Ok bad news ezx-hciattach is not working with your phone model.
We need to rewrite this command after stracing some binaries.
Maybe there is also a chance to load a self compiled bt module and work with a standard hciattach. I will try this next.

Can you report your phone model if it is A1200 e/i , E6 ? or what ever and which firmware you are running please.

My phone Motorola a1200 (without i,r,e). firmware ap:R541L7_G_11.00.16R bp:541_G_11.52.14R

To write a new ezc-hciattach I need some strace information please.

First if you do it over telnet and on some konsole application you need to set the path for libraries. You do it with:

. /home/native/.profile

After this run the strace command. It is not included in every firmware so I suggest to download the advanced ekonsole. If you do it there you dont need to run the home native profile. Now we come to the command:

strace -v -o /mmc/mmca1/strace.txt -s 999 -fF -x /usr/SYSbt/mbtsrv

The command will hang so after 3 seconds terminate it with ctrl+c.
And please attach the strace.txt from your sdcard here.
Thx.

My strace.txt in attachment.

Your strace.txt looks not complete.
It ends when the first child process should start. Did you interrupt the command?

When I was interrupting the strace command after some seconds I get at the end of file the following:

272 --- SIGINT (Interrupt) @ 0 (0) ---
272 +++ killed by SIGINT +++

and your file ends with:

281 wait4(282,

and should go on like this:

281 wait4(282, <unfinished ...>
282 getpid() = 282
282 getrlimit(0x3, 0xbeffeaa0) = 0
...

You can also try to strace: mbtsrv -s 1
or : mbtsrv -n 1

But on my phone it makes no differenz.


One of the child process is mbtload. So with your strace.txt I cant see how it will be executed.
So when you didnt get a full strace file try to strace this command:

/usr/SYSbt/mbtdload /dev/ttyS1 1 921600 <mya1200btaddr> 1 0 -1

Now the strace.txt is good.

It seems that the control characters from termios structure is different. I dont know so much about serial programming but when I am right changing the control characters should work for you.
When I leave off work I will compile a new ezx-hciattach.

[Halftux]

Here is the new ezx-hciattach for L7 A1200e firmware. Please have a try I hope it works for you.
Unpack an replace with /mmc/mmca1/local/sbin.

[khlystovav]

Nothing has changed.

Hmm that is realy sad maybe it is the bton not ezx-hciattach which makes problems.
I will try to investigate more.
