Children Control Solution
This is a smart watch for kids with a custom launcher. It allows parents to be always in touch with their children, but at the same time to limit functionality for them. It has an exciting and fun design.
Custom BLE protocol has been developed for the pairing process and first initialization of the device. In this way, all necessary information comes to the watch from the parent's application (time, user’s data, data for initialization in the system) after appropriate settings.
The task from the client has been to develop the game, during which the watch would find friends nearby. After the agreement of two friends, the playback of the song should start simultaneously in order to create the duet. Due to some peculiarities of working with Bluetooth, the team tested various options of solving the problem and, eventually, applied the one that minimizes the sound delay.
