opensync over bluetooth for N900

Dear all,

Has anybody managed to sync addressbook using opensync via bluetooth?

syncml is responding with an error as below

Code:

 syncml-obex-client -b xx:xx:xx:xx:xx:xx 25 --slow-sync text/x-vcard Contacts --wbxml --identifier "PC Suite" --dumpinfo

Received an transport error: Link Error: 0x0

Received an transport error: Unable to get answer

Received an transport error: Link Error: 0x0

Didnt receive the devinf though it was requested

Is there any other syncing solution? I have opensync-0.22 sync beautifully with kontact with N95.
Thanks

Re: opensync over bluetooth for N900

Hi,

I experience the same problem, but have some findings that may (or may not?) help.

According to http://www.opensync.org/wiki/trunk/syncing/syncml :
1) Restart your bluetooth service.
2) Make sure the screen is not locked on the N900.

These advises do not matter for me, but anyway...

What I have found:
3) Setting the version to 1.0 with "--version 1.0" seems to help.

4) Case matters! It should be Calendar (not calendar), Notes (not notes) and Contacts (not contacts).

The closest to success I get is this:

Code:

$ syncml-obex-client -b xx:xx:xx:xx:xx:xx 25 --version 1.0 --wbxml --identifier "PC Suite" --dumpinfo --slow-sync text/x-vcalendar Calendar --slow-sync text/plain Notes --slow-sync text/x-vcard Contacts

connection with device succeeded

5) Some general advises on the net are to limit the number of changes with --recvLimit and to set the --maxObjSize. I have tried both, but neither seem to matter.

Any suggestions are welcome!

Re: opensync over bluetooth for N900

Thanks for your findings. Unfortunately i received the same error even with "--version 1.0". The libraries i have are:

libsyncml-0.4.6
libopensync-0.22
Distro: Gentoo x64

Re: opensync over bluetooth for N900

Seems like the "restart service" tip above has some substance after all. After leaving my laptop for dinner and returning again I got the exact same error as you.

Restarting the service did not help though, but restarting the bluetooth chip itself got me back to the "almost there" report above:

Code:

# hciconfig hci0 down

# hciconfig hci0 up

# hciconfig hci0

hci0:   Type: USB

        BD Address: xx:xx:xx:xx:xx:xx ACL MTU: 1021:5 SCO MTU: 64:1

        UP RUNNING PSCAN ISCAN 

        RX bytes:87051 acl:737 sco:0 events:1371 errors:0

        TX bytes:44157 acl:704 sco:0 commands:584 errors:0

This behaviour seems to be some kind of power saving "feature".

Re: opensync over bluetooth for N900

An alternative, more persistent, way for me to reliably repeat my half-way-there results seems to be to load the btusb module with the reset parameter.

Test it with:

Code:

# hciconfig hci0 down

# rmmod btusb

# modprobe btusb reset=1

# hciconfig hci0 up

If this helps make it persistent with the following line in /etc/modprobe.d/options.conf or similar file:

Code:

options btusb reset=1

I have also tried to sync via USB and get the exact same behavior...

First find a SYNCML-SYNC interface:

Code:

# syncml-obex-client -u

Found 4 USB OBEX interfaces

Interface 0:

        Manufacturer: Nokia

        Product: N900 (PC-Suite Mode)

        Interface description: PC Suite Services

Interface 1:

        Manufacturer: Nokia

        Product: N900 (PC-Suite Mode)

        Interface description: SYNCML-SYNC

Interface 2:

        Manufacturer: Nokia

        Product: N900 (PC-Suite Mode)

        Interface description: PC Suite Services

Interface 3:

        Manufacturer: Nokia

        Product: N900 (PC-Suite Mode)

        Interface description: SYNCML-SYNC

Use '-u interface_number' to connect

Then try to sync via that interface (-u 1):

Code:

# syncml-obex-client -u 1 --identifier "PC Suite" --slow-sync text/x-vcard Contacts --slow-sync text/x-vcalendar Calendar --slow-sync text/plain Notes --wbxml --version 1.0 --dumpinfo

connection with device succeeded

For USB access you need to be root though, and obviously a cable. That is why I would prefer to sync over Bluetooth if possible.

Anyone got this working??

Re: opensync over bluetooth for N900

Bumping this to check if anybody has made any progress to get opensync working with N900.

Re: opensync over bluetooth for N900

Does syncing the calendar work?

Re: opensync over bluetooth for N900

I spent a few hours I won't get back, too. Looks to me like it's not gonna work with current versions of software.

The lamest of workarounds for now, at least it's something, is getting the unoficcial MoreFunctionsForAddressBook extension for Thunderbird. On the N900, export all your contacts as vcard 3.0's. Now in the Thunderbird Contacts, use Tools > MoreFunctionsForAddressBook to import them all at once.

People are working on getting Thunderbird to synchronize with Ubuntu One for Ubuntu 11.10. Until then, you can use the unofficial Hedera Contact Sync extension. But it's so alpha and new, I haven't got a clue why it works on one and not on the other.
