Abstract

A mobile computing device (MCD) can determine, based on model-specific test result information, whether an accessory may be incompatible with specific MCD functions. In some embodiments, the accessory provides test result information separately indicating a test result for each of a number of MCD models. Multiple MCD models can be grouped into a device class, and the MCD can deem the accessory compatible if he received test result information indicates a pass result for at least one of the device models associated with a device class to which the MCD belongs. If the accessory is not deemed to be compatible with the mobile computing device, the MCD can generate a warning.

determining, by the mobile computing device, whether the accessory is deemed to be compatible with the mobile computing device, wherein the determination is based at least in part on whether the received test result information indicates a pass result for at least one of the device models associated with the target device class; and

generating, by the mobile computing device, a warning in the event that the accessory is not deemed to be compatible with the mobile computing device.

2. The method of claim 1 further comprising:

receiving, by the mobile computing device, waiver information from the accessory, the waiver information indicating whether testing was waived for one or more of the predefined device classes, and

wherein the determination whether the accessory is deemed to be compatible with the mobile computing device is based in part on whether testing was waived for at least one of the device models associated with the target device class.

3. The method of claim 1 wherein receiving the test result information includes receiving a bit mask wherein each bit corresponds to a different device model and wherein determining whether the accessory is deemed to be compatible with the mobile computing device includes accessing bits from the bit mask that correspond to device models in the target device class.

4. The method of claim 1 further comprising:

displaying, by the mobile computing device, an accessory information screen for the user, the accessory information screen including at least a portion of the test result information.

5. The method of claim 1 wherein the test result information reflects a result of a radio-frequency interference test.

6. The method of claim 1 wherein generating the warning includes displaying a pop-up message on a display of the mobile computing device.

7. The method of claim 1 wherein generating the warning includes providing warning information in an accessory information screen displayable on the mobile communication device, the warning information indicating that the accessory is not deemed to be compatible with the mobile computing device.

8. A computer readable storage medium encoded with program instructions that, when executed, cause a processor in a target mobile computing device to execute a method, the method comprising:

receiving a test result bitmask from an accessory, the test result bitmask consisting of a plurality of bits, each bit being associated with a different one of a plurality of mobile computing device models, each bit indicating whether the accessory passed a compatibility test with the associated mobile computing device model;

selecting one or more bits from the test result bitmask, wherein each of the selected one or more bits is associated with a mobile computing device model belonging to a same device class as the target mobile computing device;

determining, based at least in part on the selected one or more bits, whether the accessory passed the compatibility test with at least one mobile computing device model belonging to the same device class as the target mobile computing device; and

generating a warning in the event that the accessory did not pass the compatibility test with any mobile computing device model belonging to the same device class as the target mobile computing device.

9. The computer readable storage medium of claim 8 wherein the method further comprises:

receiving a waiver bitmask from the accessory, the waiver bitmask consisting of a plurality of bits, each bit being associated with a different one of the plurality of mobile computing device models, each bit indicating whether the compatibility test was waived for the accessory with respect to the associated mobile computing device model, and

wherein the determination as to whether the accessory passed the compatibility test with at least one mobile computing device model belonging to the same device class as the target mobile computing device is based in part on the waiver bitmask.

10. The computer readable storage medium of claim 8 wherein generating the alert includes prompting the user to disable a feature of the mobile computing device.

11. The computer readable storage medium of claim 8 wherein the plurality of device models includes at least one mobile phone model and at least one tablet computer model.

12. A mobile computing device comprising:

a processor;

an accessory interface communicably coupled to the processor and configured to communicate with an accessory; and

a storage device configured to store data including one or more mobile computing device model identifiers associated with a target device class,

wherein the processor is configured to;

receive a test result bitmask about the accessory, the test result bitmask consisting of a plurality of bits, each bit being associated with a different one of a plurality of mobile computing device models, each bit indicating whether the accessory passed a compatibility test with the associated mobile computing device model;

receive a waiver bitmask about the accessory, the waiver bitmask consisting of a plurality of bits, each bit being associated with a different one of the plurality of mobile computing device models, each bit indicating whether the compatibility test was waived for the accessory with respect to the associated mobile computing device model;

determine, based on the test result bitmask, whether the accessory passed the compatibility test with at least one mobile computing device model belonging to the same device class as the target mobile computing device;

determine, in the event that the accessory did not pass the compatibility test with any mobile computing device model belonging to the same device class as the target mobile computing device, whether the waiver bitmask indicates that the compatibility test was waived for the accessory with respect to at least one mobile computing device model belonging to the same device class as the target mobile computing device; and

generate a warning in the event that the accessory did not pass the compatibility test with any mobile computing device model belonging to the same device class as the target mobile computing device and the compatibility test was not waived with respect to at least one mobile computing device model belonging to the same device class as the target mobile computing device.

13. The mobile computing device of claim 12 further comprising:

a display screen,

wherein the processor is further configured such that generating the alert includes displaying an alert message on the display screen.

14. The mobile computing device of claim 12 wherein the plurality of mobile computing device models include at least one smart phone model and at least one tablet computer model.

15. The mobile computing device of claim 12 further comprising:
