Installing FSO via neotool broke the modem: afterwards I didn't have network anymore, even not after switching FSO off again. I didn't turn on any logging yet. The next few nights I won't have time for that; I'll send a reply to the list once I've got any result from logging.

It should be quite easy. Check https://github.com/radekp/qtmoko/ Compiling on phone is possible, but it takes days, so i think cross compiling is better for you. After you are done with compiling, you can change the code and: cd build/src/libraries/qtopiaphonemodem make make install This will rebuild just the one library and you can scp the result to neo, restart QtMoko and try...

I think you could try placing them e.g. after signal quality change, so probably somewhere here: https://github.com/radekp/qtmoko/blob/master/src/libraries/qtopiaphonemodem/qmodemindicators.cpp Maybe just output the results with qDebug(), then you can use "telephonyStatus" value space to set the values - the you can display them on homescreen - similar to how "SMSMemoryFull" works.

I tried it in v47 but to no avail. I had other problems back then, so in case it was supposed to work chances are the rest of the system gave to many other problems to notice.

What I did not find is anything on tav <- timing advance / main cell only <- fixed radius from main cell in steps of 555m rxlev <- signal strength / all cells <- triangulation and in general anything on how one can access the current neighbours.

Re: How to access the modem in QtMoko
hi neil, openbmap and cellhunter use fso to access the modem, and at least in openbmaps code I have found a bit which checks if the modem is used by some other process and if not allows you to do the scanning of the main and neighbour cells. even if this becomes a bit off topic now, regarding the gsm-based location I am working on, I think that something similar could/must exist in qtmoko to get this information as already with mokofaen we have the lac and cellid of the serving cell being displayed on the home screen. this information already gives you a circular area around the serving cell where your phone is currently located in steps of 555m; so that is not too bad for a start. having neighbours or even being able to connect to other operators using roaming but to get their nearest cell would be the best and easiest way to narrow the position down even more. <--- so this is the part where I am wondering how to access this information in qtmoko, also if possible via at commands and getting the return information processed by python, which is not as nicely as with fso but it should work. for my other intends on how to investigate further why gprs is not working for my freerunner it would nonetheless be nice to have a simple way to try at commands. and in the end just use at commands to eg save power by shuting the modem down if you go to bed and don't want to be disturbed but still have a phone which wakes you up, as suspend in qtmoko works only from suspend mode only but not from turned off mode (some time delay problem). best regards and many thanks to you and radek as well and the other developers who do an amazing job (qtmoko/shr/androdi) + golden del for having the guts to go for a gta04!!! robin ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Are openbmap and cellhunter implemented yet for QtMoko? I thought they were implemented for FSO-based distributions only - i.e. SHR and FSO-based Debian - and in that case the access to the modem is managed by FSO. > Generally speaking I would like to > a) turn the modem off completely if I want to do GPS tracking only to save >power Yes, that would be a useful feature. > b) scan main and neighbour cells and still be able to receive calls to bring >my little progress on gsm-location also to qtmoko (works kind of in >shr) I think there are pieces of QtMoko that do that scanning, so the question would be how to connect those with your work.

Re: How to access the modem in QtMoko
dear neil, thanks for your answer. the reason I wanted to try sending commands to the modem directly is that I have problems setting up my gprs connection with qtmoko. Now I have found one site http://www.gsmsite.de/gprs.htm where they state the AT-commands for manual modem configuration. So I wanted to try those out. Now I have found to the packages which is needed to be able to execute "cu" which is uucp. Now I can apparently connect to the modem with cu -l /dev/ttySAC0 as I get a connected statement printed on the screen after having set the right permissions. Then the whole terminal freezes, but not the phone. So I won't be able to send any AT commands. I guess this might be be explained by your answer: there can be only one for modem access... On the other hand I think that the openbmap logger and cellhunter allow to scan your main cell and neighbour cells and allow you to make calls as well, whilst they run (even though they might not do their scanning during the call). Generally speaking I would like to a) turn the modem off completely if I want to do GPS tracking only to save power b) scan main and neighbour cells and still be able to receive calls to bring my little progress on gsm-location also to qtmoko (works kind of in shr) c) try to send some at commands to see if I can do something to get my gprs working in qtmoko/shr so if anyone has some hints/ideas, please let me know. best regards robin ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: How to access the modem in QtMoko
robin writes: > how do I communicate directly with the modem on /dev/ttySAC0? I'm not sure that question makes sense. When you're running QtMoko, there's a component somewhere inside QtMoko whose job it is to communicate with the modem, and it would be either impossible (because of locking) or unwise for some other code to try to communicate with the modem in parallel with that. If you switch QtMoko off (/etc/init.d/qtmoko stop), then you're left with a plain Debian squeeze system, and you can use any Debian squeeze tools you like to communicate with /dev/ttySAC0. > For the direct acces I tried cu -l /dev/ttySAC0 as it is stated on the > openmoko wiki site but I get 'cu command not found'. does anyone know which > package I have to install and if it is still necessary to do > chown uucp.uucp /dev/ttySAC0 to be able to access the modem? I don't know, but I typically investigate such questions by a combination of 'apt-cache search ' and searching. E.g. maybe searching for 'modem' or 'serial' at packages.debian.org would help.
