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

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,
The syntax of lastWillQos is correct - you can also omit the parenthesis. In case of lastWillRetain you should send either "1" or 1.
Could you check the firmware version on the module with 'ATI1' command?
How about other values of lastWillQos? I checked and I can set lastWillRetain 0 and 1 and also lastWillQos 0 and 1. For some reason I can't set lastWillQos 2. For now I don't know why.
