I know that there are a lot of restrictions on bluetooth when it comes to iOS. I wanted some more information on Bluetooth Low Energy (LE) and the CoreBluetooth Framework apple provides from iOS 5.0 and greater.
- Can i connect ANY Bluetooth LE device to an iOS device using the Core Bluetooth Framework?
- Is there any Bluetooth LE device in production,that comes with a three axis accelerometer and a gyro that i could use like a Human Interface device?
Sagar, Maybe you can explain more about what you want to do.
Any BT4.0 LE device can connect and communicate with a iOS app using the CoreBluetooth Framework.
The CC2540 dev kit does contain a fob that has accelerometer, it does not have a gyro.
The USB dongle that comes with the kit is for communicating with the fob from a PC/Mac, you do not need it for communicating with the iOS device.
