Hi ,

I want to add OTA to watch demo in 20719(now in 20706) which communicate with host ST MCU through UART.

I have seen ota_firmware_upgrade demo and WICED-Firmware-Upgrade-Library.pdf,

but I have a question:

If I port those code to watch demo,should host ST do something with UART?

Thanks ,

Leo

No, you don't have to do anything with host side or UART.

And preferably, don't do any transaction from host to 20706 during the OTA upgrade (from OTA enabled till OTA ends)

Thanks,

Anjana
