Hi Sir, I am wondering do you have experience with HC05 before? I am using the same python code you wrote for HC05, I don't know why HC05 is paired up but I cannot see the data print in the shell.

Hi Sir, I directly connected the RX TX 3.3v and Gnd of RN42 to arduino UNO and power the UNO. But I don't know why I cannot find it by using hcitool scan. Would it be possible that my bluetooth module was burnt while I solder it ?

PLEASE TALK and explain.. The music is nice but not worth sticking around for.
