Bluno Link - A USB Bluetooth 4.0 (BLE) Dongle

USB BLE-Link is a compact USB Bluetooth 4.0 adapter designed for reliable BLE communication between computers and embedded development boards. This USB BLE dongle adds Bluetooth Low Energy connectivity to laptops and desktops, enabling wireless data transmission, configuration, and programming of compatible modules. Based on the TI CC2540 chipset, this wireless programming adapter supports transparent serial communication and master‑slave configuration for flexible development workflows. Compatibility extends across DFRobot BLE platforms including Bluno - An Arduino Bluetooth 4.0 (BLE) Board and Romeo BLE (Arduino Robot Control Board with Bluetooth 4.0), making the compact adapter suitable for rapid prototyping and wireless embedded system deployment.

Bluetooth 4.0 Low Energy Connectivity

This USB BLE communication module integrates the TI CC2540 Bluetooth chip and operates in the 2.4GHz band, supporting Bluetooth Low Energy (BLE) v4.0 while remaining backward compatible with earlier Bluetooth standards. The compact USB form factor enables quick installation on PC or Mac systems without additional hardware. Efficient GFSK modulation and low‑power BLE architecture provide stable wireless communication for embedded applications, data exchange, and remote debugging tasks across short‑range development environments.

Wireless Programming for BLE Development Boards

This BLE programming adapter enables wireless firmware uploading and development workflows when paired with compatible BLE boards. Used alongside DFRobot platforms such as Bluno and Romeo BLE controllers, the adapter functions as a PC‑side wireless programming bridge. Such capability allows program updates without physical serial cables, simplifying development setups in robotics projects, remote sensors, or embedded prototypes where direct USB access is inconvenient.

Transparent Serial Transmission & Flexible Configuration

This Bluetooth serial communication module supports transparent UART data transmission, enabling wireless replacement of traditional serial cables. Dual USB‑BLE adapters can establish point‑to‑point wireless communication for stable data exchange between systems. AT command support enables BLE parameter configuration, debugging, and switching between master and slave modes. XBee‑compatible pin layout further improves integration flexibility with various embedded modules and development platforms.

Suitable applications include wireless programming environments, serial cable replacement, robotics communication links, BLE development experiments, and Arduino-based embedded projects. The compact wireless adapter also fits laboratory testing setups, rapid prototyping systems, and low‑power IoT communication experiments requiring stable short‑range Bluetooth connectivity.
