What is the "Stack"?
The word "stack" is frequenly. What is the precise definition of the Bluetooth "stack" in the Cypress world? Is this the binary (closed source) API functions? Or something else?
I am wondering since I have implemented Upgradable Stack OTA Bootloader to be able to update my application in the field. Now I've did a small modification: I've changed the UUID of one of my Characteristics. I initially thought that "Upgradable Stack" just meant that I would be able to update the Cypress Bluetooth library (to for example fix bugs in the API functions). But maybe changing the GATT server of my main application will also qualify as a stack update?
