【Low-cost module & serial communication】DX-BT37 module is a cost-effective, ultra-low power Bluetooth module developed and produced by PDDAXLQUE. It supports BLE 5.2 protocol. Through UART serial port transmission, the device can communicate with the Bluetooth of mobile phones or computers. You can control and monitor your devices through mobile phones or computers, making your devices smarter and more convenient.The open transmission distance can reach 180m, and supports multiple serial port baud rates: 2400, 9600, 19200, 38400, 57200, 115200, 230400, 460800, 921600.
【Ultra-low power consumption】DX-BT37 has ultra-low energy consumption, it can be as low as 82.01uA when working and 1.02uA when hibernating, also can make your device achieve extremely low energy consumption, and can be powered by button batteries, making your device to adapt to more usage environments.
【AT Command】The DX-BT37 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 comprehensive technical support, including technical documentation, AT command sets, module footprints, reference design schematics, and development/test tools. To help you quickly verify module functionality and accelerate product development, we strongly recommend purchasing a development kit with your initial order. Additionally, click the Product Guide and Documentation links below to access user guides, complete product information, and product tutorials.
【Strong anti-interference ability】 The module supports onboard antenna and external antenna, equipped with RF shielding cover, strong anti-interference ability, anti-static, and EMC electromagnetic compatibility.
