Characteristics Per Service

Hi,

I am trying to understand the max number of characterstics per service; In the forms some say it's limited based on the memory allocated for the GATT table internally and some say it's not dependent on the memory. It's not clear for me.

Right now I am having up to 24 characteristics and If I add another new characterstic; It doesn't show in the advertisnment data. What's the maximum number of characterstics per service and what's it dependent on?

Thank you,
