Customer didn’t want iSantaCam app to have high-end user interface. Their focus for the initial version of the app was to deliver the functionality quickly to test the market for iSantaCam devices. Mobile application required using Bluetooth to interface with the LED peripheral device. For this project we had to work in conjunction with the device manufacturer based in China. They had defined a protocol for transferring data over Bluetooth. One of our developers, natively from China, became an asset for this project. He served as a translator and helped customer communicate with the device manufacturer. That greatly helped us building interface between iOS app using Core Bluetooth framework and custom protocol on the peripheral LED device. Mobile app included capability to detect nearby iSantaCam devices and allowing parents to send message to a selected iSantaCam device.
