iPhone 4S says goodbye to MFi for Bluetooth Smart Devices

TI BLE CC2540 iOS app

Big news from Texas Instruments, they’ve just released a video demonstrating the keyfob included in the CC2540DK-MINI dev kit communicating with the Iphone 4S using the GATT interface through the new Core Bluetooth API.

This is a particularly big deal because it shows the CC2540 interacting with the iPhone 4S using the stock 2540 mini dev kit without an authentication chip.
