MoodeAudio to car stereo

[tommyQ]

Is there any way to connect to my cars bluetooth?  When I put the car into add device mode, it wants to provide a 6 digit code before it will pair.  I hoped putting this is the bluetooth section of Moode might work but the car regenerates a PIN.   Is there any way to get Moode to accept this code?

I got the audio throught the car speakers but only bu putting http streaming on, connectong to the stream with my phone and then connecting bluetooth of my phone to the car.  The only control I then have is pause/resume and the next track type of steering wheel controls are in this mode dead.  To be fair, I don't know if a pukker connection as I would like it would allow this, but it's what I was hoping for.  

I did see a different solution mentioned in another post about a USB C to audio cable but as far as I know, on the rPI4, the USBC is only for power and I'm using that port for that. 

I'd also spotted the possibility of a pi Zero and a DAC hat but I dont know yet if the headers align for that. It looks like id does for the pico.



Any ideas welcome - thanks in advance.  Tom

I think car head units run PIN protected Bluetooth. Connecting moode to the head unit won't work because there is no code in moode to accept or acknowledge the PIN. Moode uses bt-agent. Here's some links that explain some of its options.

IIRC most Pi car audio approaches involve connecting a pi to head unit line in and then phone connects to the pi via bluetooth or wifi hotspot. Something like that.

Thanks for the links and thanks too for the suggestion. I'll be sure to read and try the latter out. FYI I'm looking into how long a rPI can run before it starts to put a dent in my battery but also going to work out a power down switch king of thing so I dont crunch the music thats now on the SD card. Brilliant project!!
