Sending files over Bluetooth fails

[Dimitris Kogias]

Binary package hint: obexftp

In Jaunty, using obexftp version 0.19-7ubuntu2 I can send files to my Nokia E71/N95 using obexftp in both these two ways:

obexftp -b xx:xx:xx:xx:xx:xx -p file.pdf
obexftp -b <friendly_name> -p file.pdf

In Karmic however, both fail:

d@detritus:~/tmp$ obexftp -b <friendly_name> -p file.pdf
Scanning for <friendly_name> ...
Seen: aa:aa:aa:aa:aa:aa
Seen: bb:bb:bb:bb:bb:bb
Seen: xx:xx:xx:xx:xx:xx
Browsing <friendly_name> ...
Connecting...failed: connect
error on connect(): Invalid argument
Still trying to connect
Connecting...failed: connect
error on connect(): Invalid argument
Still trying to connect
Connecting...failed: connect
error on connect(): Invalid argument
Still trying to connect

In this case, the mobile doesn't even seem to receive the (browse? OBEX push?) request. I'm saying that because although it and the Karmic host are paired, the Karmic host is not trusted on the mobile (neither is the Jaunty host).

Trying without the friendly name:

d@detritus:~/tmp$ obexftp -b xx:xx:xx:xx:xx:xx -p file.pdf
Browsing xx:xx:xx:xx:xx:xx ...
Connecting..\done
Sending "file.pdf"...-failed: file.pdf
Disconnecting..\done

In this case the mobile did respond to the OBEX push, and once authorized the transfer "seemed" to happen - the "spinner" was moving. However the transfer fails at the end.

Update:

If I manually specify the bluetooth MAC *and* the correct channel for the OBEX FTP service, the push works:

Service Name: OBEX File Transfer
Service RecHandle: 0x1000c
Service Class ID List:
  "OBEX File Transfer" (0x1106)
Protocol Descriptor List:
  "L2CAP" (0x0100)
  "RFCOMM" (0x0003)
    Channel: 11
  "OBEX" (0x0008)
Language Base Attr List:
  code_ISO639: 0x454e
  encoding: 0x6a
  base_offset: 0x100
Profile Descriptor List:
  "OBEX File Transfer" (0x1106)
    Version: 0x0100

obexftp -b xx:xx:xx:xx:xx:xx -B 11 -p <file>

succeeds.

I confirm dimitris' workaround works (on nokia E61 at least) ,
btw how to discover existing chanels ?

[Dimitris Kogias (dimitris-k)]

You can get the current channels for all services by running:

sdptool browse <device BT address>

Same failure mode under Lucid, obexftp package 0.23-1

Status changed to 'Confirmed' because the bug affects multiple users.
