Abstract

In one embodiment, a method comprising without user intervention: receiving encrypted first information from a device over a wired medium; decrypting the encrypted first information; and communicating second information over a wireless medium based on the first information.

Claims

1. A method, comprising:

without user intervention;

receiving encrypted first information from a device over a wired medium;

decrypting the encrypted first information; and

communicating second information over a wireless medium based on the first information.

2. The method of claim 1, further comprising communicating wireless connection capabilities over the wired medium.

3. The method of claim 2, wherein the communicating of the wireless connection capabilities is responsive to powering up and being connected to the wired medium.

4. The method of claim 1, wherein the first information comprises network settings and connection credentials.

5. The method of claim 1, wherein communicating the second information over a wireless medium comprises communicating the second information to the device.

6. The method of claim 1, wherein communicating the second information over a wireless medium comprises communicating the second information to a remotely located device that is not connected to the wired medium.

7. The method of claim 1, wherein receiving the encrypted first information comprises receiving broadcasted encrypted first information that is received by at least one other device.

8. The method of claim 1, wherein the receiving, decrypting, and communicating occur on a mobile machine or an implement coupled to the mobile machine.

9. The method of claim 1, wherein the receiving, decrypting, and communicating occur in an ad hoc mode.

10. The method of claim 1, wherein the receiving, decrypting, and communicating occur in an access point (AP) mode.

11. The method of claim 1, wherein the wired medium comprises multiple physical wiring logically configured as a controller area network (CAN) bus or CAN busses.

12. A method, comprising:

without user intervention;

sending encrypted first information over a wired medium; and

communicating wirelessly with a device connected to the wired medium based on the sending of the encrypted first information.

13. The method of claim 12, wherein the device is connected to the wired medium, the wired medium comprising multiple physical wiring logically configured as a controller area network (CAN) bus or CAN busses.

14. The method of claim 13, further comprising additional devices connected to the wired medium, the additional devices receiving the encrypted first information, wherein the communicating comprises communicating wirelessly with the additional devices based on the sending of the encrypted first information.

15. The method of claim 14, wherein the sending and the communicating occur on a mobile machine, an implement coupled to the mobile machine, or a combination of the mobile machine and the implement.

16. The method of claim 12, further comprising communicating wireless connection capabilities over the wired medium, wherein the communicating of the wireless connection capabilities is responsive to powering up and being connected to the wired medium.

17. The method of claim 12, wherein the first information comprises network settings and connection credentials.

18. The method of claim 12, further comprising wirelessly communicating with a remotely located device, wherein sending the encrypted first information comprises sending network settings and connection credentials of the remotely located device.

19. A system, comprising:

a mobile machine, comprising;

a wired medium; and

a first device coupled to the wired medium, the first device comprising;

a processor configured to automatically establish wireless communications with one or more other devices coupled to the wired medium based on an exchange of information, without user intervention, with the one or more other devices over the wired medium.

20. The system of claim 19, further comprising a second device located remotely from the mobile machine and un-connected to the wired medium, wherein the one or more other devices are configured to establish wireless communications with the second device based on the exchange of information.
