Which bluetooth (preferable 4.0) module can I use to attach and transfer digital data collected by a circuit ?

I'm looking to transfer the data from a component like simple digital calculator over bluetooth. I'm looking for advise on a bluetooth module esp 4.0 if available to attach to this ciruit and transfer data.

Sounds like the application that you are building could be run inside a Bluetooth low energy module. Please see following two pages which contain comparison between different module vendors that allow application hosting on their Bluetooth 4.0 modules.
