I was looking for a system able to work with an iPhone (Bluetooth Low Emission – LBE) and a standard android (Standard bluetooth / rfcom). The RFDuino Arduino platform I have is perfect for BLE so, I decided to add a HC-05 module for the standard bluetooth.

 

Here is the description on how to make it !

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.

You can also get Apple tool : Bluetooth explorer and Packet Logger here.

Arduino and hc-05 bluetooth shield

Tonight, I start working on a third project I have in my hack list for the moment, this one is based on bluetooth and I order some arduino stuff to make it live. The arduino itself is a leonardo and the bluetooth is a hc-05 attached to a larger shield to be connected with arduino board directly.

This article details how to use HC-05 to transfer data between arduino &  mobile device based on Bluetooth. It includes HC05 source code for pairing and communicating.
