it definitely is. read my writeup at http://www.teaparty.net/technotes/openmoko-2.html#GPRS if you want to see exactly what i'm doing (my writeup's about 2008.09, but it's identical to the setup i just did for 2008.12 save that gsm0710muxd was in the repository so i didn't have to get the packages manually. > I hope to last 12 hours or so, because I do GPS live tracking > with position upload to the internet every 5/10 seconds. my battery won't last that long! > But the real problem is that if the connection fails, it will not > restart again. I can add a cronjob to test connection and restart > it, but I know that pppd should manage the fault. i have *definitely* had pppd drop and autorecover the connection on shorter calls (eg, on the train - the cambridge-london line has tunnels on it, which provide a handy means of testing drop/recover). i'm not sure that pppd is handling the autorecovery, though; i have a vague feeling it's the call handling between the calypso chip and the base station(s) that are responsible for setting up my GPRS connection again). i can post my ppp and ping logs next time i see this behaviour, if you'd like, so we can see if ppp even appears to notice the outage? -- Tom Yates - http://www.teaparty.net _______________________________________________ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
