To preserve our connection, we have auto-reboot set as follows:-
- reboot -> 5min interval, 4 retries, ping 184.108.40.206
- modem-restart -> 5min interval, 3 retries, ping 220.127.116.11
As a fail-safe, the modem is set to do a periodic reboot at 23:30hours Mon-Sun, as these devices are out in the field. Occasionally, one of this will loose connection to the mobile network. Whilst the periodic reboot does take care of it, it may be down for several hours which is a problem for our customer.
Sometimes, we can send an SMS command to issue a "reboot" and other times, the RUT955 totally looses connection to the mobile network (so no SMS message will deliver to the device).
- Why does the auto-reboot not do it's thing when the ping fails (and we have to rely on the periodic reboot)?
- Are there any kind of log-files that will give us a clue as to what is happening in these odd occasions?
