CC2564: Bluetooth Stack SPP mode - code size

Part Number: CC2564
Other Parts Discussed in Thread: CC256XM4BTBLESW

Hi everyone,

I'm sorry if this is a recurring question. I've been searching and didn't quite find a definite answer.
I want to use the CC2564B with a Tiva MCU. The idea is to just make a serial port by bluetooth. 

Right now I just want to know what code size could I expect. 
I saw answers saying about 54KB, others about 24KB. The demo seems to have about 107KB in release build. 

Any help would be appreciated :)

    Hi Luis,

    Can you please point me to the source that mentions the 54KB/24KB?

    The SPPDemo in the CC256XM4BTBLESW is about 124KB (including stack, application, driverlib and Tivawere) when built with CCS in TM4C129X NoOS Debug build configurations.

    Looking at the breakdown in the map file, it looks like you can expect 80KB to 100KB for the stack components and MCU files (like driverlib and Tivaware). Having the SPP application on top of the stack will add to this.

    Hope this helps get you a ballpark estimate of what code size to expect.

    Best regards,
    Vihang
