The bluetooth ceramic chip module profiles

Every bluetooth ceramic chip module comes with a so-called protocol stack. This is a software package that contains the services for using various Bluetooth profiles. Similar to the drivers on a computer, these profiles determine what kind of data can be transferred between devices and what services are thereby available.

The profiles that a device can master can usually be read from its technical data. In order to make certain functions usable, all devices involved must support the same profiles. Often you can find missing profiles e.g. B. refer to the website of the chip manufacturer or stack provider and add.

The following table lists some commonly used standard profiles. However, since new profiles are constantly being added in order to be able to react flexibly to new bluetooth ceramic chip module requirements, it does not claim to be complete.

What types of devices is bluetooth ceramic chip module used for?

There are numerous possible uses and areas of application for Bluetooth. Therefore, only a few examples are given below.

Bluetooth ceramic chip module for Computers and notebooks:

Generally, many current Windows and Linux operating systems support Bluetooth as standard. A chip built into the hardware enables various peripheral devices such as mice, keyboards, headphones and printers to be connected. In addition, the radio technology is used for security tokens as part of two-factor authentication.

Bluetooth ceramic chip modules for mobile devices:

Bluetooth ceramic chip modules are built into practically all modern cell phones and tablets. Moreover, with their help z. B. Sync files, photos and videos with your home computer.

Bluetooth inside the audio output devices:

Many wireless speakers and headsets have Bluetooth, with which MP3 files can be played directly from the smartphone.

Why Bluetooth is used in hands-free systems?

If the smartphone is connected to the hands-free system in the car radio or in the motorcycle helmet via Bluetooth, incoming calls can be accepted directly. 

In well-equipped motor vehicles, the on-board computer is also compatible with radio technology, so that the contacts and menus on the mobile phone can be navigated via the cockpit display.

Bluetooth for fitness equipment and smart home technology:

Some fitness trackers and smart watches send health data directly to a health app on the smartphone via Bluetooth. Bluetooth ceramic chip module enabled kitchen appliances, alarm systems, electronic keys and digital picture frames also contribute to the global triumph of smart home systems.

Toys and Gaming Consoles have blue tooth:

The toy industry is constantly introducing new dolls and action figures that can communicate and interact with each other via Bluetooth. The game controllers of popular video game consoles such as the Nintendo Switch, PlayStation 4 and Xbox One also work via the wireless standard.

Use of ceramic chip modules for medical technology:

Hearing aids in higher price ranges equippe with hands-free functions thanks to Bluetooth. Similarly, it is also possible to configure advanced arm and leg prostheses, insulin pumps and blood glucose meters by radio.

Need of Bluetooth in industry:

Last but not least, wireless communication technology advances industry itself by networking machines use blue tooth ceramic chip module and production systems and thus making it possible to largely automate production processes.

Which bluetooth ceramic chip module versions are there?

In mid-1999, Bluetooth 1.0a, the first version of the new radio standard with a data transmission rate of 732.2 kbit / s at the time, was released. However, just like its successor 1.0b, it struggled with some initial flaws and security problems. 

Only Bluetooth 1.1 (early 2001) formed a solid foundation for marketable products. Since then, the system has been continuously developed and improved, with particular attention being paid to security, interference resistance and connection speed.

The result is a variety of bluetooth ceramic chip module that builds on each other and differs primarily in their maximum possible data transmission rate, but also in their functionality and their area of ​​application.

Bluetooth 3.0 + HSApril 200924 Mbit / sAdditional high-speed channel (HS) based on WLAN and UWB (ultra broadband)

Use of version 4.1

Version 4.1 now allows small devices to communicate with other devices even without an "intermediary".  Furthermore, a fitness bracelet can control a heart rate monitor directly without having to go via a smartphone.

Characteristics of version 4.2

 Another innovation is the support of IPv6, which means that every bluetooth ceramic chip module enabled IoT device has its own IP address, which its user can use to control it from the Internet. However, the highest technical level has so far been version 4.2.

Similarly, it is characterized by smaller data packets as well as higher speed, longer battery life and more security.
