The module supports standard ブルートゥース transparent transmission mode and multi-connection functionality, equipped with rich peripheral interfaces (UART, I2C, SPI, I2S, PDM, PWM, ADC, 等), making it flexibly adaptable to the design requirements of various IoT terminal devices.

Whether for wearable devices demanding long battery life, health monitoring instruments requiring stable data transmission, または スマートホーム gateways needing concurrent multi-device connections, the FSC-BT630B provides stable, 信頼性のある, and low-power wireless connectivity solutions.

Ⅰ. Core Features

1.1 ブルートゥース Transparent Transmission Universal Mode

The FSC-BT630B comes pre-programmed with フィジーコム’s standard transparent transmission firmware, supporting UART transparent mode. Users can complete module configuration and connection management with simple AT commands, eliminating the need for in-depth knowledge of Bluetooth protocol stacks and significantly lowering the development barrier.

• Ready-to-Use Firmware: Power-on ready, send/receive data via serial port
• AT Command Set: Supports complete functions including module configuration, 接続管理, and parameter query
• Data Buffer: Built-in data caching mechanism ensures no data loss during high-speed transmission
• Baud Rate Range: 1200bps ~ 921600bps, adaptable to different application requirements

1.2 Multi-Connection Function Application

Leveraging the enhanced features of the ブルートゥース 5.2 仕様, the FSC-BT630B supports establishing stable connections with multiple slave devices simultaneously, serving as a Bluetooth gateway or hub node to aggregate and forward data from multiple sensors.

• Concurrent Connections: Supports connecting multiple Bluetooth slave devices simultaneously (actual number depends on the application scenario)
• Native Multi-Role Support: Firmware supports both Central (Master) and Peripheral (スレーブ) 役割, automatically adapting to the application scenario without requiring manual user configuration
• Data Aggregation: Collects data from multiple nodes centrally and reports it to the host MCU via UART

Ⅱ. Typical Application Scenarios

Scenario 1: Health Monitoring and Wearable Devices

In the medical health and wearable fields, miniaturization, 低消費電力, and reliability are core requirements. The FSC-BT630B, with its ultra-compact dimensions (10×11.9×1.8mm) and low power architecture, perfectly fits portable devices such as pulse oximeters, thermometers, スマートバンド, activity trackers, and ECG patches.

Scenario 2: スマートホーム and Automation

スマートホーム devices require stable, 低電力, and easy-to-integrate wireless connectivity solutions. Leveraging its multi-connection capability, rich interfaces, and +4dBm transmit power, the FSC-BT630B is ideally suited for whole-home smart experiences. It is widely used in scenarios like smart lighting, thermostats, door/window sensors, security detectors, and home gateways.

Scenario 3: Industrial and Environmental Monitoring

Scenarios such as industrial monitoring, environmental sensing, and cold chain logistics require large-scale deployment of battery-powered sensor nodes, demanding extremely low power consumption and high reliability. The FSC-BT630B’s low power characteristics, serial port wake-up mechanism, and wide operating temperature range (-40℃ ~ +85℃) ensure stable and reliable operation even in harsh environments like industrial warehouses and cold chain transportation.
