Common Classifications of Bluetooth Communication Modules

In the era of the Internet of Things, 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 + BLE) 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 / BLE / 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)

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

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

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.

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
