and that's how it simply works.
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.
Typical block diagram of a Bluetooth CircuitThe 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 (radio frequency) transceiver is feeds in for receiving and feeds out when sending to the application processor (cpu IC). There is an RF clock which comes from the RF circuit section is also feeds into it, that certain RF - Radio frequency is also needed by the bluetooth module to make it fully functional.
Since all those certain parts on bluetooth circuit were packed only into chips. A way to truly understand how does the circuit connect with each other from each certain components is by reading the circuit schematic diagram to locate this certain components parts on the main PCB board so that we can be able to check, trace and fix when a bluetooh failure happens. here's an example of the bluetooth schematic diagram and figure out how each components connect with other. In this method you can easily identify where that certain parts connected from one another. See here:
And here's an example of the Bluetooth circuit layout of components on a PCB board.
You'll notice that all of the bluetooth components is mounted in one section and near to each other. Some important spots is being labeled for quick troubleshooting guide. Like this picture below, the voltage supply and the RF clock are being labeled for quick check up and test procedures.
