My experience with FSO sending the command through mickeyterm was that once was enough, and the setting would remain over multiple calls. I wouldn't have tested over suspends though. After the initial patch to add %N0187 to the initialisation in qtopia based phone apps people started complaining that the echo was gone in the first call, but back in subsequent calls. Since the AT command in question is undocumented we don't know what might reset it, or even if it's supposed to last over multiple calls. There is no known way to query the current setting either. This is one of the reasons I'm asking if we can have more documentation on this now the GSM firmware is being looked at again. Until someone manages to find out how it behaves, or is supposed to behave, setting echo suppression and noise reduction for every call seems to have a lot of gain for little cost. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Also the buzzing noise is still very loud... Any suggestions? For what I read in : http://n2.nabble.com/GSM-noise-%22buzz%22-issue-tc675090.html I think I can write 2 things : Firstly : there is a difference between : - echo cancellation (what we want) - echo suppression (no transmission when no one talks) Even if http://downloads.tuxfamily.org/3v1deb/openmoko/libficgta01vendor-echo-cancellation.so.tar.gz ends with 'cancellation', are we sure we are talking about that ? Some older posts in this thread mentioned 'echo suppression'... Secondly : the buzzing noise is due to RF (radiofreq) parasites, and seems to be a hardware problem (related to the jack, because plugging a jack increases the noise a lot more). As long as we do not have a software fix (like for GPS/SDcard) or a hardware easy-to-do hack, maybe we should use a bluetooth earset because it seems to be a valid solution, cf. last messages in mentioned thread.

Thanks for this. I've installed it this way:

# mv libficgta01vendor.so libficgta01vendor.so.orig
# mv ~/libficgta01vendor.so .
# /etc/init.d/xserver-nodm restart

full re-boot does);
during outgoing call one now hears some noise like you have sometimes

when I change in gsmhandset.state the section 'control.4' to values
control.4 {
comment.access 'read write'
comment.type INTEGER
comment.count 2
comment.range '0 - 127'

The patch is against the latest snapshot of Holgers qtopia git. commit: 09335e76e1762b97dad23b997978424ed10f8da1 Unfortunately this version doesn't load the gmshandset.state file when a call is initiated. When compiling with this patch a new libqtopiaphonemodem.so.4.3.2 is created. I replaced this lib with the one on my OM2008.9. Instead of compiling it yourself you can download the file here: http://danielnoethen.de/libqtopiaphonemodem.so.4.3.2 Just replace it with the one in /opt/Qtopia/lib and restart qtopia with: /etc/init.d/xserver-nodm restart In combination with this gsmhandset.state file the volume of your calling partner is loud enough, and vice versa. http://danielnoethen.de/gsmhandset.state It should work with every distro that uses qtopia-phone-x11_4.3.2 and a device that has the calypso modem. -- Lorn 'ljp' Potter Software Engineer, Systems Group, Qt Software, Nokia Pty Ltd ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Not to defray this patch, but this is very calypso specific, and not part of the GSM spec. (although any other modem would most likely just spit out an error) Yes, I assumed something like that. I've looked at the ficgta01 phonevendor sources but didn't find a method that is called on every initiated call where I could put those two lines. This patch is only meant as a temporary bugfix until some more experienced qtopia programmer (maybe you? ;)) finds a better place for the echo suppression lines. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Hang up 6. /etc/init.d/xserver-nodm restart 7. Make a call - no echo 8. Hang up 9. Make a call - echo . . .

Here it comes, I never modified it BTW. One of the tests I have not yet
had time to carry out, is whether the echo cancellation is still on
after a suspend / resume by GSM event cycle. It would be great if you
could report back on that.

Re: Echo issue on OM2008.08 solved
Clean install off OM2008.08-update + opkg upgrade (no updates as the newest image flashed). Installed you package with -force-downgrade. strings libficgta01vendor.so | grep N0187 prints out the desired AT command, so it's the right lib for sure. Switched of the phone. Booted it up. Prevented it from going to suspend, just to be sure nothing reinits the calypso. Echo still persists as before. :/ ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

On Saturday 30 August 2008, Yann SLADEK wrote: Hi, does your patch work with a FreeRunner ? The patch turns on the echo and noise suppression capabilities in the GSM chipset using one of the hidden and NDA's AT commands someone kindly posted on the hardware list. I've tested it on my Freerunner under FSO and it works. Since GTA01 uses the same chipset I expect it will work there as well. Note that the post to the hardware list doesn't have full documentation of the functions so we may not be using the best or most reliable method of switching this function on, but for me at least it is a big improvement. if yes, why are we able to cancel the echo by setting some values under gsmhandset.state here : http://lists.openmoko.org/pipermail/community/2008-August/028465.html See my explanation later in the same thread. It sounds like the echo suppression in the GSM chipset is using a noise gate and level control similar to the one built into the Wolfson audio chip but not used in the current alsa state files. Note that even with the patch if you turn up the earpiece volume and the mic gain high enough there will be echo. The mic will pick up enough of the sound from the earpiece to fool the system into thinking you are speaking. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

On Sunday 31 August 2008, Geoff Ruscoe wrote: Is this installable on 2008.08 w/ upgrades? It should be. This package just contains a dynamically loadable library which is loaded by the qpe process. If it breaks your phone functionality, just connect via ssh and replace the package with the one from the repositories. Also I just noticed this says gta01 and I have a freerunner. And sorry for my previous sloppy top post w/ included comments... It says gta01 because the source code for the library was obviously developed some time ago. It applies to both phones, as the only piece of hardware this library depends on is the GSM chip (which should be the same, but information regarding the GSM chipset is VERY sparse). I promise, I never harmed a top poster in real life :-), I just try to educate people that sending mails like this makes reading them quite unpleasant.

I installed the package (raster+om2008-updated) and the echo did decrease quite bit. Unfortunately it was still there though, but very faint. Adjusting my mixer/state settings to those specified in another thread removed it completely but other levels were too soft. I think the settings were probably compensating too much and could be backed off a bit. Not sure which levels to alter but it'd probably be a good idea to get the guys from the other thread in on this as they are actively modifying the values to eliminate the echo. It's looking like a combination might be the way. Thanks. Sarton ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
