How Bluetooth Technology Works?


Bluetooth technology is a global standard for open wireless data and voice communication. It is a special short-range wireless technology connection based on low-cost short-range wireless connection, which establishes communication environment for fixed and mobile devices.

Bluetooth enables today's portable mobile devices and computer devices to connect to the Internet without cable and wireless access to the Internet.

It can exchange wireless information among many devices, including mobile phones, PDA, wireless headphones, notebook computers, related peripherals and so on.


Bluetooth Technology


Bluetooth is a low-cost and low-power short-range wireless communication tool. Bluetooth is a communication protocol which operates at the 2.4GHz range,This is a radio-frequency range and is similar to many other contracts of communication including the very utilized WiFi protocol.

Bluetooth communication structure includes a single main device, which can connect to up to seven other devices. Each slave station communicates serially with the master station, and the communication between slaves can only be completed through the master station, which plays the role of a mediator. Bluetooth devices cover a range of 1 centimeter to up to 100 meters, Maximum transmission distance in open and barrier-free environment is 15 meters.

Each Bluetooth device can maintain a low power consumption mode in idle time, thereby reducing energy consumption. In order for two Bluetooth devices to communicate, their unique code must be exchanged. Therefore, communication between two Bluetooth devices can only be carried out with the approval of the user.

In the process of Bluetooth receiving, please do not close to other transmitting signal devices, such as routers, high-power power supply, etc., because it is easy to cause signal interference.


Bluetooth Circuit


Bluetooth Circuit


A Bluetooth circuit is the central part of a Bluetooth and contains components such as the integrated circuit, capacitors and source of power. The IC contains a charger and voltage regulator. The Bluetooth module includes information on the configuration and the setting.

Bluetooth technology replaces the method of wire and cable communication between devices.

Bluetooth circuits work by using radio signals. Bluetooth circuit effectively replaces infrared technology, which is a great progress of infrared technology. It also effectively solves the limitation that infrared technology can only connect two devices.

Luckily due to technological advancements, the Bluetooth circuit uses low power signals to avoid any interruption from the other devices. That is, therefore, the reason why most Bluetooth devices only work within a range of 10 meters out of which the connection can be lost.

A complete Bluetooth circuit board must contain antennas that help send and receive information. Bluetooth circuit must include at least two inductors, whose function is to fine-tune the impedance of antenna to improve performance.

There is another auxiliary circuit board in the speaker. It connects audio cable, power button and USB power supply. The auxiliary board is equipped with two LEDs.

The presence of a printed circuit board close to the antenna may lower the resonance frequency. And so it is recommended that the thickness of the PCBs used in Bluetooth should be about 1,6mm.

In Bluetooth circuit board design, we recommend that you do not place any metal, including copper, near the area marked with GND, and that GND pins need to be connected to the plane. Switching the vias could be done to avoid any emissions from the PCB.

Bluetooth Circuit Board Kit


Bluetooth Circuit Board Kit


The Bluetooth circuit has a board kit that ensures you effectively play music or any other content that's from your phone. That achieved wirelessly through advanced technology. The Bluetooth circuit board is available in three formats:

• As a single entity.

• With 65mm speakers.

• With 100mm speakers.


The Bluetooth circuit board ensures seamless audio quality and connectivity as it is a vital part of the Bluetooth devices. It is the central part that controls the entire device. Without this kit, the connectivity and complete functionality of the Bluetooth device would be paralyzed.


It is light in weight thus being advantageous in the sense of manufacturing different devices. That means that whichever the device you decide to design, you can easily incorporate the Bluetooth circuit board kit. It is used in both the small and large devices.

The interface for the circuit board kit is easy and straight to the point. The design of this kit is in such a manner that it tries to connect to the last device that it was paired to whenever the Bluetooth in the device is turned on again.

In cases where the device it was last paired to be off or not available, the Bluetooth circuit board kit is programmed to try and match with another device that is close to it or within its range.





How To Make A Bluetooth Device Circuit?- Suggestions from professional PCB manufacturer and assembler in China


In making a Bluetooth circuit, you would need to start by creating a schematic for the circuit. In coming up with the schematic, you may need to use the software. According to the schema that you have, you can then get the necessary components that will help you to complete the circuit.

After that, you can connect the components following the lines that are in the schematic diagram you have. Your project can only succeed if you have the right schematic diagram. It shows the importance of the schematic.

One other thing that you need to factor in when making the Bluetooth circuit is the user interface. It is because the Bluetooth circuit is all about the user and how they will use it to achieve their needs.

You need to produce a Gerber file after you are done, which you can then send to the manufacturing company for the Printed Circuit Board of the device. After verification of the design, the manufacturer then prints the circuit board.

Different types of devices utilize Bluetooth technology. Generally, the headsets use smaller speakers.

The PCB layout is the most challenging part for starters. If you can create the design for the PCB, then you are good to go.

Different layouts could be used to assemble a Bluetooth circuit; however, you need to have a Bluetooth head start, switches, amplifier, LEDs, and an enclosure. Ensuring that cables do not cross the head start is essential since it reduces Bluetooth range.

Also, the system should not be placed anywhere near transmitters because they impact and affect transmission.

Once all the required components have been assembled, you should then solder wires and the LEDs soldier the on and off wire onto the headset’s PCB.

Notice that it is possible to design the PCB to be used in your Bluetooth stereo. First, you need to choose the PCBs design that you are interested in. You also need to determine the number of layers that you need to have.

For Bluetooth, you need to have more layers. You should then assemble the following materials: epoxy, cotton paper, and epoxy.

Tips for Bluetooth Circuit Board Assembly

When mounting the components, check the components type number and consolidate them to optimize their use. Once you are through with the placement, you can solder them by reflowing. You may use the infrared lamp or an oven to do this job.

Once the solder melts, it will permanently connect the components on the board. If there are components that cannot be mounted by the machine, it should be done manually.




How to Design a Bluetooth Low Energy PCB Circuit Board ?


Designing a new Bluetooth product, or any wireless product, can be somewhat challenging for the inexperienced. This is primarily due to the complexity of the PCB layout for the RF ( radio frequency) section. Fortunately, in BLE microchips, most of the RF circuitry is internal, so you don't need to worry about much more than the layout for the antenna.

Bluetooth Low Energy is a very popular open wireless standard for short-range communication. The range is typically about 50 feet, although this can be significantly increased with the use of a range extender circuit that either increases the receiver sensitivity, increases the transmission power, or both.

As the name implies, Bluetooth LE is a low-energy version of "classic" Bluetooth and thus is more appropriate for ultra-small devices powered by a single watch battery. BLE is the primary wireless technology for Internet of Things (IoT) products.
