Hi Thomas, have you done C programming during your study? Do you start the bsc_hack process yourself? How much knowledge do you have about GSM? How much can your supervisor help you? As this is supposed to be the work for your bachelor degree and the issue is pretty basic, and there are examples of this on the webpage, I think you should take the time to search for it. If you have specific questions regarding the sourcecode, or how we interpreted the GSM protocol, magic numbers in the code or such please come back to us. regards holger
