EHS5-E GSM Mode, ignore UTRAN | Telit Cinterion IoT Developer Community

Hello.
I'm trying to force the EHS5-E to use only GSM **** and ignore UTRAN. We have an inhouse GSM installation and I don't want to switch it to bad quality UTRAN outside of the building.
ATI
Cinterion
EHS5-E
REVISION 02.000
I tried with:
AT+COPS=1,0,"Providername",0
This switches for a moment to GSM and then back to UTRAN, checked with AT+COPS?
I tried also to add the provider to the preferred operator list with:
AT+CPOL=1,0,"Providername",1,0,0
How can I force the EHS5-E to use only GSM?
Thank you!
Hello,
You can use AT^SXRAT command to set the preferred radio access technology: AT^SXRAT=1,0. The preferred technology is non-volatile and will also be used after reboot. But this does not guarantee that the module will not register to the non-preferred RAT. With this command you can also set the current RAT but you will have to set it again after restart.
You can also configure the radio bands with AT^SCFG command (parameter "Radio/Band"). However you need to know that if the selected value doesn't contain any GSM or WCDMA band the first valid GSM or WCDMA band will be added automatically. This setting is also non-volatile.

Hello Bartłomiej
Thank you very much for your fast response! I tried it already and it seems to work. Time for a long-term test now.
I use the command AT^SXRAT=0,0 to enforce GSM and do it also after every restart of the module.
Hello Stef,
Please, how do it to perform the AT^SXRAT=0,0 after each restart?
Thanks
