How is the Bluetooth remote control system designed? ---- Huayun Industrial Bluetooth remote control manufacturer

The Bluetooth technology in the Bluetooth remote control is a short-range, low-power wireless connection technology. It provides users with a low-cost, low-complexity, high-reliability, high-compatibility wireless communication network, which can make the attached Bluetooth device convenient Fast data sharing. The Bluetooth chip of the Bluetooth remote control has a small size, low power consumption, simple integrated circuit application, strong portability and low cost Cheap and other advantages.

The Bluetooth protocol can be divided into three parts: the underlying hardware module, the intermediate protocol layer, and the high-end application layer. The underlying module of Bluetooth is the core of Bluetooth technology. It consists of a link management layer, a baseband layer, and a radio frequency layer. The radio frequency layer mainly defines the requirements that a Bluetooth transceiver should meet. Bluetooth technology works in the 2.4 GHz ISM band, which has a global data transmission rate of 1 Mb / s. The intermediate protocol layer includes logical link control and various protocols. The high-end application layer corresponds to the profiles of various application models.

The core of the Bluetooth remote control system is the Bluetooth remote control and remote control device transceiver. The Bluetooth module is embedded in the Bluetooth remote control and the remote control device transceiver to complete the communication between the Bluetooth remote control and the remote control device transceiver.

The Bluetooth remote control hardware is mainly composed of 8 parts, and its main functional modules are: 1) 2.4 GHz RF power amplifier; 2) Bluetooth module: Bluetooth module completes RF and baseband functions; 3) Microprocessor system: as Bluetooth wireless access The core components of the device, on the one hand, control and coordinate the work of various functional modules, and on the other hand, complete the Bluetooth high-level protocol; 4) LCD display: used to indicate the working status of the device, as a function selection menu; 5) input keyboard: User operation command input keyboard; 6) USB interface: communication port with data terminal; 7) RS232 interface: communication port with data terminal; 8) Battery power management: Bluetooth remote control is powered by 3 V battery.

Hua Yun remote control manufacturer specializing in customized Bluetooth |2.4G| voice, air conditioning, set-top box, infrared remote control.

The software structure of the Bluetooth remote control is divided into 3 levels: 1) the application of the remote control; 2) the device driver developed for Bluetooth devices, including Bluetooth's high-level protocols (RFCOMM, L2CAP, etc.); 3) the Bluetooth baseband part of the protocol: This part of the protocol has been solidified in the Bluetooth module.

The software and hardware design of the Bluetooth remote control was completed, and the system of the Bluetooth remote control was completed.

Dongguan Huayun Industrial Co., Ltd. focuses on the production and development of Bluetooth remote control, and can provide you with the most suitable Bluetooth remote control solution.
