I am looking for an arduino board able to communicate through both wifi and bluetooth 4.0. Is there a specific arduino model available? I would like to design some kind of BLE Gateway able to scan and broadcast information via BLE to Bluetooth devices like compatible mobile phone.
I have found this piece of hardware: http://www.geeetech.com/wiki/index.php/Arduino_Bluetooth_Low_Energy_%28BLE%29_Shield. But I read it only supports Peripheral (Slave) role operation so I am not sure it would fit the kind of purpose I am looking for.
