BlueTooth BLE on iOS and Mac OsX

The RfDuino arduino device i’m actually hacking is a bluetooth 4 (BLE) device. I was expecting to work with it as any bluetooth devices in a terminal session like with rfcomm in previous version of bluetooth.

In fact not ! BLE are not pairable as the classical BT device, they are discovered by the application itself. Then you have communication channel you can read or write to communicate.

Thanks to a post in a forum, I’ve found a really usefull tool lightblue allowing to connect any BLE device and send it data. This soft works on iOS and MacOsX.
