I use as WinTre mobile operator and my reference bts has 4 bands (B1 B20 B3 B7) and it is 180 meters from me. I have a problem with the kit in question when I go to do either a lock on a specific cell or with the lock on a specific band for the primary.
In practice both if I try to do the command to block at the level of a specific primary cell (I use band 3 because it is the one that gives me the best upload performance compared to the other bands):
[admin@MikroTik] > /interface lte at-chat lte1 input="AT*Cell=2,3,,1650,367"
output: +CREG: 6,"5f37","03b9db0e",7 $CREG: 6,"5f37","03b9db0e",7,"0b5" +CEREG: 1,"5f37",
"03b9db0e",7
[admin@MikroTik] > /interface lte at-chat lte1 input="at*cell=1,3,,1650"
output: +CGEV: NW PDN DEACT 5
I tried to put both the latest stable of RouterOS (6.48.1) and the beta (7.1beta 3) but the problem remains.
The only way to get it working again is to cancel the commands just given with:
[admin@MikroTik] > /interface lte at-chat lte1 input="AT*Cell=0"
