Communication between paired Bluetooth devices is not always immediate. This is because there are often several devices in the vicinity that are paired with a user’s device, and the user may need to go through a process of selecting one of the paired devices to route communications. This device selection procedure can be further complicated by the sometimes cryptic names assigned to the devices. Per the techniques of this disclosure, images of a Bluetooth accessory are captured at the time of pairing with a Bluetooth device. The user points a camera to the Bluetooth accessory to establish a communication path.
