How to integrate a Bluetooth module into a Device - Nine Steps for a Successful Project

1. Architecture of my device - how Bluetooth is run

The first matter to consider when starting the design process of a Bluetooth module into a system is to define how Bluetooth wireless technology will be implemented. Basically you have two options:

a) Run the Bluetooth stack 100% in the module or
b) Run the Bluetooth upper layer stack in your host-processor (Host Command Interface, HCI).
 
Once you have set this, you can choose the most suitable product from Bluegiga; WT11, WT12 and WT32 Bluetooth modules can host the stack 100%, but also support HCI Split. Bluegiga's WT21 Bluetooth module supports only HCI mode and offers a cost optimized solution.

2. How my device is used - select the Bluetooth profiles

You need to consider how your device will be used. In practice this means that you need to set and define the Bluetooth profile you will utilize. If your application sample needs to have a wireless serial connection to another device, then you are using Serial Port Profile (SPP). This profile definition is very important and will set the Bluetooth features of your device. This feature will be marketed and mentioned in your product literatures in the future. Bluegiga recommends you to contact us for free support and discuss with our experts the most suitable and efficient profile for your needs.

3. Where to place the Bluetooth module in my device  - put it on the right "corner"

The location of the Bluetooth module in your device needs careful consideration. Bluetooth is radio technology and possible interferences and performance is due to the environment and the location of the module in your device's printed circuit board. In general, the Bluetooth module should be placed in your device so that there aren't any other components close by the Bluetooth module's antenna and the module is not located under your device's other electronics. Bluegiga offers design reviews where our experts validate your design. This service will make sure your product performance will be the most optimal.
 

4. When executing the actual design - check the reference designs

Once you are starting the actual implementation (schematics and PCB), it is good to check and follow Bluegiga's reference designs, datasheets and software manuals. You can download these example designs from Bluegiga's online support: techforum.bluegiga.com
