Need information about Bluetooth chip

Hello

I have some basic questions concerning bluetooth chips and please bare with me, I'm new to bluetooth + my mold told me there are no bad questions, just bad answers!

1. Are there any bluetooth chips that can work without a host, and with that I mean that you don't have to plug the bluetooth chip into a computer. If so, how long does it last till you need to recharge/change the battery of that bluetooth chip?
2. Can anyone recommend a shop that sells those kind of bluetooth chips, or give me the names of those models(low energy with short distance models, 0-10m).
3. When you talk about a bluetooth chip, is an antenna which receives the signals included?

4. Scenario/final question, say I have this bluetooth chip called "A" that isn't connected to anything and I have a macbook which has a bluetooth chip "B" of its own. Can I just use my macbooks bluetooth "B" to check if bluetooth chip "A" is there so to speak, and if so, can I connect to it?

That's all, thanks in advance for taking your time to read and respond.

You just need to connect this to a UART port of a uCU and you got a bluetooth.

What is a uCU?
Have I understood this correct.

First you have a bluetooth chip(with a receiver and a sender, the information the chip receives is via its antenna). Now you connect the bluetooth chip to a UART port so that the signal you are receiving is translated or something? If so, -how big is this UART port
-does it require any sort of battery
-can it be portable, and if so, how small?

I know I'm asking a lot of questions and I really appreciate you guys(n girls) for taking your time.

uCU = Micro-controller Unit
Go to Wikipedia to find out if you don't know what is Micro-controller. It will be wastage of time to start explaining that here.

UART port for YOUR purpose is simply the serial port on a micro-controller/microprocessor.

I see, I found this device on a site. Will this bluetooth chip do the work?

Can anyone recommend any good uCU with a UART port that is compatible with any of these modules.

Also, where does the battery go?

most of the micro controller comes with uart you can use any one from atmel, avr, arm, atmega,pic etc till now i have only used atmel chips 89c52 is easy to learn and interface with ur bluetooh module via uart.

bluetooth module doesnot comes with battery or socket for it.. so you have to give them power via their power pins..

as u might have seem bluetooh devices in ur pc get power from usb..

u can use a battery and same can give power to ur micro controller and blue tooth module...

u can use 2 coin cells which will give u 6.6v and using ldo low drop out regulator u get 5v to run ur hardware

Thanks for clarifying a lot. Are there by any means any smaller micro controllers, like maxium 5x5 cm available? I found this site electrokit | elektronikbyggsatser | elektronikkomponenter | lysdioder | radio | LED | audio
I'm just wondering is there anything specific I should be looking for when buying a microcontroller other than uart compatible?

For the bluetooth, just the uart.But take, most of bluetooth modules that i know run at 3.3V and not 5V. But why exactly you need bluetooth?

Is this matter required for your project work or is it personnel interest?

I have gotten a lot of information from this forum, I just want to say thank you everyone for taking your time handing out information pro bono!
To your question Jerin, this is more of a personal interest where I am first looking into building a basic and preferably small bluetooth device(that at the beginning will only be visible to the master, no data transfer are required) that is powerefficient so you don't have to recharge it for like 10+ days or something and when you load it, it should be through your computer(usb).

edit:
I've been reading upon these SoC's, are they the complete solution so to speak, they include both the BT-module and the uC in one as well as a battery holder? Are there any available on the market? All I've come across is the csr company, but they don't seem to sell to private persons.

IF you get to it do post it in edaboard. It will be helpful to all.
Good luck!!!!!!!

post the link of SOC we will study the datasheet and then let u know how to use that...

Hmmm.i dont know about bluetooth, but Texas Instruments and Atmel got a SoC with a uCU and ZigBee tranceiver.
