Knot LR8G kit gps and LTE CAT M1 don't work

Hello,

I'm trying to use the GPS and the LTE module.

No matter which firmware I use, the LTE connection is often unstable. As for GPS, I simply can't establish a connection.

Are there any working configurations here yet?

Configuration
LTE: SIM Hero
GPS with aktive antenna

Firmware: 7.19.6, 7.22.3, .23rc3

Update:

LTE CAT M1 - Modem Init:

AT+QCFG="iotopmode",0,1;AT+QGPSCFG="priority",1;AT+QSIMDET=1,1;AT+CGACT=1,1
