Rockbox + car adapter in advanced remote mode?

[chripopper]

Hi i've got my ipod video 5g 30gb currently running rockbox hooked up to my volvo ipod adapter, witch enables controlling of ipods on the oem stereo.

But when i try to skip tracks the currently playing song just starts to play/pause and play/pause and random does not work either, the only thing that works is play/pause except when i try to change song when it goes nuts.

I think the random function is in the advanced remote command list so i dont know if that ever will work but changing tracks should work??
I've tried every serial bitrate in the settings, turned ipod car interface on and turned that power to accessories thing on but it still wont work.

Is there any patch to this? I saw a "Alpine cd changer" plugin, should i install this as i think the stereo is manufactured by alpine (it is using M-Bus).

Thanks for any help.

Probably not a bad idea to put your results on the bug tracker under FS#9951 - Ipod Accessory bug reports.

The "Alpine CD Changer" plugin is only for the old Archos Player and Recorder targets. See this page for more info about it:

Ah ok. Found this: http://www.rockbox.org/tracker/task/8624 should i install it or is it already integrated in my rockbox version? (3.3) Any other idea how to get it working?

Is it possible to write a plugin for this? If it's not extremely hard i think i can do it...

Well for starters you could leave a bug report as I suggested to you before.  But beyond doing that and hoping someone else fixes it for you, you'd have to actually look into your hardware's communications and figure out why its not working.

Don't really understand this, isn't it one serial command for all 5g ipods to, for example change track? And one for play and so on?

I've just read this: http://www.adriangame.co.uk/ipod-acc-pro.html

And figured it maybe has something to do with the replies from the ipod, the adapter sends the command to turn the ipod to advanced control mode and wants a reply from the ipod that it is in advanced control mode. Maybe it wants reply from "Get number of songs in playlist" and so on.

If this isnt already integrated in the current build, is it hard to write a plugin that answers to all the commands i want? I have a little programming experience but dont know where to start...

No.

I've just read this: http://www.adriangame.co.uk/ipod-acc-pro.html

Including the part where it says theres multiple modes with different commands

Well for starters, you need to figure out what your device is sending that rockbox doesn't understand (or what rockbox is sending that the device doesn't understand).  You could do this by snooping on its communication with the OF or Rockbox and see if you can figure out whats getting stuck.

[chripopper]

Ok whats the OF? Please explain how i sniff so i can figure out whats wrong and leave a report and hope that someone helps me out 

I've never used rockbox before so i'm completely noob, tried to find some guides but did'nt find any..

[GodEater]

OF = Original Firmware, i.e. the one Apple installed it with when it left the factory.

[chripopper]

Ah ok how do i snoop the commands? The only way i can think of is using a ipod breakout adapter and a oscilloscope??

[GodEater]

a USB sniffing program would be a much simpler place to start.
