VaiKai SmartPlay Doll

In a nutshell

This project aimed to enable the VaiKai product to be a smart toy using BLE technology. needCode employees added BLE functions to the existing client software project. They also updated the existing implementation to support all required BLE functions. The scope of work included most of the features associated with FW or v0.1 and v0.2 from Vai Kai Companions – interaction specifications and user stories.

Transforming VaiKai into a modern smart toy was a mission undertaken by the visionary needCode team. Leveraging BLE technology, the team elevated the VaiKai product by enhancing client software, integrating crucial BLE functionalities, and aligning with the latest requirements.
