Abstract

Methods, devices, and computer-readable media related to use of a scanner device and access node to repair a device-under-repair are disclosed. The first and second connections can utilize a first communication protocol (e.g., Ethernet or Bluetooth) and the third connection can utilize a different second communication protocol (e.g., OBD-II). In response to receiving a first communication addressed to a first address, the first communication can be sent from the scanner device via the second connection. In response to receiving a second communication addressed to a second address, where the first address differs from the second address, the second communication can be converted to conform to the second communication protocol and the converted second communication can be sent from the scanner device via the third connection.

Claims

1. A method, comprising:

at a scanner device, establishing at least a first connection, a second connection, and a third connection, wherein the first and second connections utilize a first communication protocol and the third connection utilizes a second communication protocol, and wherein the first communication protocol differs from the second communication protocol;

receiving, via the first connection, a first communication addressed to a first address;

in response to receiving the first communication addressed to the first address, sending, via the second connection, at least part of the first communication from the scanner device;

receiving, via the first connection, a second communication addressed to a second address, wherein the first address differs from the second address; and

in response to receiving the second communication addressed to the second address, converting the second communication to conform to the second communication protocol, and sending, via the third connection, the converted second communication from the scanner device.

2. The method of claim 1, wherein the first connection, second connection, and third connection are each wired connections.

3. The method of claim 1, wherein the first communication protocol is an IEEE 802.3 protocol.

4. The method of claim 1, wherein the second communication protocol is an On-Board Diagnostic (OBD) protocol.

5. The method of claim 1, further comprising:

receiving, via the second connection, a first-communication response to the first communication utilizing the first communication protocol; and

sending, via the first connection, at least part of the first-communication response utilizing the first communication protocol.

6. The method of claim 1, further comprising:

receiving, via the third connection, a message utilizing the second communication protocol;

converting the response to conform to the first communication protocol; and

sending, via the first connection, the converted response utilizing the first communication protocol.

7. The method of claim 1, further comprising:

establishing, at the scanner device, a fourth connection utilizing a third communication protocol, wherein the third communication protocol differs from the first communication protocol and the second communication protocol;

receiving, via the first connection, a third communication at the scanner device addressed to a third address, wherein the third address differs from the first address and the second address;

converting the third communication to conform to the third communication protocol; and

sending, via the fourth connection, the converted third communication utilizing the third communication protocol.

8. A scanner device, comprising:

a processor;

memory;

a communication interface; and

computer-readable program instructions, stored in the memory that, upon execution, cause the scanner device to perform functions, comprising;

establishing, via the communication interface, at least a first connection, a second connection, and a third connection, wherein the first and second connections utilize a first communication protocol and the third connection utilizes a second communication protocol, and wherein the first communication protocol differs from the second communication protocol;

receiving, via the first connection, a first communication addressed to a first address,

in response to receiving the first communication addressed to the first address, sending, via the second connection, at least part of the first communication,

receiving, via the first connection, a second communication addressed to a second address, wherein the first address differs from the second address, and

in response to receiving the second communication addressed to the second address, converting the second communication to conform to the second communication protocol, and sending, via the third connection, the converted second communication.

9. The scanner device of claim 8, wherein the communication interface comprises a wired interface, and wherein the first connection, second connection, and third connection are each wired connections.

10. The scanner device of claim 8, wherein the first communication protocol is an IEEE 802.3 protocol.

11. The scanner device of claim 8, wherein the second communication protocol is an On-Board Diagnostic (OBD) protocol.

12. The scanner device of claim 8, wherein the functions further comprise:

receiving, via the second connection, a first-communication response to the first communication utilizing the first communication protocol; and

sending, via the first connection, at least part of the first-communication response utilizing the first communication protocol.

13. The scanner device of claim 8, wherein the functions further comprise:

14. The scanner device of claim 8, wherein the functions further comprise:

establishing, via the communication interface, a fourth connection utilizing a third communication protocol, wherein the third communication protocol differs from the first communication protocol and the second communication protocol;

receiving, via the first connection, a third communication addressed to a third address, wherein the third address differs from the first address and the second address;

converting the response to conform to the third communication protocol; and

sending, via the fourth connection, the converted response utilizing the third communication protocol.

15. A computer-readable storage medium having instructions stored thereon that, upon execution by a processor of a device, cause the device to perform functions comprising:

establishing at least a first connection, a second connection, and a third connection, wherein the first and second connections utilize a first communication protocol and the third connection utilizes a second communication protocol, and wherein the first communication protocol differs from the second communication protocol;

receiving, via the first connection, a first communication addressed to a first address;

in response to receiving the first communication addressed to the first address, sending, via the second connection, at least part of the first communication from the scanner device;

receiving, via the first connection, a second communication addressed to a second address, wherein the first address differs from the second address; and

in response to receiving the second communication addressed to the second address, converting the second communication to conform to the second communication protocol, and sending, via the third connection, the converted second communication.

16. The computer-readable storage medium of claim 15, wherein the first connection, second connection, and third connection are each wired connections.
