I have been trying to solve my problems on my FXT002, FTX009, FW R7.43 modems for a while. I have created several topics about these problems. Now i have investigated a new problem.
There was a problemmatic modem on the field and i asked my customer to send it back to me. I received it yesterday. i read my custom logs which my open at software saves in flash.
According to the logs, it seems that modem software has stopped working somehow. My Open AT software checks the time in each 5 minutes and it saves a log record on midnight. So there must be at least one log record in each day.
However, there are no log records during 6 days.
- 2nd Jan through 11th Jan 07:56 -> there is no log.
- 11th Jan 07:56 through 11th Jan 23:17 -> working.
- 11th Jan through 18th Jan -> there is no log.
- 18th Jan 09:00 through 18th Jan 09:19 -> there are 47 resets! and after that there is no log until 24th Jan.
So, i suspected that something puts the modem a protection mode. As i mentioned above, there is a reset loop 47 times within 19 minutes!
The question is if there is a protection mechanism in Fastract Xtend modems and if so how can we indicate the reason why the protection mechanism occurs.
