Dorhea 3PCS BLE 4.0 Bluetooth Module AT-09 for Ardu-ino CC2540 CC2541 BLE Serial Wireless Module Compatible with HM-10
The master-slave module has three functions of transparent transmission, remote control and PIO acquisition. It can be switched and set through the AT command set. It is easy to use the same as the Bluetooth serial port module you have used before, without changing the PCB and the lower computer program..
Support AT command, users can change the serial port baud rate, device name, pairing password and other parameters as needed, use flexible..
Support UART/I2C interface, and support SPP Bluetooth serial port protocol, has the advantages of low cost, small size, low power consumption, high sensitivity of sending and receiving, etc., only need to be equipped with a few peripheral components to achieve its powerful functions..
This module is mainly used in the field of short-distance data wireless transmission. It can be easily connected to the Bluetooth device of the PC, or the data between the two modules can be intercommunicated..
When the Bluetooth connection is not established, the baud rate, name, and pairing password can be set by the AT command. After the setting, the parameter is saved after power-off, and the Bluetooth connection automatically switches to the transparent transmission mode..
