A BLE-enabled wearable accessory with smart capabilities
Smart jewelry bracelet
T&M (time and materials)
Softeq implemented a smart solution consisting of firmware and mobile apps for iOS and Android devices to underlie the luxury wearable accessory. The team also created production tools to ensure product integrity in mass production.
Softeq helped the client to implement a smart solution, developing firmware and apps for Android and iOS devices.
The customer turned to Softeq to create firmware for the smart bracelet and pair the device to a smartphone. The bracelet needed to allow women to monitor their physical activity and notify a pre-approved list of contacts in an emergency.
The bracelet is complete with real-time notifications, distress messaging, a pedometer, and detailed activity tracking.
The safety function can send a distress signal to a pre-approved list of contacts, along with optional geolocation and sound recording of surroundings. It is possible to manage a list of pre-approved contacts, vibration patterns, touch patterns, types of notifications, and more on the Socialite app.
The firmware establishes a secure two-way connection between a smartphone and the bracelet via BLE while keeping power consumption to a minimum. This allows the bracelet to:
The solution leverages the security capabilities implemented within the BLE technology—BLE GATT. The device can establish exclusive connections, meaning the BLE peripheral can only be connected to one central device (a mobile phone, etc.) at a time.
To enable the desired functionality, our team had to solve several technology challenges.
We used a VoIP service to enable emergency messaging, as iOS doesn’t allow direct access to a user’s contact list.
Originally, the bracelet hardware had some issues, which limited functionality and made mass production impossible. Softeq improved the schematics to support all project requirements for the mass market.
Softeq adapted the solution for unstable BLE on Android (OS v4.2, 5.1).
We improved the accuracy of the pedometer algorithm.
We reduced false responses to the distress activating algorithm, when tapping the bracelet, and added the bracelet training.
As the hardware and firmware didn’t support the firmware update, we enabled the simultaneous update of the mobile app and firmware.
The resulting solution demonstrated smart capabilities, transmitting BLE through metal five times further than conventional Bluetooth. Further plans included integrating the smart solution with Google Fit and Apple Health Kit to enable users to track their health and fitness data aggregated from multiple apps.
