Thanks for your help .

Yes - that's the idea.

Are you familiar with the concept of a Ring - aka "Circular" - Buffer?

So i like declare a buffer N times the size of my data frame so that it can store a data frame upto N times and then send it over BLE?

Yes, but you only have a finite amount of memory anyhow.

You have to fix the heap size at build time anyhow.

So, whatever way you do it, you are going to have define that maximum amount of data you can ever have buffered.

Dynamic allocation brings a number of issues and overheads ...

A ring buffer has a fixed size no?

How am I suppose to use that in my application?

Why do you want a dynamic buffer for that?

A Ring Buffer would do the job ...

That's a C++ thing ...
