The Tinysine Bluetooth Bee v2 is a Bluetooth 4.0 Smart Ready wireless module that integrates both Bluetooth EDR and BLE chipsets into a single module. It is compatible with multiple Bluetooth versions, allowing it to work seamlessly with both Android and iOS devices. The Bluetooth Bee v2 features a compact design with an XBEE-compatible pinout, making it suitable for a wide range of microcontroller systems that provide 3.3V power output. The module supports AT commands for configuration, enabling easy adjustment of parameters such as the baud rate. An onboard antenna ensures improved signal quality and stable wireless communication. The module operates as a transparent serial port, allowing simple and reliable serial data transmission over Bluetooth. The baud rate can be modified for use with an XBEE adapter, and when paired with an XBEE Arduino controller base, it enables convenient Bluetooth wireless control for embedded applications. Note The EDR and BLE functions use different MAC addresses, as shown below: 0x00, 0x0E, 0x0B, 0xXX, 0xXX, 0xXX //BLE MAC 0x00, 0x0E, 0x0E, 0xXX, 0xXX, 0xXX //EDR MAC
