Yesterday e run terminal and i got its logs files from two devices i runed i will attach it here for you including configuration file.
We already contacted sale last week and no solution til now. i hope with those files you could provide solution for us. we are talking about 5 devices that are nor sending data.
Checked your configuration and log files.
I see GPS, see GPRS, but device hadn't save record, in log I see that
[2017.04.24 21:06:04]-[APP DATA SAVING]-> 2890 seconds before periodic record save
So it must have some saved records at the moment
Third log is the same in log file i see that there aren't data, but log was take 3 days ago, so now it must have info
The second log files, shows more interesting things. that device cannot make data link with server.
My first suggestion would be to change data saving period in "unknown on stop" to 60s, so would be easier to make tests.
And check are you using correct port, because it looks that one device cannot create data link with server.
Second suggestion to use newest firmware, because this one kind of old.
Attaching here newest FM11 family firmware(pass: 1234)
Please update devices, set your config and set min period in unknown on stop to 60s and when make new log files.
So I could tell you more, what could be wrong.
