CurieBLE receive data without pairing
HC-05 module is not BLE (Bluetooth 4.0)! HC-05 implements SPP (Serial port profile) over Bluetooth Classic (Bluetooth 2.0). You will need a module with BLE capability and that is not over yet. BLE implements several (hundred) profiles for each task such as heartrate monitor, neuro monitor, time etc etc. Your BLE module must be condigured to receive a specific profile data.
