I would recommend to use the MBUS-DEMO in the start instead of MBUS-CCT. Please also ensure that you power the boards using the DC jack. The USB cable is for communication and is not able to provide required power for the transmitter. Also ensure that the boards has Antenna connected and that the boards are separated enough so the receiver is not reaching saturation due to strong signals. A few meter distance should be sufficient.
