CYW4343W (LAIRD EWB) OTA & OTA2 Examples

[RoMc_863046]

Hello,

I am looking for a functional example of using WICED OTA and OTA2 with the CYW4343W (LAIRD EWB).

The OTA example compiles and runs on the module however, after applying the update, the module does not run the new firmware.  It appears the OTA2 examples, were not written with the CYW4343W in mind.  Any assistance in this would be greatly appreciated.  My target requires OTA2 however, operation and understanding of OTA would be beneficial as well.

Thank you,

-Rocko

@RoMc_863046 Yes your understanding is right. OTA2 isn't compatible with the 4343W due to memory issues. These threads will give you more insight on that https://community.cypress.com/t5/WICED-Studio-Wi-Fi-Combo/Key-differences-between-OTA-and-OTA2-in-WI...

OTA2 does have an advantage of offering firmware update. There was a possible solution given out by the community at https://community.cypress.com/t5/WICED-Studio-Wi-Fi-Combo/Updating-4343W-wifi-firmware-for-our-modul... although we haven't tested this.

OTA should work out of the Box. Did you push the .stripped.elf file generated in the build folder as the update file?

Thanks

@Murali_R 

Thank you for confirming OTA2 is not compatible with 4343W and for confirming that OTA should work.  

For OTA, I did push the .stripped.elf file generated in the build as the update file.  I will try to work though this again and provide feedback.  Thank you.
