For the purpose of demo, I connect a cyw920706wcdeval board to my PC and download the below app onto it.
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.
I think this path is use for windows host
is any sample or sop to connect with a linux base host?
The reset process is carried out physically by pressing the "reset" button on my EVK, not via issuing a command.
thus question is for, may I use this J18 uart to sent hci reset command to check connection?
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.
