Hi there people!
I would love to make use of your expertise for my little project
My englsih isn;t to good so bare with me
Controlling my tablet (or other android powered device) with the mediabuttons in the car.
ELM327 -> bluetooth -> from china
Laptop with putty for read outs
11bit canbus (i think ) so #6 or #8 on atsp command
The multimedia buttons can bus messages are sent over a secondary can bus, which is called the multimedia canbus. So what i did is switch from pin 6 and 14 to pin 12 and 13. I did this by hacking up the BT ELM dongle.
Baud rate 9600
The commands I used for initializing:
ATSP6 (0 doesnt auto detect, and I did use 8 as well..)
ATCRA 601 (which is the header of the multimedia keys canbus controller)
The output i keep getting: (xx = something..)
601 xx xx ff ff ff ff ff ff < DATA ERROR
The first 'xx' is i think de key ID the second 'xx' begins at somewhere about 10, and keeps counting until '00' only to count from there again.
So the question is: what am i doing wrong? I read the entire manual from ELM327 but can't seem to find the answers..
Thanks in advance!
Ideas and discussion of what to do with the CAN Bus ( i.e. XMDirect, iPod, Carputer, etc... )
