Implementing Bluetooth Wireless Technology in End Products
Over the past few years, Bluetooth technology has been greeted with great enthusiasm from a variety of companies who are keen to implement the technology into their end products. On the whole, Bluetooth is meant to be simple and easy to implement, have low power consumption and be relatively inexpensive. Currently in the market, we are starting to see Bluetooth products (for example, headsets for mobile phone applications, Bluetooth enabled mobile phones and PDAs) from major names such as Ericsson, Sony, Toshiba and Motorola, emerging rapidly to capture market attention. It is estimated that by the year 2005, Bluetooth wireless technology will be a built-in feature available for more than 600 million products worldwide.

It could be argued that there are three main ways to implement Bluetooth wireless technology into an end product. The first is by using a Bluetooth module. This is the easiest method to implement Bluetooth functionality into an end product. It offers the fastest time-to-market solution. However, this is also a very expensive and inflexible method.

The second method is to use a pre-qualified Bluetooth chip set. These are readily available in the market for integration into the system level of the product and major names that offer chip sets include CSR, Zeevo, Philips and Infineon Technologies. The third method is to use a Bluetooth enabled Application Specific Integrated Circuit (ASIC).

Companies can achieve Bluetooth technical capability through in-house development or the licensing of Bluetooth Silicon Intellectual Property (IP). Currently, Bluetooth solutions can be licensed as Intellectual Property (IP) from NewLogic, Ericsson, and ParthusCeva.

Bluetooth is a short range wireless technology mainly used in consumer devices like phone, carkit, headsets, wearable etc. It is for voice and data transfer.
I assume we have a board having a micro controller and we want to implement the Bluetooth connectivity on top of it. so to to this following steps are needed.
1. Chose a BT module (SOC) and attach it in the board.(this is your lower part of BT stack)
2. It will have different pins mainly for Clock, Data transfer, Voice transfer, data control, enable/disable.
3. Connect these pins with the Micro controller in order to have the access for it in MAP software.
4. connect a transport protocol with the data transfer pin (UART/USB).
5. implement minimum upper part of stack( HCI, GAP, SDP).
6. Initialise the BT chip using HCI commands(reset, event mask, host supported feature etc.).
7. Your BT chip is ready to send and receive the commands and talk to external world.
Note: These are high level steps some more details driver and other connection and SW would also be require in order to make this workable and usable solution.
