The AT-09 is a module that contains a BLE chip (CC2541).
This small size Bluetooth 4.0 TTL transceiver module allows your target device communicate with for iPhone/iPAD, IOS 6 or Android 4.3 above devices.
This module allows to perform serial communication with the BLE chip thanks to an Rx and a Tx pin.
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.
The 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.
