What are the key differences between OTA and OTA2 in WICED?

Do either allow partial update - WiFi Stack only / BLE Stack only / User Application only?

Do both provide ability for code verification?

Are all WICED radios supported by one or the other OTA or OTA2?

Hello user_455868498

Please refer the table given in Over The Air update in CYW43907​ for the key differences in OTA and OTA2.

Do either allow partial update - WiFi Stack only / BLE Stack only / User Application only?

>> OTA allows only the application to be updated. OTA2 allows the update of the entire application+ firmware + filesystem. OTA2 does not allow partial update.

Do both provide ability for code verification?

>> I am inferring this as whether the updated image which is OTAed is verfied on the device?

OTA and OTA2 check for a valid image before loading the new image.  

Are all WICED radios supported by one or the other OTA or OTA2?

>> Yes. OTA2 is supported only in CYW943907/54907. Rest of the devices support OTA.

The docs directory in WICED(@WICED-Studio-x.x\43xxx_Wi-Fi\doc\) contains documents on WICED-OTA and WICED-OTA2.
