مميزات خاصة

  • 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, device name and other parameters according to their needs, flexible to use. It has the advantages of low cost, low power consumption, high receiving sensitivity, etc. Only a few peripheral components are required to realize its powerful functions.
  • Multiple Connection Methods：1. Can search connection Manually; 2. With MAC address code, it can scan QR code for connection. Compatible with Android/iOS. Please note that the slave module cannot communicate directly with the computer. It requires the master module to connect to the computer and use the computer serial port assistant to communicate with the slave module.
  • 3 Working Modes: Normal working mode. Low power mode. Hibernation mode.Bluetooth version: BLE 5.1.Working Voltage:3.3V/5V.Transmission rate:10K Byte/s.
  • Wide Application: You can quickly add Bluetooth functionality to your Arduino project, and then you can use an Android/iOS phone to control some small tools. This module is mainly used for wireless transmission of short-range data, such as Bluetooth wireless data transmission, smart home, intelligent educational devices, device monitoring and wireless control, measurement and monitoring systems, industrial sensors and controls, tracking and positioning
  • Customer Service:Our products have multi-layer packaging protection: needle guiding sponge, electrostatic bag, packaging bag. It can maximally prevent the product from being damaged during transportation. Out of the box, plug and play. In addition, we provide English technical manual electronic document for customer research. If you encounter any issues, please contact us, and we will resolve your issues within 24 hours.

وصف

Bluetooth Module Parameters:
DIALOG 14531 main control chip
Bluetooth BLE 5.1

Slave module Visible distance: 70M
Master module Visible distance: 15M
Transmission rate: 10K Byte/s
Working temperature: -40-+85 ℃
Have CE, FCC, SRRC certification
Module serial port default parameters: 9600bps/8/n/1 (baud rate/data bits/no parity/1)

Power Supply Stability Requirements:
It is necessary to ensure that the input voltage is not lower than 2.8V.

Power Down Requirements:
Since the working current of the chip of this module is very low, when the power is disconnected, if the IO port of the peripheral MCU has a weak current supplying the module, the module is likely to be in an abnormal working state at this time, so after disconnecting the power of the module, the MCU is connected to the module All IO ports must be configured as pull-down.

Hardware Design Layout Recommendations:
The DX-BT24-A Bluetooth module works in the 2.4G wireless frequency band and uses an on-board antenna. The standing wave ratio (VSWR) and efficiency of the antenna depend on the placement of the patch. Various factors should be avoided as far as possible to the wireless signal transmission and reception.
