Newell Shenzhen Electronic Technology Co., Ltd. As a professional supplier of Bluetooth module to replace the data cable short-range wireless communications technology, Bluetooth support point-to-multipoint communication and Bluetooth module proofing, wirelessly home or office in a variety of data and voice equipment connected into a piconet (Pico-net), several piconets can be further interconnected to form a distributed network (scatter-net), in order to achieve quick and easy communication between the connected devices. Bluetooth interface on an embedded digital signal processor OMAP5910 implementation, DSP of the analog signal is sampled, and a digital signal A / D-converted processing, Bluetooth interface to transfer to the receiving end, similarly, DSP Bluetooth received the digital signal is D / A conversion, an analog signal. Bluetooth signals Bluetooth transceiver module. The company recently launched a Bluetooth module is to follow the standard Bluetooth V1.1 wireless signal transceiver chip, the main features are: a chip digital radio processor DRP (DigitalRadioProcessor), numerically controlled oscillator, RF transceiver chip switch, built-in embedded ARM7 type processors. When the received signal, the switch is set to receive the reception state, the radio frequency signal from the antenna to receive, via a Bluetooth transceiver transmitted directly to the baseband signal processor. The baseband signal processing, including down-conversion and sampling, using a zero-IF architecture. Digital signals are stored in RAM (capacity of 32KB), the ARM7 processor for call processing and, after the data output from the processed ARM7 coded interface to other devices, signal development process is the reverse process signals received, in addition, further comprising a clock and power management module and multiple general-purpose I / O ports for different peripherals. The host interface can provide a common serial duplex, you can easily and PC Bluetooth RS232 communication module suppliers, but also can be buffered serial communication and DSP. Snyder International Ltd. Shenzhen Branch Newell Newell Electronic Technology Co., Ltd. Electronic Technology Inc. is a professional custom single-sided, double-sided, 2-40 layer plywood professional supplier, providing customers with high-precision, high Shenzhen circuit board quality Bluetooth module manufacturers, quality assurance, reasonable price. Software design of the system has three, depending on the applications and systems responsible for the program using different design methods, in general, a simple system can use conventional software design methods; more complex system may use DSP simulation software CCS DSP / BIOS design methods provided (DSP / BIOS is embedded software design methods specifically for TI's DSP design); the most complex systems require the use of embedded operating systems design. Currently, OMAP5912 supports operating systems including WinCE, Linux, Nucleus and VxWorks and other Bluetooth module, you can choose a different operating system as needed, the system uses conventional software design method to achieve the most simple and convenient. Bluetooth module supplier, Yibin Bluetooth module, create Newell Newell provided by Shenzhen Electronic Technology Co., Ltd. Newell Shenzhen Electronic Technology Co., Ltd. (www.yipcb.com) (www.yipcb.com) strong, credible, in Shenzhen, Guangdong printed circuit board industry has accumulated a large number of loyal customers.
