We have a development project to design a Pulse Oximeter capable of BLE and BR performance. Cypress module CYBT-423028-02 looks to be a good fit.

Question 1: Is the stack running on the CYBT-423028-02 or do I need to run the stack on a separate microcontroller?

Question 2: Our application requires a number of security features including secure boot which ensures that only authenticated software can run on the module. Does the CYBT-423028-02 support this?

The stack is hosted on the module.

The internal CYW20719 essentially has an internal 96-MHz Cortex®-M4 with 512KB SRAM, 1MB Flash, 2 MB ROM for the stack and drivers.

This means that both the Flash and RAM are available for the application.
