Motorola A920 and Fedora ?

jcz · 01-18-2004, 05:30 AM

Hello there!

Got my c600 setup with Fedora instead of rh9, fixed my problem. I now have a question concerning my new 3g mobile handset which i have been trying to access from my fedora laptop with no success. Is there somewhere a project where integrating your mobil to your linux OS is about to be possible?

Thanks in advance!

Hi there,

did you have any luck on this project?
Does anyone have an idea of how to sync Linux (I'm using debian) with motorola a920?

old thread, but still interesting. here are some links:

Motorola A920 (is almost the same as A925) under linux over USB:
http://dev.gentoo.org/~brix/papers/A920/A920.html

... and if you want to connect to your PC via bluetooth, additionally this one:
http://a925.albatorsk.com/

how to access the phone's memory and the inserted SD/MMC card:
http://www.koeniglich.de/p3nfs.html

how to use the synchonisation features:
http://multisync.sourceforge.net/news.php

an open source ogg vorbis player

:
http://symbianoggplay.sourceforge.net/

a powerful "calculator" with many, many features (including calculating matrix, integration, differentiation, displaying graphs - makes your phone a TI92 killer):

unfortunately this program isn't free, the price is USD $29.95 if you want to get it legally.

i hope these links help,

these links are very helpful. Many thanks!

little hint: in the first howto it says you have to connect to /dev/ttyUSB0 (or to /dev/usb/tts/0 if you use devfs). for me that didn't work. i'm running debian with devfs (simply "apt-get install devfsd" and add "devfs=mount" to the kernel parameters) and the appropriate device for me is /dev/usb/acm/0.
simply add that one to you /etc/ppp/peers/A920-USB.

Hey again,
I finally got around to try to connect to my a920, and I have a little problem. I don't know where in /dev I can find the device. I'm using gentoo with devfs and I don't have any of the three devices mentioned above. Although the a920 is recognized by the kernel. Any ideas? Thanks.

hi,

this is what /var/log/syslog says when i plug in my A925:

Code:

Dec 16 15:39:09 meteor kernel: ohci_hcd 0000:00:02.1: wakeup
Dec 16 15:39:09 meteor kernel: usb 3-1: new full speed USB device using address 2
Dec 16 15:39:10 meteor usb.agent[19533]:      cdc-acm: loaded successfully
Dec 16 15:39:10 meteor kernel: drivers/usb/class/cdc-acm.c: Ignoring extra header
Dec 16 15:39:10 meteor kernel: cdc_acm 3-1:1.0: ttyACM0: USB ACM device
Dec 16 15:39:10 meteor kernel: usbcore: registered new driver cdc_acm 
Dec 16 15:39:10 meteor kernel: drivers/usb/class/cdc-acm.c: v0.23:USB Abstract Control Model driver for USB modems and ISDN adapters

because of these two orange lines (the ones where it says "ACM") i found out that the correct device for me is /dev/usb/acm/0
make a "tail -f /var/log/syslog" (or /var/log/messages) to see wheter there's something similar for you. when you post it here, maybe i can help you.
besides: did you append "devfs=mount" to your kernel parameters? and did you compile in (or as a module everything that's mentioned in the howtos?

Hey! thanks a lot for your reply. Judging from your output I should have cdc_acm compiled as well, which I don't (I'm quite sure it's not mentioned in the howto, but it seems obvious now that it's needed

)

I'll compile that module and give it another shot. I'll report here, whether I succeed or not.

Nightfrost · 12-16-2004, 11:00 AM

OK; with cdc_acm loaded the device is linked to /dev/usb/acm/0. The problem I have now, is that when I load usbserial; my a920 /dev/usb/acm/0 dissappears... strange indeed. Any ideas? Do you still want an output from dmesg posted?
Thanks for trying to help me out on this one. Really appreciate it

Nightfrost · 12-16-2004, 11:09 AM

OK OK... made I mistake. I hadn't entered the information in /etc/modules.conf according to the howto. The comments in that file, however, say that one shouldn't alter it manually but I did it anyway. /dev/usb/acm/0 is thus present but the connection fails anyway. I have Desktop suite running on the handheld and this is what pppd returns:

Code:

Using interface ppp0
Connect: ppp0 <--> /dev/usb/acm/0
LCP: timeout sending Config-Requests
Connection terminated.
Using interface ppp0
Connect: ppp0 <--> /dev/usb/acm/0
tcflush failed: Bad file descriptor
tcsetattr: Invalid argument (line 1027)

I don't even know which file is referred to here...

Nightfrost · 12-16-2004, 11:11 AM

OK, for the love of Gods!! It's getting silly now with all my posts here; but I tried to connect again and this time it worked. I don't really know why it didn't worked last time but that's alright...

anyway, many thanks..

ogott · 12-16-2004, 11:55 AM

nice to see that it works for you too. no idea what that error message meant or what file it referred to, but if it works now, it's ok.
now i have a question to you: is your connection as slow as it is for me? i'm only getting about 60 kbps over the USB cable. i know it's just USB 1.1, but it should be faster anyways. so, when i have to get data to my mobile, i use my card reader to write to the SD card directely.

I haven't configured a SyncML server yet; I haven't really checked into which clients are good for kde. But I remember during my Windoze-days, when I was using Motorola's own software for syncing, the transfer was extremely slow. So I used to do the same you do, using a card reader. I guess it's the same deal under Linux with the speed.

I'll let you know about my tramsfer rates under Linux when I get things working here...

ogott · 12-16-2004, 12:20 PM

ah yeah, i don't use that SyncML tool either, i only tried transferring data with that nfsapp tool directly to the C: or D: drive. that was quite slow.
besides, i want to state that i don't use the mobile for doing phone calls or whatever one is supposed to use a phone, but i just use it as a mp3 and movie player (it's the cheapest device that you can get here in austria that can do that - i payed € 99,- and it's prepaid, so no monthly fee). that's why transferring data is quite important to me.

Nightfrost · 12-16-2004, 12:28 PM

ah OK, I see. But then I think the best idea is to just use a card reader. What I would like to be able to do is to sync the calendar and emails.

By the way, does the oggplayer work fine for you. I tried it a while ago and I remember getting really bad sound with lots of noise, maybe I there's an updated version I should try...
