Description
DX-BT27-A Bluetooth Module Long Range Up to 420m BLE 5.1 Support Scanning QR Code to Connect Wireless Bluetooth TF Transceiver Module for Arduino Compatible with Android/iOS
Feature?Bluetooth module name: DX-BT27-A(slave model). Bluetooth BLE 5.1 protocol. DIALOG 14531 main control chip+PA amplifier. Transmission rate 10K Bytes/s. Operating temperature – 40 +85 ?. Supports UART hardware interfaces. Module size 37.5(L) x 15.7(W) x 4.0(H) slave module is suitable for communicating with connected devices through mobile phones, and compatible with Android/iOS(iPhone)
Multiple Connection Methods: search connection Manually; MAC address code, it can scan QR code for connection. Compatible with Android/iOS(iPhone). Working Voltage:3.3V to 5V. Supported baud rate: 2400,4800,9600,19200,38400,57600,115200
Long Range: The connection distance between the BT27-A slave and the mobile phone can reach 140 meters, and the connection distance between the BT27-A master and the BT27-A slave can reach 400 meters(This distance data is the result of testing in an unobstructed and open area. If it is not within the visible range during use, please use the measured results as the main one.)
Notice: Because this module is BLE 5.1 serial port protocol module, so the PC side cannot use the built-in bluetooth or bluetooth adapter for you need to communicate with slave module by computer, it requires the master module to connect to the computer and use the computer serial port assistant to the specific process, please refer to “Use the master Bluetooth to communicate with the module” and “DX-BT24 series Bluetooth module_Main mode_ Application Guidelines”.You can find out them on our offcial website
