Abstract

A method for testing a wireless transceiver embedded within a wireless data communication system that also includes a host processor with minimal interaction between the wireless transceiver and the host processor during such testing. The wireless signal interface between the wireless data communication system and external test equipment is used to convey test initiation or data signals from the external test equipment to the wireless data communication system, and responsive data or acknowledgement signals from the wireless data communication system to the external test equipment.

Claims

1. A method for testing data signal transmissions of a wireless transceiver embedded within a wireless data communication system that also includes a host processor with minimal interaction between said wireless transceiver and said host processor during said testing, comprising:

transferring test firmware via said host processor to said wireless transceiver;

setting said wireless transceiver in a test operation mode;

transmitting, with said wireless transceiver in accordance with said transferred test firmware and substantially independently of said host processor, a respective plurality of test data packets in response to reception, by said wireless transceiver, of a corresponding one of a plurality of sequential test initiation signals from a control signal source external to said wireless data communication system, wherein each one of said respective plurality of test data packets is substantially unrelated to said corresponding one of a plurality of sequential test initiation signals; and

determining, with a test system external to said wireless data communication system, validity of each one of said transmitted respective plurality of test data packets irrespective of content of said transmitted respective plurality of test data packets.

2. The method of claim 1, further comprising loading said test firmware into said host processor prior to said transferring said test firmware via said host processor to said wireless transceiver, wherein said test firmware includes a plurality of data corresponding to a test protocol.

3. The method of claim 2, wherein said test firmware further includes another plurality of data corresponding to a test sequence.

4. The method of claim 1, wherein said setting said wireless transceiver in a test operation mode comprises setting said wireless transceiver in a test operation mode responsive to said test firmware transfer.

5. The method of claim 1, wherein said setting said wireless transceiver in a test operation mode comprises setting said wireless transceiver in a test operation mode responsive to reception of a test mode control signal received from said host processor.

6. The method of claim 1, wherein said setting said wireless transceiver in a test operation mode comprises awaiting reception, by said wireless transceiver, of at least a first one of said plurality of sequential test initiation signals from said control signal source external to said wireless data communication system.

7. The method of claim 1, wherein said setting said wireless transceiver in a test operation mode comprises transmitting, with said wireless transceiver, a ready signal indicative of said wireless transceiver being in said test operation mode.

8. The method of claim 1, wherein said transmitting, with said wireless transceiver in accordance with said transferred test firmware, a respective plurality of test data packets in response to reception, by said wireless transceiver, of a corresponding one of a plurality of sequential test initiation signals from a control signal source external to said wireless data communication system comprises transmitting, with said wireless transceiver, a respective plurality of test data packets in response to reception, by said wireless transceiver, of a GOTO-NEXT command signal.

9. The method of claim 1, wherein said transmitting, with said wireless transceiver in accordance with said transferred test firmware, a respective plurality of test data packets in response to reception, by said wireless transceiver, of a corresponding one of a plurality of sequential test initiation signals from a control signal source external to said wireless data communication system comprises transmitting, with said wireless transceiver, an acknowledgement signal.

10. The method of claim 1, wherein said transmitting, with said wireless transceiver in accordance with said transferred test firmware, a respective plurality of test data packets in response to reception, by said wireless transceiver, of a corresponding one of a plurality of sequential test initiation signals from a control signal source external to said wireless data communication system comprises transmitting, with said wireless transceiver, said respective plurality of test data packets in conformance with a predetermined test sequence.

11. A method for testing data signal reception of a wireless transceiver embedded within a wireless data communication system that also includes a host processor with minimal interaction between said wireless transceiver and said host processor during said testing, comprising:

transferring test firmware via said host processor to said wireless transceiver;

setting said wireless transceiver in a test operation mode;

receiving, with said wireless transceiver, a plurality of test data packets from a data signal source external to said wireless data communication system; and

transmitting, with said wireless transceiver in accordance with said transferred test firmware, at least one acknowledgement signal in response to reception of each one of said plurality of test data packets that is recognized by said wireless transceiver as one of a plurality of predetermined data packet types.

12. The method of claim 11, further comprising loading said test firmware into said host processor prior to said transferring said test firmware via said host processor to said wireless transceiver, wherein said test firmware includes a plurality of data corresponding to a test protocol.

13. The method of claim 12, wherein said test firmware further includes another plurality of data corresponding to a test sequence.

14. The method of claim 11, further comprising receiving, with said wireless transceiver, at least one test initiation signal prior to said receiving, with said wireless transceiver, a plurality of test data packets from a data signal source external to said wireless data communication system.

15. The method of claim 11, wherein said setting said wireless transceiver in a test operation mode comprises setting said wireless transceiver in a test operation mode responsive to said test firmware transfer.

16. The method of claim 11, wherein said setting said wireless transceiver in a test operation mode comprises setting said wireless transceiver in a test operation mode responsive to reception of a test mode control signal received from said host processor.

17. The method of claim 11, wherein said setting said wireless transceiver in a test operation mode comprises awaiting reception, by said wireless transceiver, of one or more predetermined test initiation signals from a control signal source external to said wireless data communication system.

18. The method of claim 11, wherein said setting said wireless transceiver in a test operation mode comprises transmitting, with said wireless transceiver, a ready signal indicative of said wireless transceiver being in said test operation mode.
