EHS6T locks (status LED stops flashing) | Telit Cinterion IoT Developer Community

I hape someone can help me out.
We have a jave midlet running on EHS6T, transferring files to and from a FTP-server and one of our own devices (Serial COM0).
At one of our customers we have the problem that the EHS6T stop working, and it ***** a reset to start again. I have done a lot of code analysing to try and find out what happenes, but haven't succeded yet.
Now we have seen it testing in house, and we see that the orange LED stops flashing.
AT^SLED = 2,10.
Can anyone tell me what state it is in when the LED stops flashing (it is constant ON)
best regards Nanna
if I check bgs5_atc documentation then I have this settings:
If you have same settings as BGS5T, then it shoulden't be constant ON with your settings only if you have AT^SLED = 1.
Have you tried adding watchdog to your MIDlet, so that application or module restarts when watchdog doesn't recive kick?
I have the same documentation on EHS6, and m setting is AT~SLED = 2,10, which is default.
I don't use the watchdog, but I have a thread that supervises other threads, and if not OK the Modem is restartet with AT+CFUN=1,1.
But I am puzled about the LED that stopped flashing. Why is that. Could something in my software make system software stop? For example if no answer when connecting to the FTP-server? I think the error occurs at some point when communicating with the FP-server.
Does the led problem happen when the module stops working or is it independent.
It would be good to check the SLED status after it has stopped blinking.
Does your application issue AT&F command? This resets the led state in release 3.
For example when MES connects to the module this command is issued.
Please check ATI1 output to check the firmware version.
What does it mean that the module stops working - it doesn't reply to at commands or maybe the application just hangs? Is it possible in your app that all threads give no output?
I think that watchdog could be more reliable than custom reset.
