BLE modules use the 2.4 GHz band (2402 MHz -- 2480 MHz). It has 37 data channels and 3 advertisement channels, with a 2MHz spacing.
In the same way as Bluetooth classic modules, other BLE modules can be identified by their MAC address and public name. Also, the RSSI is provided to show the quality of each link.
Related API libraries: WaspBLE.h, WaspBLE.cpp.
All information on their programming can be found in document: Bluetooth Low Energy Networking Guide.
All the documentation is located in the Development section in the Libelium website.
