i updated the GC2 panel too a 1,10,1 and then updated too a 1.19.3 will this work for a new 4G LTE module or ?
1.19.3 is the latest update for the GC2 and would support either Verizon or AT&T LTE modules.
(there is an a newer version of firmware but that only applies to the brand new GC2e encrypted sensor version)
ok so I did not need too install anything inbetween
between 1.10.1 and 1.19.3
Nope. You should be good to go!
