Can you check the 12 V battery voltage? If it dropped too much, the device will go into Hibernate mode and that turns off the GSM/4G module.
For example, I have set that AutoPi will go to hibernate at 12,1 V. I get an e-mail (I’ve set up triggers for waking up, going to sleep and going to hibernation) and I get e-mails that AutoPi went to hibernation because of low battery voltage ({“event.system.power.reason”:“battery_level_critical”}).
My 12 V battery is in a pretty bad shape but Hyundai refuses to exchange it. I guess it has to come to a state when my car won’t start anymore
Have you tried deleting old SMSes? There’s a thread somewhere here where this was the problem.
2G/3G/4G modem couldn’t save any more SMSes (apparently it saves 255 messages) and then it stops responding.
Also on second note, try calling the number. If that works, it may be a full inbox.
is there a solution for this issue?
I used to be able to wake up from sms, but given the suggested solution still no luck waking up the device with sms. calling the number works fine.
I have tried 10 variants of setting up the job, but none seems to work. Could you please tell me what i exactly should put in the fields?
Run on start = true
Cron schedule = ?
Function = ec2x.sms_format_config value=1 (?)
Arguments: Should the be used instead?
Returner = ?
There is a temporary number assigned, which is subject to change when the SIM is power cycled. Calling the phone number doesn’t work; calls and SMS do not go through.
Yep, I don’t have any GSM/LTE coverage in my underground garage, but I have wifi… Is it possible to Wake On Lan? Or similar way to get the device running without possibility to send SMS. Anyway, how users of Autopi wifi wake their devices?
Currently there is no external wake up through WiFi.
When the device is sleeping the WiFi connection is deactivated,and as such the only way to wake up the device is either through a change in voltage,or by sending an SMS to the SIM card in the AutoPi.
