## Features

- Feature: This is the paired version of the BT27-A master&slave module, which includes one master bluetooth module and one slave bluetooth module. It has been paired and can be directly connected after being powered on. Note: The master module can only be connected with the slave modules sold in our store, and cannot be connected with any other model Bluetooth module
- Multiple Connection Methods: 1.Can search connection Manually; 2.With 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 communication.If 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 communicate.For 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

*by D***N on 4 December 2023*

The module works as expected just like any HC-05 or HC-06 with Arduino IDE. I couldn't get the module to work with AT Commands, but it connected automatically with the slave and easily manually the app on my phone. Very good for starters who want to make a simple RC project with good range. Though I haven't tested the range claims I'm sure it works fine.
