Typical application circuit

UART Interface

Four signal pins are used to realize UART function. When DX-BT24 is connected to another digital device, UART_RX and UART_TX transfer data between the two devices.
The remaining two pins, UART_CTS and UART_RTS, can be used to implement RS232 hardware flow control, and they are both active at low level, that is, transmission is allowed at low level, and transmission is stopped at high level.

3 Operating Mode

Normal working mode	All functions and peripheral interfaces can be used normally
Low power mode	When not connected, Only open broadcast, all peripheral interfaces are closed
Low power mode	In the connected state, all functions and peripheral interfaces can be used normally
Hibernation mode	All running RAM blocks of the module are closed, and only the tick clock inside the chip is reserved for wake-up. Broadcasting and all peripheral interfaces are closed

You can find out all resources related to DX-BT27-A bluetooth module from our offical website. Including testing software, drivers, software reference source code, technical manuals, AT Command documents.

Wireless communication between devices and mobile phones

Compatible with Android/iOS

Step 1: Connect DX-BT24-A Slave module to the device through the TTL interface;

Step 2: Install our Android testing app onto the Android phone, open the transmission interface for searching and connecting; Or download "LightBlue" or our company's "DX-SMART" app from the Apple Store and use it for data transmission testing

Step 3: After searching for the Bluetooth name, click on the name to connect; Or scanning the device QR code by "ScanConnect", a "drop" sound indicates successful connection;

Step 4: After connecting, data exchange can be carried out.

Technical Support: Out of the box, plug and play. You can find out testing softwares,user's manuals,devlopment documents,and all resources related to this bluetooth module on our offical website. If you encounter any issues, please contact us by email, and we will resolve your issues within 24 hou. 3 Working Modes: Normal working mode. Low power mode. Hibernation mode.Working Voltage:3.3V-5V. Transmission rate:10K Byte/s.Module serial port default parameters: 9600bps/8/n/1 (baud rate/data bits/no parity/1). Notice: The slave module cannot communicate directly with the computer. It requires a master module to connect to the computer and use the computer serial port assistant to communicate with the slave 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). You can quickly add the Bluetooth feature to your Arduino project and then you can use your Android phone or iPhone to control some devices. Feature:DX-BT24-A Bluetooth module uses the DIALOG 14531 chip. Bluetooth BLE 5.1. Support AT commands, users can change the serial port baud rate, bluetooth name and other parameters. The module is mainly used for short-range(about 15m in open area) data wireless transmission.If you need Long range module,please purchase DX-BT27-A bluetooth module.
