Hi,

I'm looking for the procedure to udpate FW of CYBT-343026 from Host CPU and OTA.

Q1: Is there any good document and sample source code to update FW from Host CPU.

I think HCI UART under programming mode could be used by we are not sure host CPU control side.

Q2: Does CYBT module support OTA FW update?

       If so , is there any sample application and smartphone application?

Thank you.

Hi,

For downloading to CYW20706, you can use UART HCI.

Please go through WICED HCI UART Control Protocol pdf (/20706-A2_Bluetooth/doc/WICED-HCI-Control-Protocol.pdf) available in WICED studio for the downloading process flow.

OTA FW upgrade example project and peer app is available in the WICED studio. Please refer the same.

Anjana

Hi Anjana

Thanks for your prompt update.

Let me check.

BTW, the directory of documents is follows if using WICED 5.1 and 6.1 as follows.

<WICED Install Directory>\Doc

This is for just in case.
