PLS62T serial connection freezes | Telit Cinterion IoT Developer Community

I want to set up a connection on PLS62T.
After :
^SYSLOADING
^SYSSTART
+CIEV: prov,1,"fallback"
I can send AT commands aproximatively 5-10 seconds . After that , terminal freezes.
What is wrong in that procedure?
Hello,
Do you use USB or RS232? In case of RS232 it is possible that there is a sleep **** for serial interfaces active. Please check AT^SPOW? output. In such case you can switch it off with AT^SPOW=1,0,0. Or you have to use HW flow control. Please also check with AT^SCFG? if there is no system out redirected. If there is any custom MIDlet running it is also possible that it uses the interface.

Thank you very much. Yes, there are Midlets running.
Same issue:
I identified two midlets:
at^sjam=5
^SJAM: "a:/name.jad","Java Remote Control MIDlet Suite","name","1.62.04",1,1
^SJAM: "http://address.jad","SetModemFTP MIDlet Suite","name","3.07.04",1,0
The first I could stop with:
at^sjam=2,"a:/name.jad",""
but the second don't work to stop with the same comand
at^sjam=2,"http://address.jad",""
I tried to stop the second and terminal freezes.
Is there a sintax error?
Hello,
There are two factory installed MIDlets.
1. JRC - it is a part of module firmware and should not be uninstalled.
2. SLAE - it is a part of optional solution for remote management and is disabled by default. You also do not need to remove it. In fact you can't.
As JRC is started automatically in the same way as custom MIDlets userware autostart should not be disabled (^SCFG: "Userware/Autostart","1").
If the MIDlet you want to stop in none of the above you can stop it and uninstall if not needed. If terminal freezes, something may not be correct.
The URL instead of the local link just means that the MIDlet was installed remotely. It should be possible to stop it using this URL as you tried to do.
Please disable autostart by setting AT^SCFG="Userware/Autostart","","0" reboot the module and then try to uninstall it (if you don't need it) or just try if your problem still exists when it's not running.
