Transmitting infodata on MM-CAN

[ronald0001]

please can someone do a short log of mm-can while is playing music via bt-audio?

4D0 # 62 00 00 00 = satnav connected to canbus (means you can see radio and auxilary in in the c+ but not selectable)

2E3 # 00 = radio/satnav off
2e3 # 0A = radio/satnav on

4DB # 15 05 00 00 00 00 00 00 = shows navigation in the list of c+
4De # 22 00 00 00 00 00 00 00 = shows telefon in the list of c+ (not selectable cuz not connected)

go4it give me some traces but two of them shows me like he was calling...and the other one there he play form usb not bluetooth...so it shows me a list of songs wich i can select with up and down

4DC # 78 08 00 00 00 00 00 00 = shows USB - AUX in c+ but needs also any other id to be activated

What i found in my research is that MP3 played from USB (FL Mondeo with S&C) gives titles on ID 4C7 (MM-CAN),
Phone via Bluetooth uses 4C3, 4C6
Radiotext and Navigationtargets comes via 4C1 (MSB is multiplex-index)
Also 4B0 (Bluetooth Musik, multiplex)
4B2+4B3 Station names

on usb playing it gives you alist of the mp3 stored on the usbmemory

4c1 radiotext is i think couze you habe dab+??????
4b2 and 4b3 also cuz of dab+???
or function of mca direkt???

i will try 4B0 with the cantrace you send me...cuz your trace is only active bt audio but not showing any trackinfos...seems no song was played while you make the trace...only connect phone and set aux to bt...

Yes, Stevebe is wright - you don't get text on C+ while you have audio over BT, only MP3 over USB or MP3 in CD.

but then it sends you a list of titels into the convers...not only the played one with mediainfo
the fx can play mp3 via cd?

so i will stay on radio to show mediainfo in c+
its not so nice cuz only have one line and 8signs to show...
would be nice to have two or 3 lines...but it seems not to be possible...
maybe anyone can do a funktion for this ...hahaha

[DGAlexandru]

If you emulate MP3 (CD or USB) mode on your RaspBerry PI then you will have more than one line:
one for track name
one for album name
one for artist name

... if I remember correctly.

FX knows CD-MP3, SD-MP3 and USB MP3 (on a BT with enabled USB).
NX and Sony know CD-MP3 and USB MP3 (on a BT with enabled USB).
