SMS Advertising System based on bladeRFx115 and OpenBTS or yateBTS

I bought a bladeRFx115, I want to use it to learn openBTS, yateBTS, GSM, etc., I used to compile the kail yateBTS, compiles without error, but the phone is not receiving a signal, and I downloaded kalibrate-bladeRF this program, also compiled successfully, but no signal is scanned, I really do not know where the problem lies, I would like to ask people to help me, and taught me how to operate it, how to use it to intercept GSM text messaging, how to speak to them, this very fun... You may need remote assistance to me,thanks
