EHS6T startup failure - Registered Status LED intermittently flashing orange | Telit Cinterion IoT Developer Community

June 20, 2018 - 5:23am, 2358 views


Yesterday I deployed a MIDlet with JAD-level autostart configuration enabled. The MIDlet itself had an error in the code; this was something which I just realised when looking back into the code after I had deployed the MIDlet.

So the MIDlet was running, and all of a sudden the unit began acting up.

The registration status LED had begun to flash intermittently and the USB connection commenced to switch on and off; one second it was connected and the next it would fail to recognise a connection.

I attempted to fix this problem by trying the following, in no particular order:

1. Recharged data for the SIM card.

2. Removed and reinserted the SIM card.

3. Powered off and replugged in power.

4. Removed and replugged the antenna.

5. Removed and reinserted the USB cable.

I have found that none of these steps helped fix the problem which once again is that on my powering the unit on, it commences flashing the registration status LED orange and then stops, then resumes flashing, and so on.

Does this sound familiar to anyone? is it a possible firmware ********** issue or a symptom of a possible hardware breakdown? 

Is there anything software related I can try, or any tool I can use to diagnose and fix the unit on a software level that Gemalto could recommend?

It is impossible to run the unit while it is stuck in this boot loop.

As always would appreciate any advice.
