AT^SISS=0,lastWillQos Poblems | Telit Cinterion IoT Developer Community

October 1, 2020 - 3:43pm, 1913 views

I'm working with the Cinterion module ESX82.
When I use the commands  AT^SISS=0,lastWillQos,"2"  and  AT^SISS=0,lastWillRetain,"1", I have the follow error message: 

+CME ERROR: operation failed

What could be the reason? Is my command syntax wrong?


Thanks and Regards,
