SPP+BLE5.0 Bluetooth dual-mode slave module BM77 BM78 | ANS-BT203M
The ANS-BT203M is a small-sized, high-performance Bluetooth 5.0 dual-mode wireless slave module independently developed by Ansiot Technology. It is an ideal, cost-effective solution for enterprise customers to seamlessly replace BM77 and BM78 modules. This module is perfectly compatible with BR/EDR (Classic Bluetooth) and BLE (Bluetooth Low Energy) dual-mode architectures and deeply supports concurrent transmission of SPP, BLE, and HID modes.
The ANS-BT203M module uses a standardized UART serial port as its programming interface by default, allowing users to configure parameters through flexible AT commands and supporting comprehensive, in-depth customization development.
Product Advantages:
1. Seamless Replacement for BM77/BM78, Dual-Mode Dual-Rail: Adopts a new generation of Bluetooth 5.0 dual-mode (BR/EDR and LE) architecture. Supports concurrent SPP, BLE, and HID modes, with high functional compatibility, perfectly solving the challenges of key component inventory and domestic substitution.
2. Hardcore Customization, Ultra-High-Speed Wireless Transparent Transmission: The module has undergone deep underlying optimization. In high-speed mode, the SPP classic Bluetooth transparent transmission rate can reach 70-80KB/s, and the BLE low-power Bluetooth transparent transmission rate can reach 30-40KB/s, easily handling large-capacity, high-frequency data stream exchanges.
3. Fingernail-Sized, Exquisitely Compact Size: The ultra-compact physical packaging significantly saves PCB board area, allowing easy embedding into various portable or miniaturized terminals with extremely demanding size requirements.
4. Global HID Control and iOS Keyboard Invocation: Specifically optimized for modern human-computer interaction. In HID mode, it supports one-click pop-up of the virtual keyboard on iOS devices. It also features built-in settings for 10 multiple languages, supports fine-tuning of the sending interval, and precise return connection to the target device, perfectly adapting to cross-border export devices.
5. Intelligent Name and MAC Address Binding: Supports highly customizable device names and automatically appends the last 4 or 6 digits of the MAC address to the name, perfectly eliminating the identification and pairing confusion problem in densely populated environments with multiple devices.
6. Dual Wake-up and Intelligent Low Power Consumption: Supports a scientific low-power mode and adjustable transmission power. It automatically enters low-power mode after 10 seconds of no data. It can be activated and woken up in milliseconds via an app (wireless) or serial port data (hardware), balancing long battery life and instant response.
7. Comprehensive Broadcast Features and Security Defense: Allows developers to freely configure broadcast functions (including broadcast content, broadcast interval, and broadcast address). It also includes a high-standard easy pairing mode and PIN code security verification settings, effectively isolating unauthorized connections.
