I have to do some tests with the EC25-EUX module and 2G network (without 3G and 4G network).
How can you set the Module to work only 2G network? Which command I have to use?
I think that may help.
+WS46 can be useful to read the modem’s RAT setting. It can’t be used to set it to 2G. The only implemented set argument effectively means “automatic”.
See 3GPP 27.007, section 5.9.
AT commands to restrict an EC25 to 2G include:
I did some tests with the AT+COPS=0, , ,0 command and I can switch to 2G.
I imagine that to return to the default settings just give the command AT+COPS=0, , ,7.
AT+COPS=0 should result in automatic mode.
AT+COPS=0,,,7 will result in 4G-only.
