Dear @telstar924
I have sent the AT command to you for reference via Message, please check.
Dear @Silvia
Ty so much for your help ! 
@silvia I am currently in the same situation with ADB. Can you also send me info how it is now working?
Is there also perhaps a new AT command description, which describes all recent AT commands?
