Hi all , I made usb adld cable the easy way posted by someone on here and its great tuner pro and aldldroid both read fine , however looking at using bluetooth o do the same for builing digital dash and wondered if anyone on here had any luck building one? I have seen the redriver and 1320 aldl bluetooth devices and know I would have to import them to uk but looking at instructions for use they both say hc05 is the paired device and the bluetooth serial hco5 is £3.50 here but that only accepts 3.3v on rx and beleive aldl uses 5v? I have tried hooking one up but aldldroid just states incorrect response from ecu so guessing the voltage is an issue with rx?

any input apreciated
Thanks
