Check the cables extra carefully that comes with the BT Module! Red and black power wires may or may not be reversed. I've seen both...
Hi and thank you for joining! My first guess would be the power supply. The car electric power is very noisy and that can cause problems. I had some communication...
Fingers crossed :-) I think you could try to power it with a powerbank via USB. (Easier than resoldering stuff for a test) I wonder if it's the voltage regulator...
Ok... did you try driving the arduino from the computer ONLY? (Disconnect 12v cig and 12v RUN, and connected GND through DIN cable)
Do you get any text except "calling HU"? If not then I suspect the main init sequence is not performed successfully. Maybe it doesn't pull the busy line low enough?...
Ok. It can be really frustrating and take a lot of time finding what's causing the trouble. But since it has worked something must have happened. Which means it is...
Yes maybe it's the HU, I have a 650 myself. No play in the HU connector? If you wiggle it I mean. Anyways, you should see almost 5 v on...
Hi again! Hang on and I'll check what my DIN output measures at the end of the cable...
Yes, As I suspected I measured 4.7 volts at all three lines (In car, arduino end of cable, disconnected from arduino. I have an extra pair of DIN plugs so...
Good! It is a good thing that your HU is healthy. It is much easier to fix the cable. I use a shielded network cable with 4 twisted pairs in...
