When we pair two Bluetooth devices, the devices must authenticate each other to verify to which device a device is being paired. Bluetooth authentication may or may not be mutual depending on the application. At the time of authentication, one device initiates the authentication process and authenticates itself to the non-initing device. For mutual authentication, initially, the initiating device authenticates itself to the non-initiating device and then, the non-initiating device goes ahead and authenticates itself to the initiating device in the same way.

How does the Bluetooth authentication process work? In this article, we would discuss that in detail.
