Hello!
I have some troubles with UART. I'm trying to send message using wiced transport, but I don't recive expected message from another side.
I used different modes of operation for UART:
WICED_TRANSPORT_UART_HCI_MODE,
WICED_TRANSPORT_UART_RAW_MODE,
Code:
uint8_t data[] = "\x01\x00\x21\x02\x11\x01\xBD\x67";
wiced_result_t res = wiced_transport_send_data( HCI_CONTROL_COMMAND_UNBOND, data, sizeof(data));
if (res != WICED_SUCCESS)
{
WICED_BT_TRACE ( "Cannot send maja message \n");
}
Expected result: 01 00 21 02 11 01 BD 67 00
Current result: 19 0A 00 09 00 01 00 21 02 11 01 BD 67 00
How to avoid the appearance of a header '19 0A 00 09 00' in a message received through UART.
Thank you.

Hi AlGo_4347736,
As per my understanding, 19 stands for HCI WICED Packet. 0A is the operating code for Unbond command as you are using code HCI_CONTROL_COMMAND_UNBOND. 00 is the group code suggesting group HCI_CONTROL_GROUP_DEVICE. Next bytes are the packet length.
Please check WICED HCI UART Control Protocol document Page 16 for more details (/20719-B1_Bluetooth/doc/WICED-HCI-Control-Protocol.pdf).

Hi SheetalJ_96!
What it is and how it is formed I understand.
The question is, how do I disable sending the header when sending data to UART?
What if I just want to send my bytes buffer without any additional automatically generated bytes?
