RS232 to PC via Bluetooth Module - Wireless Converter

This board enables wireless replacement of traditional serial cable connections. The installation is simple and does not require extensive changes to the existing solution.

The Bluetooth-Serial board includes a Bolutek BLK-MD-BC04-B module (located in the bottom right corner). It features a DB9 connector for RS232 and uses a USB cable for standard 5V power supply.

It works with any Bluetooth device using standard Windows drivers. The pairing process is very straightforward. In slave mode, the Bolutek module appears as an additional Bluetooth device on the computer, with a preset pairing code of 1-2-3-4. Once paired, it provides standard Bluetooth profiles for Serial Port Profile (SPP) and creates virtual COM ports.

Main Features:

• Utilizes standard Bluetooth communication protocols without the need for driver installation for Windows or Linux.
• Easy to use without advanced technical knowledge.
• The CSR Bluetooth chip supports Bluetooth 2.1 with improved BER ratio and adaptive frequency hopping.
• The user can configure board parameters such as bps, BT name, etc., using AT commands.
• Supports Bluetooth Serial Port Profile (SPP).
• Portable power complies with Bluetooth Class 2 standards with a built-in high sensitivity antenna, communication range up to 15 meters, even through walls.
• Mini USB power adapter.
• RESET button to clear paired devices from the adapter to connect a new Bluetooth device.
