I can only point you at the bluez examples. mLinux 3 is based on Bluez 4.101:

Look in the directory /bluez-4.101/test/ in the archive.
For instance, test-thermometer is a python program for monitoring a thermometer. I have not tried these. D-BUS is the recommended infrastructure to write BLE programs.
