How to enter download mode

[YaTr_3516311]

Hi,

I want to test HCI commands. So I use CYBT-343026-01 EVAL board. Let HCI UART's CTS OFF then RESET. Then I enter "01 03 0C 00" command from PUART. No command response.

1.Is my operation right?

2. Is it OK to use ezserial_343026-CYBT_343026_EVAL-rom-ram-Wiced-release.hex?

Hi YaTr_3516311​,

You have to send HCI commands via HCI UART itself after recovery. I would recommend you to go through Programming an EZ-BT WICED Module – KBA223428 .

This will help you to start with the programming.

Hi,

Sorry that I don't explain clearly. I don't want to download FW.  I want to test HCI commands.

And I see "For the case of UART, the device behavior depends on the state of CTS when RST_N is de-asserted. If

CTS is low at this time, then the device enters the autobaud state (download mode)."  in "HCI UART Control Protocol",

so I do the above steps. But no respnose for command.I also tried to send command from HCI uart, still no response.
