【Ultra-long transmission distance module】The DX-BT27 module is developed and manufactured by PDDAXLQUE. It uses Renesas DA14531 chip + PA amplifier, ultra-long distance data transmission Bluetooth module.The transmission distance between the master module and slave module can reach 580m, and the transmission distance between the mobile phone and slave module can reach 240m. 【UART Serial communication】The DX-BT27 module Through UART serial port transmission, the device can communicate with the Bluetooth of a mobile phone or computer. You can control and monitor your device through a mobile phone or computer, making your device smarter and more convenient. The module supports multiple serial port baud rates: 2400, 9600, 19200, 38400, 57200, 115200. The module serial port transmission speed can reach up to 10kbs. 【AT Command】The DX-BT27 Bluetooth module has a variety of AT commands. You can use AT commands to query and set the parameters of the module, such as: set the device name, set the baud rate, set the UUID, set the transmission power, set the broadcast time, command disconnection, restart, etc. (You can check the information to get more AT commands). You don't need to develop the Bluetooth program again, it helps you quickly develop and verify your products. 【Complete information】We provide complete information, including: technical document, AT instruction set, module package diagram, reference design diagram, development and testing tools, etc. We also provide module development kits, it can help you to quickly verify the module functions (it is recommended to buy a development kit for the first purchase) to help you use the module and develop products faster. 【Multiple Certifications】DX-BT27 module has passed CE, FCC,SRRC certifications, making your product safer and more reliable. The module supports onboard antenna and external antenna, equipped with RF shielding cover, strong anti-interference, anti-static, EMC electromagnetic compatibility. 【Technical Support】We are a manufacturer, not a trader. Please trust our ability and technology. We will help you solve the problems you meet. We also support OEM and ODM services. If you have any questions, please contact us and we will solve your problems in time. 【Note】The DX-BT27 Bluetooth module supports the BLE protocol. You cannot search and connect directly with your phone. You need to use your own APP or the test APP we provide to search and connect. You cannot search and connect directly through a computer or notebook, you can buy our master module or CP11 adapter to connect to the module through the serial port software.
