Arduino Bluetooth Push Notification Project

currently I have been trying to build a hub that is powered by an arduino. I made it controllable by IR and it controls IR slaves around the room such as mood lights and auto-feeding a fish tank. But I would like it if would include an bluetooth module that would notify you when you receive a call or SMS message. I wanted to ask which module would be best for this project and how the code would work (if it is not self explanatory). It has a hard state alarm system hooked in too which is pure basic parts, no arduino though t connects to it to sound an alarm. It has a simple piezo beeper attached to pin one and I want it to beep twice for SMS and beep three times for a call and a constant beep when the alarm signal is triggered until the pass is typed into the logic gate system.

If you need more information please just ask.

BTW: I am working on a wrist band that has a few buttons on it that transmits IR signals it's pretty simple but I need a small battery for it. It uses Arduino Pro mini (tested with nano).
