Bluetooth proximity module synchronizes instrument display | ANS-BT301S

The ANS-BT301S is a high-performance, low-power Bluetooth 5.3 audio and data integrated module developed and manufactured by Ansiot Technology. This module boasts powerful low-level processing capabilities and is fully compatible with multiple mainstream protocols such as BLE, A2DP, HFP, and PBAP. The module uses UART as its programming interface, allowing users to easily read or write configurations via AT commands. The ANS-BT301S innovatively integrates high-quality audio transmission with efficient data interaction (command and pass-through modes), and, combined with its exclusive single-chip dual-stream & dual-domain simultaneous transmission technology, perfectly meets the diverse human-machine interaction needs of modern smart dashboards, in-vehicle central control systems, and commercial display systems.

Description

Product Advantages:

1. Bluetooth 5.3 Dual-Track Audio Data Parallelism: Stable support for high-speed data transmission (seamless switching between command mode and pass-through mode) and high-fidelity audio processing, ensuring communication and entertainment do not interfere with each other.

2. Comprehensive Screen Information Synchronization: Bluetooth supports real-time output of rich data such as lyrics, song titles, caller ID, and phonebook downloads via serial port. All information can be directly supplied to the terminal screen for display, significantly reducing the development difficulty of UI interface linkage.

3. Intelligent Seamless Connection and Unlocking: Supports automatic reconnection from paired mobile phones and transmits real-time signal strength (RSSI) values to the main controller via serial port for judgment, providing terminal devices with accurate near-field position awareness and seamless unlocking capabilities.

4. Deep Human-Computer Interaction and Intelligent Control: Built-in features include precise playback progress synchronization, multi-dimensional channel sound effect adjustment, AI voice assistant wake-up, and an ultra-low power deep sleep mechanism; it also fully supports headphone/speaker audio control (track skipping, volume adjustment, answering/hanging up calls).

5. Flexible Multi-Peripheral Playback Switching: The module defaults to supporting audio output from peripherals such as Bluetooth headphones and Bluetooth speakers, and can also be switched to local module output, allowing free switching between different playback paths.

6. Exclusive “One Chip, Dual Stream” Customized Function: Innovatively supports dual-domain simultaneous transmission technology, perfectly achieving seamless separation of “headphone listening, screen awareness,” allowing audio and data streams to operate independently and collaborate efficiently.
