The Conducted Susceptibility which belongs to EN30149.

During the test will put the nosie source from the AC adaptor when the about to 9M~10MHz frquency that the BLE signal will disconnect.

  • Hi Kent,

    Thank you for reaching out.

    • Can you specify the SDK version used?
    • Have you run the failing test using TI evaluation modules? What are the results?
    • Can you confirm all the other tests are passing?  
    • Do you know how the Bluetooth transmission is made? It should be possible to enable Bluetooth transmission using Bluetooth test packets, using Bluetooth advertising or forming a Bluetooth connection.

    Best regards,
