Assistance with another project (with ipod accessory protocol)

[pondy]

Hi,

I'm currently working on another project (PodEmu) to have my android phone emulate an ipod. I'm stuck with command 0x13 - I believe my head unit is requesting the supported lingos(?).

With the received command:
FF 55 0E 00 13 00 00 00 15 00 00 00 00 00 00 00 00 CA

I'm not sure of the correct response to the command, could anyone please assist?

I can't help you directly, but there are some documents describing the actual serial port based accessory protocol floating around if you haven't seen them.

A lot of the documentation appears to talk about how a dock/accessory should communicate/behave. I am having trouble finding code/help on how to emulate an ipod.

The docs talk about an ipod dock and command 0x13, but not how the ipod ACKS these commands.
