I would like to ask how to calculate the current consumption of a device with both Central and Peripheral role?

At the current time you can calculate the current consumption for advertising and peripheral connections, but not central connections.
So if you want find the current consumption for a device with both central and peripheral roles you will have to measure it. For this I recommend buying the Power Profiler Kit. You can read more about it at the product page, and in this blog post.

I have the tools for measuring current on the DK board (a digital storage oscillator with differtial probe), but I want to estimate (or have an idea) of the current consumption before I developed the application. For example, if I set the connection interval to 500ms, can I assume that the Central device can also sleep (System-On) in between the 500ms connection interval? It is because in my application, if I can assume it can sleep (in uA) in between the connection interval, the power consumption of the BLE part will be insignificant.
Yes, the central can sleep(System-On) between the connection interval, using only a few µA.
