Comments
please comment out line 85: compile, upload and check what is on serial port please. |
commented out line 85. serial monitor: Audi Concert I Multimedia Gateway Ver.1.0b |
solved by changing line 2156. changed from SetStateIdle() |
thx! it should be probably used only with MPD control t. |
ok soi fried my arduino uno. I somehow shorted some pins while troubleshooting. I have uploaded the code to two different arduino pro minis and the unit does not change to cdc mode now when selecting CD. Is there a way for me to confirm that I am receiving data from the headunit? Or are arduino pro minis incompatible? Please help again. |
Check seial console
edit:
so pro mini can by 8 or 16Mhz, if your is 16Mhz everything is same as on nano, so code should work
but for 8Mhz, timer based functions need tweek so please check which version you have
t.

i have 16mhz but i will check serial console. so far without unit powered upit keeps repeating the aforementioned messages without the RING.It did not do this with the uno |
I found my issue. It turned out to be a wrong connection to the ground at the connector. The arduino would seem to power up and work properly but without the the ground it was never going to communicate with the unit. Thanks a million for your support. You are awesome. |
I successfully compiled, uploaded and connected the arduino to audi symphony 2. It recognizes cdc1 track1 00:00 but does not emit sound from aux nor does it have play option. Is there sething I am missing?
