CYW20719 in HCI mode

[JaLe_4525111]

Hi

     I am using the CYW920719Q40EVB-01 evaluation kit

     I already finish the following items.

     1. Create a new project in WICED with just one file which is empty:

     #include "sparcommon.h"

     APPLICATION_START() {}

     2. Download this project from WICED onto your board.

     I could sending commands with CyBluetool, and received the correct event.

     11/28/19 18:09:19.115  com8 <c Reset

       HCI Command Complete Event

     com8@115200

     [0E 04 ]: 01 03 0C 00

     event = 0x0E (14,"Command Complete")

     Num_HCI_Command_Packets = 0x1 (1)

     Command_Opcode = 0xC03 (3075, "Reset")

     Status = 0x0 (0, "Success", "Success")

     But if i use other UART console AP, sending the command "01 03 0c 00"

     Why i can't receive any feedback by UART console AP?

     Have any other setting or initial command to do?

Hi JaLe_4525111​

UART console AP -> Can you please provide information about your host and how you are actually trying to communicate with the device?.

Can you try following workarounds:

1- Do hard reset and then connect the HCI port. After that send HCI reset.

2. Do Recovery and try sending the HCI command.

Recover steps: Reset the board while you are pressing the Recover button and then release the recover button.

Thanks,
