Awful non functional LED lights advertised as bluetooth module

This is an awful product. I tried multiple times with 2 different modules but both of them refuse to enter AT command mode . The modules look okay but what is the point if they don't work? I feel like i got ripped off I don't want these to work like led lights without the wireless feature.
