Thank you Zahid Haq for the answer. But as I have mention before, I have already passed the stage of using successfully the demos. To modify the demos, one would need to greatly understand their structure. Simple changes are easy to be done, but to write more complicated projects would be hard to write in such manner.
I couldn't find a guide / instructions of how to modify a demo and make it suitable for any general project.
I have many years of experience in embedded development, but not with Bluetooth development. The demos are great to let you start and play with the board, and see what you can and cannot do with the Bluetooth, but in my opinion they are not sufficient for a developer to move to the next phase and develop products using Bluetooth and this Bluetooth stack.
I also find that the support in this way is very little and very slow. We have taken a decision to use this component based on the demos and its capabilities, but if this cannot mature to a product level in a reasonable time, we will have to look at other options in spite of the effort and money we put into this component.
Thank you,
Guy
