Bluetopia®4.0 — Bluetooth Protocol Stack
Bluetooth Classic & Bluetooth low energy Technology


Bluetopia®4.0 is built upon the solid foundation of the Bluetopia® protocol stack that is currently being used in millions of consumer and industrial devices and that was first qualified in 2000.  Developed in ANSI-C, Bluetopia® 4.0 is easily portable to all IC platforms and operating systems and is scalable in memory and processing throughput based on the exact needs of the application 

The Bluetopia® 4.0 SDK is comprised of Single Mode and Dual Mode offering.


  • Optimized for embedded applications and available on most operating systems and processors
  • Highly reliable and shipped in millions of devices
  • Fully Qualified
  • Simple interface with excellent sample applications to speed development
  • Supports all Bluetooth profiles

About Bluetooth LE
Bluetooth Low Energy (BLE) extends the capability of Bluetooth to enable developers to design a wide range of new light duty devices that support small data throughput and operate a long time on a coin-sized battery.

Bluetooth Low Energy or BLE is a perfect candidate for use in the healthcare, fitness, security and home entertainment industries and opens up an array of new devices and applications.  BLE paves the way for a multitude of new body-worn communication devices and sensors that could be used to collect heart rate, temperature, glucose readings and numerous other medical and fitness related measurements.  In addition, BLE is expanding the reach and capabilities of a host of machine to machine products. All the tools to support these new applications are now available.

Most of the difference between regular Bluetooth BR/EDR and BluetoothLE resides in the stack. The RF section is mostly reused. The Bluetooth 4.0 specification imposes 2 types of devices: 

Dual mode which is able to support Bluetooth LE in addition to the regular Bluetooth BR/EDR


A single mode device, which supports only Bluetooth LE protocol.

This separation allows for asymmetrical network nodes and helps to take advantage of the simplicity of a single mode stack for sensor-like devices in combination with the versatility of a dual mode stack for more complex multifunction devices such as mobile phones
