CYBT-353027-02 OTA limits - how big is BLE stack and typical size of application code?

[GrCa_1363456]

Does CYBT-353027-02 have sufficient internal memory to support full (App code & Stack) or partial (Application only or Stack Only) OTA?

How large is the bluetooth stack for CYBT-353027-02?

How large is a typical application?

The base device for this part is CYW20707 according to section "WICED-based EZ-BLE and EZ-BT Modules" in the "Modules" tab @ https://www.cypress.com/products/ble-bluetooth    CYW20707 as the base is odd because CYW20707 is NOT widely supported and apparently uses external host and stack per the discussion, "The differences between CYW20704, CYW20706 & CYW20707" @ https://community.cypress.com/message/146477    Is CYBT-353027-02 really supported by CYW20706 which has internal host and stack?

Hi GrCa_1363456 ,

Yes, the onboard flash of 512KB is sufficient for OTA. We have OTA example for CYBT-353027-02 available in MTB. You may refer the same.

Yes CYBT-353027-02 supports the internal host & stack.

- How large is the bluetooth stack for CYBT-353027-02?

  The BT stack is in ROM code.

- How large is a typical application?

   Depending upon the customer application the memory size & utilization varies. In the MTB build logs, you can see the total application size ( RAM ) for the specific generated code.
