Using SDK 3.7.0 does the module support OTA2 and the snip example provided in the sdk?

Please refer to the recent Cypress blog (and files) provided on topic of executing OTA2 Updates using WICED SDK-3.7.0

so from an Avnet perspective OTA2 is known to work with your module if I follow this process? Enough serial flash storage to hold 3 application images, and other resources, etc?

From the Broadcom WICED documentation the AVN module appears to need roughly 3 time the flash and 3 times the ram currently available in the module. Are there any plans to supply a version of this module with enough resources to support OTA2? or will I need to use a Broadcom  BCM94390x module instead?

Feedback from Cypress is that OTA works flawlessly with simple apps like snip.scan. Issues however have been reported when attempting OTA with larger applications. 

 

Cypress Apps Engineering team are reviewing this now and we hope to have an update shortly. FYI recent commentary on this topic at: https://community.cypress.com/message/29426
