Pin 5 to 8 of J18 are dedicated pins of the HCI UART for 20706. You may issue HCI commands via here when the IC is rebooted in HCI mode. Do also ensure that all the pins of J26 are all closed on the eval board.

For the purpose of demo, I connect a cyw920706wcdeval board to my PC and download the below app onto it.

snip.hal.puart-CYW920706WCDEVAL download

In my device hardware manager, com5 is hci port and com6 is puart.

I use tera term to connect to com6 and do a reset of the eval board. Now follow the on-screen instruction and whatever

you type on the keyboard will be reflected on it. This app will give you an idea on how to use the puart driver interface to

send and receive.

The reset process is carried out physically by pressing the "reset" button on my EVK, not via issuing a command.

I assumed that you are using the cyw920706wcdeval board, then you may refer to the kit guide within the Doc folder of the SDK on how to recover this board. This will force the chip to reboot in HCI mode.

BoonT_56​ , thank you and yes I am using cyw920706wcdeval

after reset using method in section Appendix D, I think this would be in HCI mode,

thus, I through J18 uart tx/rx to set try reset command through ubuntu like

"echo -e -n \\x01\\x03\\x0C\\x00 > /dev/ttySX" but not worked, could you comment on how to set "HCI reset" by through this , thank you
