I've worked with the PLS8-E for a while but I've never manged to crash it; now I got an "illigal EMM state" at "AT+CGATT=1". - (have not managed to reproduce).

Device info and config:

Hello,

to fully diagnose this problem we would have to use tools that are covered under NDA.
To proceed with this you would have to contact your supplier to aid you with getting those tools and getting in touch with our customer service.

Illegal EMM state is most likely due to for instance broken RRC link or failed handover/redirection/reselection between 2G and 4G (weak signal for instance or sudden loss of signal).
This is just a suspicion - we would need module internal logs to fully investigate this problem.
