Description
AT-09 Bluetooth 4.0 UART Transceiver Module CC2541 Compatible with HM-10
The AT-09 is a module that contains a BLE chip (a CC2540/CC2541). This module allows performing serial communication with the BLE chip thanks to an Rx and a Tx pin. This module is also very similar to the HM-10 module and is also compatible with it. So if you have some experience with the latter, you will get started quickly with the AT-09.
This small size Bluetooth 4.0 TTL transceiver module allows your target device to communicate with your iPhone/iPad, IOS 6 or Android 4.3 above devices. You can set it as a slave or master and use AT command to set the baud rate.
HM-10 and HM-11 series Bluetooth module use TI CC2540 chip, configure 256KB space and support the AT command. Users can change the role (master, slave mode) and the serial port baud rate, equipment name, matching password and other parameters on-demand. It is very flexible to use.
The most complete, most convenient, and most stable Bluetooth data transmission, remote control and data acquisition module. Master-slave in one, transparent transmission, replacing the serial port. Remote control, transparent transmission, MCU is unnecessary. Remote data acquisition, transparent transmission, MCU is unnecessary.
