I'm not sure if I would rely on persist alone. I use a combination of hardware and software watchdogs [1] to implement reliable callback. If I call the phone from a specific number it does not play the ringtone: instead it hangs up and initiates a GPRS connection. When that is up it sends the IP address and some extra information to my server. This is quite reliable for me. I operated openmoko as an RTK-GPS base station with this setup for months without having physical access. [1] I use three watchdogs: 1) normal watchdog package that talks to the hardware via /dev/watchdog 2) custom perl script that verifies that the GSM is associated with a cell 3) a custom perl script that keeps the battery charged at around 60% to prolong its life and to also shutdown the system safely if power is lost for and the charge drops below 20%. _______________________________________________ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
