to several hours depending on the amount of un-synced logs on your watch. Note: After a few minutes of inactivity, your Ambit3 / Traverse will activate the power saving mode which will turn off Bluetooth and pause the sync. The log synchronization will continue once you wake up your watch.
