Gadgetbridge is an Android application that supports many smartwatches and fitness trackers.
The integration of InfiniTime (previously Pinetime-JF) is now merged into the master branch (https://codeberg.org/Freeyourgadget/Gadgetbridge/) and initial support is available starting with version 0.47. Note that the official version is only available on F-Droid (as of May 2021), and the unofficial fork available on the Play Store is outdated and does not support Infinitime.
The following features are implemented:
- Scanning & detection of Pinetime-JF / InfiniTime
- Connection / disconnection
- Notifications
This video shows how to scan, connect, send notification (using the debug screen) and disconnect from the Pinetime.
