When I use NeronGPS and a map is missing, it seems as GPRS _tries_ to get online but that's all ;-) I never tested on demand mode. Now i see that there is a bug in original qtopia. When pppd is started in ondemand mode its not opening serial port (as designed). QPE expects its to be open and start to write to the closed tty and hangs. Bug is somewhere inside QPE pppd manager, if i will have some free time i will fix it, it is trivial (e.g. - by initing serial port before running pppd). There are 2 other related bugs: 1) Default gateway is already set to 192.168.0.200 (usb), so traffic never comes to pppd. as far as i remember - linux support weight for the gateways, so fix is also trivial, but will require some work. Another bug is related to indicator - it doesnt work correctly in on demand mode, showing irrelevant status. Probably also not too hard to fix. * Staying online over a longer period of time seems to lead to a complete failure of the GPRS-stack so that I have to reboot the Neo to be able to get online again. I believe that this was fixed by me - GPRS session used the same ID numbers as Voice calls. I found that when fixed voice calls with active GPRS. Patch is done and probably will be in next qtmoko release. * Choosing always on leads to the phone trying to get online after booting and then hangs on the QtMoko-startscreen (after entering the PIN) when it tries to get online. See above. May be i will fix this, but not sure if i will have a free time. Fix is trivial, looks like nobody tested ondemand mode at all, bug is inside QPE core. GPRS Status fix may be will get some more time, i`m not really understand how this indicators works :) But i`m afraid ondemand mode, especially if i`m in roaming :) * I meanwhile managed to immediately switch to the internet settings after rebooting the phone (hard-reset) and deactivate the GPRS-connection before QtMoko managed to get online. You can ssh to the phone, delete default route (route delete default), add ppp0 as defroute (route add default ppp0) and ping any host - pppd will open port and system will be alive again :) If you want to test the fix - write me to samm at os2.kiev.ua and i will send you modified libs. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Yes, it happens some time. You don`t need to reboot the NEO btw, restarting qtmoko should help. * Choosing always on leads to the phone trying to get online after booting and then hangs on the QtMoko-startscreen (after entering the PIN) when it tries to get online. I don`t think that always on is a good idea for qtmoko. First generation GPRS and voice works very bad together. I`m recommending to switch it off when not used. * Starting the phone without SIM does not work. After trying to switch to the GUI it just stays on a black screen. I tried that to prevent the phone going online. Non gprs related :) * I meanwhile managed to immediately switch to the internet settings after rebooting the phone (hard-reset) and deactivate the GPRS-connection before QtMoko managed to get online. Its very easy to do by removing chat script using SSH connection to the phone. P.S. I believe that some of the problem are related to openmoko multiplexer, but a lot of them - to the ancient modem with first generation gprs. I`m now trying to get qtmoko running with external demuxer, to see if it will improve the situation. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

I`m now trying to get qtmoko running with external demuxer, to see if it will improve the situation. I wonder if that may explain why I have never been able to authenticate successfully to ATT's GPRS network here in the states (maybe they're blacklisting older hardware?) I'm also having trouble translating their network settings information to what QtMoko accepts. If anyone's gotten it to work, I'd love to know what you did. I can supply the connection settings if that helps.
