Uanble to connect to Evaluation Board CYW20735 #12

Closed wuruoyu closed 4 years ago

Hi,

I have an issue connecting to the Evaluation board CYW20735. The jumpers on the board are set as default and the demo application from WICED can be successfully downloaded to board. But it seems that Internalblue does not identify it as Cypress chipset. I print out the vendor ID, and it is 29 (0x1D). The screenshot is attached below: image

Do I do something wrong or forget to set something? I appreciate your help in advance!

Respectfully, Ruoyu

Hi Ruoyu :)

29 is Qualcomm (see https://www.bluetooth.com/specifications/assigned-numbers/company-identifiers/), so you're likely using your internal Bluetooth chip instead. The evaluation board's MAC address always starts with 20:73:... and so on, similar to its version.

The evaluation board itself will not work out of the box, you need to follow the steps listed here. Often this will only work after a few tries, but what always works for me is to use the ClientControl binary in WICED Studio and open and close the serial port, and then attach with btattach.

Hi, would you teach me how to use CYW20735 with Internalblue? I am fresh man in this field. I don't understand if there is no ADB in CYW, is it really possible to communicate with Internalblue ? Thank you.
