Hello,

I am looking for information on how to program a new module in-system at our factory. Since SWD is not accessible, where can i find information about the proper interface to use? (would like to confirm our assumption that the ROM code allows programming over the UART TX/RX pins on the CYBT-483062-02 module.)

Thanks!

Hi Zach,

Yes your assumption is correct. CYW20721 chip uses HCI UART for programming. 

I would suggest you to have a look at the CYW208xx Features & Peripherals guide (section 5.11.2 and section 7)- https://www.cypress.com/file/468621/download

Though the document is for CYW208xx chips, programming procedure is same for both the chips.
