obex.sendfile doesn't work

[aptc]

I used the example on your website to test send file function:

from lightblue import *
obex.sendfile("00:1A:16:BE:50:66",3 , "MyFile.txt")

my cell phone responsed by asking me to accept the connection, when I say yes, something happened like this:

wujunbao@ubuntu:~/Desktop$ python sendtest.py
[btobexclient_connect] Connecting transport...
[btobexclient_connect] Connecting OBEX session...
[btobexclient_event] Transport link broken, terminating connection!
[btobexclient_request] OBEX_HandleInput() error!
[btobexserver_cleanup] entry.
Traceback (most recent call last):
  File "sendtest.py", line 2, in <module>
    obex.sendfile("00:1A:16:BE:50:66", 1, "MyFile.txt")
  File "/usr/lib/python2.5/site-packages/lightblue/_obex.py", line 47, in sendfile
    fileobj, os.stat(source)[stat.ST_SIZE])
  File "/usr/lib/python2.5/site-packages/lightblue/_obex.py", line 62, in _sendfile
    raise _lightbluecommon.BluetoothError(str(exc))
lightblue._lightbluecommon.BluetoothError: Error connecting to server

I printed the information to ease your debug by adding following lines in _obex.py:

        print address
        print channel
        print name
        print fileobj
        print filesize

it returned this result:

Hope this can help you imporving lightblue.

Hi, I'm sorry, I just read the thread "lightblue.obex.sendfile() : Error", the problem was same, so maybe I have to find the solution myself.

Thank you, anyway, you can delete this thread if you think that's right. I don't mean to cause you this inconvenience.

I have made a test.

From "bluetooth file sharing" of ubuntu, I can send any file to my two phones, Nokia 7500 and nokia 6670 without any problem.
Ubuntu could only receive the file sent by 7500 but not the 6670.

When I use lightblue (or openobex), no one succeed. both got above error.

How can I figure out the problem if it exists in openobex or bluez stack? give me some hints if it's possible.

Thank you!

Hi,

Try reinstalling openobex - I've had a similar problem myself and that worked for me. (Could be something to do with the version of openobex as well - I installed the latest 1.3 version and the previously installed version was 1.0.0.)

>> How can I figure out the problem if it exists in openobex or bluez stack?

Ubuntu would be using the bluez stack, so if you can send files from the built-in apps, it must be openobex. You can check the bluetooth activity using 'hcidump -X -V', to see if any obex commands are actually being sent, and turn on the openobex debug messages as well.

Hi, blammit

You are so kind, thank you!

I have run obex_test in openobex-apps to see what happen, and it showed that it's openobex's problem.

Probably there is a problem related with lightblue, everything was OK with my Nokia 6670 when I was running obex_test, but in python, bluelight couldn't receive the file from 6670, the odd thing is that Nokia 5700 could do it well. obex.recvfile(s, "MyFile.txt") didn't say anything and 6670 said: "connecting..."   and then "sending failed" when I pushed file from ubuntu to 6670!

I don't know, I am not sure, I am puzzled by waht happened to me :)

Thank you blammit!

No problems, glad you were able to sort it out.

Are you saying you can't use lightblue to send files from ubuntu to the 6670, and you can't use it to receive files from the 6670 either?  But you can do both successfully with the 5700?  That's really strange. Could you please post or email me the hcidump output and/or openobex debug messages that you get when you use lightblue with the 6670?

[aptc]

My 6670 can receive files when i sent them from the lightblue, but the lightblue couldn't receive the files sent from 6670. I'm not sure whether this is the problem of lightblue or not.

I try to turn on dubug on openobex by installing a new openobex-1.3 but failed to catch library libopenobex.so.1, so I just provide the hcidump output here.

You are so helpful, I really appreciate what you have done here, thank you!

[blam]

No worries :) And thanks for sending that, I'll check it out.

[aptc]

I use the command "obexpushd -B" to test if openobex is ok in this case, the result is positive, openobex functions very well with my 6670.

But the 6670 dosen't work with lightblue.

I compared the difference between two above hcidump data, found it's the "SDP SA Rsp:" which caused problem.

I also find the custom transport but not the bluetooth transport is used in lightblue as function btobexserver_init in btobexserver.c indicated.

Maybe above information can help you, they all related with SDP, is it possible that custom transport isn't perfact as bluetooth transport?

I think lightblue will support multi-byte character file name in near future, is that right?

Lightblue is great, I am using it to desigen prototype bluetooth products with python, it's really convenient, I like it!

It will be more great if lightblue can be used to built up real products when it's mature.

[blam]

I didn't think the custom transport would cause problems, and the Bluetooth transport shouldn't be doing anything with SDP. But I'll try and test it with obexpushd. Thanks for checking it out.

> I think lightblue will support multi-byte character file name in near future, is that right?

I'm not sure what you mean?

[aptc]

I think the problem is caused by parameter SDP_ATTR_SUPPORTED_FORMATS_LIST or SuppFormatsList, which may not be registered on service discovery database by pybluez or other later program. look the difference in the dumped data:

          cont 00

Bad connection couldn't response the SuppFormatsList data what remote device required.

[aptc]

The connection problem disappeared after I registered the SuppFormatsList data in pyblue.

> I think lightblue will support multi-byte character file name in near future, is that right? 
I'm not sure what you mean?

when the bluetooth device's name or the file's name is multi-byte character like chinese, something like this will be displayed:

Traceback (most recent call last):

    main_loop.do()

How did you register the SuppFormatsList?

That's a bad bug, thanks, that will be fixed.

[aptc]

>How did you register the SuppFormatsList?

Add following lines in program /pybluez/bluez/btmodule.c

  uint8_t formats[] = { 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0xFF };
  uint8_t fdtd = SDP_UINT8;
  void* dtds[sizeof(formats)];
  void* values[sizeof(formats)];
  sdp_data_t* list_formats = NULL;

  for (i = 0; i < sizeof(formats); ++i) {
    dtds[i] = &fdtd;
    values[i] = formats+i;
  }
  list_formats = sdp_seq_alloc(dtds,values,sizeof(formats));
  sdp_attr_add(&record,SDP_ATTR_SUPPORTED_FORMATS_LIST,list_formats);

[blam]

Yeah, the Push server really should publish the Supported Formats List. It would be great to be able to do this through PyBluez, without modifying the source. Do you think you can use this code to submit a patch to the PyBluez project to configure the Supported Formats List when advertising a service? (Just like how you can configure the UUIDs for service classes and profiles when calling advertise_service().)

[aptc]

I think it works. first, I copy these code from obexpushd; second,it made my cell phone work after modification; and third, I have checked the dump data and saw the right response has displayed.

[blam]

Oh, yes, I can see that it does work, and it does solve the problem. What I meant was, can you submit a patch to PyBluez so that the Supported Formats List can be configured through the advertise_service() function in the PyBluez library? If that functionality is added to PyBluez, then LightBlue's advertise() function would be able to use PyBluez to include the correct Supported Formats List when it advertises a service. And I'm sure PyBluez users would be pretty happy to have that extra functionality too.

[aptc]

Ok, I see, I'll try it. thank you.
