Abstract

Techniques that facilitate pairing of wireless devices with other wireless devices are disclosed. According to one aspect, a pair of wireless devices can be paired for wireless data exchange using an available wired link. Advantageously, the wired link can be used to transport a pin code from one of the wireless devices to the other. Consequently, pairing of the wireless devices can be completed without necessitating user entry of a pin code so long as the wired link is available.

Claims

1. A method for pairing a wireless device with a host device, the method comprising:

at the wireless device;

receiving a pairing request from the host device over a wireless network;

after detecting a wired connection between the wireless device and the host device,

waiting at least a pre-determined time period or until receiving a pin code from the host device over the wired connection;

when not receiving the pin code during the pre-determined time period,

presenting a pin code prompt screen to a user of the wireless device, and

receiving a pin code through a user input device of the wireless device;

after receiving the pin code,

generating authentication data based on the received pin code;

sending the authentication data from the wireless device to the host device; and

subsequently completing pairing of the wireless device with the host device when the wireless device has been authenticated.

2. The method as recited in claim 1, completing pairing comprises at least:

at the wireless device;

receiving one or more keys generated by the host device based on the authentication data from the wireless device when the pairing is successful.

3. The method as recited in claim 1, completing pairing comprises at least:

at the wireless device;

generating one or more keys; and

sending at least one of the one or more keys from the wireless device to the host device when the pairing is successful.

4. The method as recited in claim 2, wherein the one or more keys are received over the wireless network.

5. The method as recited in claim 3, wherein the at least one of the one or more keys are sent over the wireless network.

6. The method as recited in claim 2, wherein the one or more keys are received over the wireless connection.

7. The method as recited in claim 3, wherein the at least one of the one or more keys are sent over the wireless connection.
