What is the procedure to enable direct test mode for TI CC26 for Bluetooth SIG Qualification? Do we need to pass any commands using BTool?

We are doing Bluetooth SIG RF PHY Qualification testing of a device based on TI CC26. The tester is not able to access the device under test radio signals. We are doubting whether direct test mode is enabled. Is there command to be sent through BTool?

Hello,

Please refer to the Certification section / column of the TI BLE Wiki. Specifically, see the "How to Certify" and PTM articles.

We could perform transmission test and receiver test using BTool application. But when we do testing with BITE tester, tester is not able to connect with TI DUT. What is the HCI interface to be used for TI? is it HCI or 2 wire?

The transmit and receive test is successful using BTool. But for Bluetooth certification, test house will use BITE tester to connect to DUT and make connections and run test scripts as per test spec. tester is not able to connect with DUT. Is the HCI communication routed via HCI or 2 wire? If 2wire, what is the corresponding setting for CC26?

The BLE-Stack uses HCI UART for DTM test commands. Refer to app note SWRA530 - Configuring the CC2640 for Bluetooth® Direct Test Mode: www.ti.com/.../swra530.pdf

We have used HCI option for connecting, instead of 2 wire and tester is able to connect with module. Thanks a lot for the suggestions.
