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.
