    CYW920719Q40EVB-01 vendor-specific commands




      I'm trying to send vendor-specific commands to CYW920719Q40EVB-01.


      It's an example, which i'm trying to send (Tx_Test):


      cmd 0x3f 0x0051 0x00 0x01 0x02 0x03 0x04 0x05 0x01 0x00 0x03 0x01 0x00 0x02 0x00 0x00 0x00 0x00

      1. 0x3f Vendor specific
      2. 0x0051 Command (Tx_Test)
      3. 0x00 0x01 0x02 0x03 0x04 0x05 Local BD address
      4. 0x01 Hopping mode(single freq)
      5. 0x00 2402 MHz
      6. 0x03 Modulation_type (0xAA pat)
      7. 0x01 Logical_channel (ACL basic)
      8. 0x00 Packet_Type (NULL)
      9. 0x02 0x00 Packet_Length
      10. 0x00 Tx_Power_Level (0dBm)
      11. 0x00 Transmit_Power_dBm
      12. 0x00 Transmit_Power_Table_idx


      I've used CyBluetool for testing and it worked correct.

      Now i want to create my own firmware and send vendor-specific command using wiced_bt_dev_vendor_specific_command() function from SDK.


      It's a function prototype from SDK:


      * Function         wiced_bt_dev_vendor_specific_command


      *                  Send a vendor specific HCI command to the controller.


      * @param[in]       opcode                : Opcode of vendor specific command

      * @param[in]       param_len         : Length of parameter buffer

      * @param[in]       p_param_buf      : Parameters

      * @param[in]       p_cback               : Callback for command complete


      * @return


      *                  WICED_BT_SUCCESS    : Command sent. Does not expect command complete event. (command complete callback param is NULL)

      *                  WICED_BT_PENDING    : Command sent. Waiting for command complete event.

      *                  WICED_BT_BUSY       : Command not sent. Waiting for command complete event for prior command.



      wiced_result_t wiced_bt_dev_vendor_specific_command (uint16_t opcode, uint8_t param_len, uint8_t *p_param_buf,

                                      wiced_bt_dev_vendor_specific_command_complete_cback_t *p_cback);



      Could you please clarify me which bytes of my command i  should use as param_len and p_param_buf ?


      Or do you have any ideas how can i send vendor-specific commands another way?
