Modul doesn't recover after AT^SJOTAP | Telit Cinterion IoT Developer Community

September 11, 2015 - 9:29am, 6953 views


We have quite some BGS5T modules in the field and some of them need to have there MIDlets updated. To do that, we can issue AT^SJOTAP command from Java code, when specific SMS is sent, normal text SMS not PDU.

Most of the ***** this works fine, but some***** it happens that module won't recover after the update. Green light will be on, but it won't accept any new SMS commands, so MIDlet is probably not running. So you need restart it with turning off and on its power supply. I couldn’t check what happens on the module at that time, because I wasn't physically there, so I don't know if it accepts AT commands or if MIDlets is running.

What could be problem for that? Even if there is some ERROR inside MIDlet Watchdog should restart it after 60 seconds. Or is watchdog maybe the problem?
