Bluetooth is an open wireless device technology standard for exchanging data over short distances from fixed and mobile devices(using short wavelength radio transmissions), creating personal area networks (PANs) with high levels of security. The Bluetooth baseband protocol is a combination of circuit and packet switching. Slots can be reserved for synchronous packets.

Each packet is transmitted in a different hop frequency. A packet nominally covers a single slot, but can be extended to cover up to five slots. Bluetooth can support an asynchronous data channel, up to three simultaneous synchronous voice channels, or a channel, which simultaneously supports asynchronous data and synchronous voice. Since we are talking about mobile phones here, it is much more really great to know how really bluetooth circuit works on cell phones circuit Isn`t it nice to know, so that we can easily managed how to fix it since it is our main reason in this tutorials by learning how to repair damaged cell phone devices. In mobile phones Bluetooth problems also occurs when the bluetooth circuit is damaged, Some new cell phone techie find it hard to fix bluetooth for not knowing how the circuit works. Okay, lets tackle it for a while in just very simple explanation so that all of those without any background in electronics might can catch up too, and then we can use it in our everyday job on GSM field. Figure the bluetooth circuit block diagram below for it shows how the Bluetooth Circuit works according to each corresponding parts or components that is being connected to it. The bluetooth transceiver module is packed into chip or IC (integrated circuit), this chip needs a certain power supply to make it work. All the data that has been transmit (send) and receive from the bluetooth antenna and bluetooth RF...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
