    Hi, Nagalla
    jung tae park is our team member.

    we use pmPairableMode_EnableSecureSimplePairing options when pairing the device.
    My reference product does not display a popup confirmation window when you first pair the device.

    So, you are pairing from a smart phone to a device having CC2564B right? Did, you try setting the IO capability to, "icNoInputNoOutput". this would result in "just works".

    Thanks

    Hi, Nagalla 

     I pairing from a  my cc2564b bluetooth device to smartphone using HIDConnectRemoteHost functions in HID profiles.

    I'v used the IO capability as below,but not solved the problems.

    #define DEFAULT_IO_CAPABILITY (icNoInputNoOutput) /* Denotes the */

    Best regards,

    JH.

    That should work.. I tried with the HID demo on MSP432+CC2564B and it worked just fine, it paired with iPhone without asking for PIN code. Make, sure you are not changing the 'IOCapability' later in the program to some thing else.. Which, host processor are you using?

    #define DEFAULT_IO_CAPABILITY (icNoInputNoOutput) /* Denotes the */
    /* default I/O */
    /* Capability that is*/
    /* used with Secure */
    /* Simple Pairing. */

    #define DEFAULT_MITM_PROTECTION (TRUE) /* Denotes the */
    /* default value used*/
    /* for Man in the */
    /* Middle (MITM) */
    /* protection used */
    /* with Secure Simple*/
    /* Pairing. */

    Thanks

    Hi

    I was on vacation and the answer was late.

    The project uses STM32F4 + CC2564B.

    I tried to do it and it looks the same.

    Will, it be possible to try with the HID demo sample? If, you still have issues with the demo, we need to somehow take the HCI/UARt logs. Do, you have access to the BT UART/HCI Tx/Rx pins?

    Thanks

    Is the issue resolved now? I am closing the thread for now.. If, you still have issue please open a new thread with HCI/UART logs..

    Please, review section 4.1.2 of the hCI logging Application note : www.ti.com/.../swpa234.pdf

    Thanks

    Hi Nagalla,
    The answer was late.
    Still, I can not solve this problem.
    Even if I use all the options below, a popup window will appear when I connect the Bluetooth.
    #define DEFAULT_IO_CAPABILITY (icNoInputNoOutput) / * Denotes the * /
    #define DEFAULT_MITM_PROTECTION (TRUE) / * Denotes the * /

    thank you.

    Hi Nagalla,

    Ask again.

    1. Connect device and smartphone Bluetooth for the first time.

    2. The confirmation pop-up window pops up at first.

    3. Save Bluetooth LinkKeyInfo information to MCU.

    4. When you reconnect your smartphone and Bluetooth later,
    Load stored LinkKeyInfo.

    5. Do not pop-up windows at this time.

    Thank you.

    forest.

    Please, take firmware or BT sniff logs. We, are not able to reproduce the issue with MSP432 and CC2564B..

    Thanks

    HI

    BT logo will be sent to you soon.
    Another question.
    STM32 MCU+ cc2564b,
    To reduce the operating current, a dynamic clock change function is implemented.
    I want BT to work in the following scenarios:

    1. Initialization and operation of CC2564b when booting MCU clock to 56MHZ.

    2. When not using CC2564b, switch MCU clock to 16MHz.

    3. Change the mcu clock to 56mz to use the CC2564b again,
         This time reconfigure MCU uart clock and cc2564 does not work.

    4. It seems that the communication is not possible with the CC2564 hci uart.
    Reconfigure MCU uart and reconfigure CC2564 hci uart to operate normally
    How do I do that?

    When changing the clock, reconfigure HCI uart again using HCITR_COMReconfigure function in HCItrans.c does not work.
    please check.

    hI~

    The BT logo you requested.
    Send with BT logo.
    scenario
    1. Set on
    2. Connect device BT on your smartphone.
    3. Set power off (save link key information at this time)
    4. Set power on (link key information recovery at this time)
    5. Reconnect with your smartphone with the HIDConnectRemoteHost function.
    6. At this time, a popup window appears.

    We want to make the popup window disappear.
    please check.cc2564_dump.zip
    Have a good day
