I would like to ask, when I set the broadcast frame to carry CTE on the basis of Bluetooth protocol, will the master automatically trigger IQ sampling? In other words, what are the conditions for the master to trigger IQ sampling?

    Hi,

    The radio triggers IQ sampling if the following elements are verified:

    • the radio is enabled to perform IQ sampling by the Application - done by the RTLS framework
    • the incoming PDU is valid and contains a CTEInfo field

    Alternatively, IQ data sampling is perform when the radio is set in test mode and receive a test packet with an appended CTE. Please refer to HCI_LE_EnhancedCteRxTestCmd  and HCI_LE_EnhancedCteTxTestCmd (for CTE TX). These commands are Bluetooth Test Commands. They are also documented in the Bluetooth Core Specifications. Please note these cannot be used unless the device is in test mode. If needed, these commands can be enabled on the host_test example. Please search the forum for more details.

    Best regards,
