В эпоху Интернета вещей, Bluetooth modules are no longer just “connection tools,” but rather the core engine for product intelligence and enhanced user experience. Whether it’s a two-wheeled vehicle dashboard, smart hardware, or audio terminal equipment, choosing the right Bluetooth module often determines a product’s competitiveness.
Below, we’ll start with three mainstream Bluetooth module types to quickly understand their core advantages and application value:
Dual-Mode Bluetooth Modules: The “All-Round Player” of Connectivity and Compatibility
Dual-mode Bluetooth (Classic + БЛЕ) balances high-speed transmission with low-power communication, making it one of the most widely used solutions currently available.
1. High-speed transmission + multi-protocol support
Represented by ANS-BT203M:
Supports SPP / БЛЕ / HID multi-protocols
Supports a high baud rate of 921600
Data transfer rate up to 80KB/s
Suitable for: Devices requiring stable data communication and human-machine interaction (such as industrial equipment, smart terminals)
ANS-BT203M
2. Strong multi-device connectivity
Represented by ANS-BT202M:
Supports simultaneous connection of 7 Android devices + 1 Apple device
Meets the needs of multiple users interacting simultaneously
Suitable for: Portable printers, delivery printers, and other multi-user control scenarios
АНС-БТ202М
3. Automatic host reconnection for a seamless experience
Represented by ANS-BT201P:
Supports automatic reconnection based on name / Automatic address connection
Power-on connection, no manual intervention required
Suitable for: “plug and play” scenarios such as instruments and meters
ANS-BT201P
BLE Bluetooth Module: The Ultimate Solution for Low Power Consumption and Multiple Connections
БЛЕ (Bluetooth Low Energy) is the “battery lifesaver” for smart devices, especially suitable for battery-powered devices.
1. **Master-Slave Integration, Strong Multi-Connectivity:**
Represented by ANS-BT101M:
Supports master-slave integrated architecture
Supports up to 9 connections
Suitable for: Шлюзы Интернета вещей, multi-device control centers
АНС-БТ101М
2. **HID Support, Seamless Interaction:**
Represented by ANS-BT101L:
Supports HID (Human-Machine Interface) functionality
Enables seamless unlocking, such as on two-wheeled vehicle dashboards
Suitable for: Smart door locks, vehicle systems, identity recognition scenarios
ANS-BT101L
3. **Ultra-Small Size, Ultimate Integration:**
Represented by ANS-BT105M:
Size: Less than the size of a fingernail
Easily embedded in various micro-devices
Suitable for: Wearable devices, portable smart hardware
ANS-BT105M
Audio Bluetooth Module: The Core Hub for Entertainment and Interaction
Audio Bluetooth modules not only “listen” but also “control,” making them a key component of smart audio devices.
1. Parallel Audio and Data Processing
Represented by ANS-BT301M:
Supports simultaneous audio transmission and data communication.
A single module integrates multiple functions.
АНС-БТ301М
2. Rich Information Synchronization Capabilities
Supports lyrics display and phonebook synchronization.
Provides a more complete human-computer interaction experience.
3. Multiple Input and Output Interfaces
Supports BT/USB/AUX/TF card input.
Output supports stereo/I2S.
Meets the design needs of various audio systems.
4. Upgraded Intelligent Control Experience
Supports playback progress synchronization and sound effect adjustment.
Supports mobile phone AI voice wake-up.
Creating a more intelligent voice interaction experience.
5. Low Power Consumption Design
Deep sleep mode consumes only 1mA.
Balancing performance and battery life.
From high-speed dual-mode Bluetooth connectivity to low-power multi-connectivity BLE modules, and then to feature-rich audio Bluetooth solutions, different types of Bluetooth modules are empowering the continuous evolution of various smart terminals.
