BM64 disable pairing

Hello,
how is it possible to disable pairing with the BM64 device? I only want the BM64 to be in pairing mode for a given time. Otherwise pairing must be disabled so that unknown devices can't connect.
Regards,
Marc

    hi o think that the downloadable .reg files will modify the DWORD value in the registry Tutuapp 9apps Showbox key displaying.

    Every post from this user contains hidden spammy links.
    I reported them two days ago, but things move pretty slowly around here.

    Shocking that you never got any support for this. The functionality you describe can be attained by issuing the correct UART commands as specified in the 'UART_CommandSet_v172_20160317' excel file, which specifies the command set of the module. 
     
    By issuing the 'BTM_Parameter_Setting' command (0x07), with the type field set to 0x00 - 'pairing timeout value setting' (this will not write into eeprom), you can explicitly set the timeout value in units of 30.08s.
     
    The format of the entire UART string will be..
     
    0xAA, 0x00, 0x03, 0x07, 0x00, 0x03, checksum_byte
     
    First and second bytes are standard for every command. Third byte states the number of data bytes in the following command string, which, as can be seen is 3. The command value is then issued (0x07), followed by type field 0x00 (as previously described), the final byte is the timeout in units of 30.08s. 
     
    The checksum is the one's complement (~ operator) of the arithmetic sum of the length byte (3rd byte in string above) through to the last data byte, plus one, described by below..
     
    static uint8_t calculateChecksum(uint8_t* startByte, uint8_t* endByte)
    {
        uint8_t checksum = 0;
        while(startByte <= endByte)
        {
            checksum += *startByte;
            startByte++;
        }
        checksum = ~checksum + 1;
        return checksum;
    }



    Cheers,Chris.

    The UART is be enabled by default, if not, then UART needs to be enabled using the UI tool and programmed into EEPROM. Use the SPKCommandSetTool v160.024.exe file to communicate with the BM62/BM64 over UART.
