hai
i am using a ble embedded arduino board with cc2540 ble chip. now i need to know some details.
in my project i need to connect a central device to cc2540 and write some values in characteristics. and the arduino will take actions according to the data written in characteristics. so if there is no any bonding between central device and the cc2540. any one can connect to cc2540 and can write in characteristics. so inorder to provide security i would like to allow connections to a trusted central devices only . so how can i make a bonding between cc2540 and central. the processor in my board communicate with cc2540 through AT commands. so have any AT command for the above problem.......?
ThankYou
