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.
