You said that "I hope you can direct me to an application engineer that can support this project." but nobody given answer. Okay I hope application engineer who come and given right answer.

Hi Morten, this really all boils down to available bandwidth, transmission duty-cycle and physical proximity. If all the devices plan to talk to one 'hub' then the potential will be drastically reduced.

There isn't a specific limitation specified for maximum number of connectable devices in one area in the Bluetooth specification. However this requires looking at the size of each packet payload + all overhead and factor into your calculations how many of those transmission could happen in a set period.

So for instance every 10 secs would give your potentially 10 million bits to play with at BLE's rate of 1Mbs, you can divide your packet into that. I would stress though that this is at the highest level, there will be turnaround times and other timing considerations that will pull this theoretical figure down a long way. Also phone manufacturers can of course implement their own limitations if they don't want the phone to be used in such a way.
