Low-Energy Bluetooth (BLE 5.0) Wireless Communication Networking Module
I. Bluetooth Modules:
Guangxi Tongtai Communications’ Bluetooth modules are proprietary products developed to meet the functional requirements of various application scenarios. A Bluetooth module is a short-range wireless communication hardware component that integrates the Bluetooth protocol, enabling wireless connections and data exchange between devices on the 2.4 GHz frequency band. Its core components include an RF transceiver, a baseband processor, a protocol stack, and interface circuitry.
Operating in the 2.4 GHz ISM band and utilizing FHSS frequency hopping (1,600 times per second) with GFSK modulation, these modules offer strong resistance to interference. They support master, slave, and master-slave combined roles, enabling point-to-point or point-to-multipoint communication.
II. Core Capabilities:
Wireless connectivity, multi-protocol compatibility (GAP/GATT/SPP/A2DP, etc.), AES-128 encryption, master/slave switching, remote configuration/upgrades. Classic Bluetooth data rates of 1–3 Mbps; BLE at approximately 1 Mbps; coverage of 10–100 meters (depending on power level); BLE sleep mode power consumption in the microampere range, with a button cell battery providing months of battery life.
III. Application Scenarios:
• Smart Home: Home appliance remote control, lighting control, door lock integration.
• Wearable Devices: Data synchronization between fitness bands/watches and smartphones.
• Industrial IoT: Sensor data acquisition, wireless device debugging.
• Healthcare: Data transmission from heart rate/blood pressure monitoring devices.
• Consumer Electronics: Bluetooth headphones/speakers, wireless keyboards and mice, game controllers.
