A method for testing Bluetooth® Classic wireless devices includes identifying a Bluetooth® wireless device under test (DUT) by a test device. The method further includes signaling, by the test device and with the Bluetooth® wireless DUT over a Bluetooth® signaling interface, to identify at least one service provided by the Bluetooth® wireless DUT. The method further includes generating commands associated with the at least one service by the test device and based on the at least one service. The method further includes transmitting test packets including the commands to the Bluetooth® wireless DUT by the test device. The method further includes receiving, by the test device, packets including responses to a least some of the commands. The method further includes determining a performance metric of the Bluetooth® wireless DUT by the test device and based on the test packets and the packets including the responses.

Methods and systems for testing Bluetooth® classic wireless devices

A method for testing a DUT, operating in signaling mode, includes receiving sets of advertisements from the DUT over advertising channels; sending queries over one of the advertising channels in each set of advertisements in response to the advertisements; receiving acknowledgements over the one of the advertising channels in response to at least some of the scan requests, respectively; identifying respective advertising channels on which the queries are sent and the acknowledgements are received for each set of advertisements; calculating PER for each of the advertising channels using a ratio of the received and sent acknowledgements and queries; determining RF power of each of the advertising channels based on RF bursts associated with the advertisements and/or acknowledgements; temporally associating the PER and RF power based on timestamping; and determining quality of an RF radio in the DUT based on the associated PER and RF power.

System and method for performing over-the-air testing on devices under test

A method is provided for performing over-the-air (OTA) testing of a device under test (DUT). The method includes establishing an OTA connection with the DUT, while the DUT is in signaling mode, the OTA connection including advertising channels and data channels; sending universally unique identifier (UUID) requests at different transmit powers to the DUT over the data channels of the OTA connection; receiving UUID responses from the DUT over the data channels of the OTA connection in response to at least some of the UIDD requests; and determining a packet error rate (PER) for the received UUID responses from the DUT based on a ratio of a number of received responses and a number of sent connect requests. The determined PER indicates sensitivity of a receiver in the DUT.
