Urgent: Need Assistance Configuring RG500Q for 5G Network

Hello,

I am attempting to configure the RG500Q module to connect to a 5G network. Below are the commands I have used and their responses from the module. Despite these attempts, the network is not connected. Could you please provide the correct method to configure the RG500Q for 5G?

Logs:

AT+QNWPREFCFG=“mode_pref”
+QNWPREFCFG: “mode_pref”,NR5G

OK
AT+QENG=“servingcell”
+QENG: “servingcell”,“SEARCH”

OK
AT+C5GREG?
+C5GREG: 0,2

OK


From the logs, it appears that the module is in search mode and the registration status is 0,2, which indicates that the network is not connected.

Your urgent assistance would be greatly appreciated.

Thank you.

Does the AT+COPS=? command show any 5G networks available?

Give the command time to complete the network scan. It can take over a minute.

I used the AT+COPS=? command, Here is the output I received:

AT+COPS=?
+COPS: (1,“IND-JIO”,“JIO”,“405861”,7),(3,“Reliance”,“Reliance”,“40510”,7),(3,“CellOne”,“CellOne”,“40471”,2),(3,“IND airtel”,“airtel”,“40445”,7),(3,“Vi India”,“Vi India”,“40486”,7),(0-4),(0-2)

OK

Hi @gopi,

your AT+COPS=? output only shows LTE networks.

5G SA networks are listed with <AcT> 12 like this +COPS: (1,"Telekom.de","TDG","26201",12),(1,"Telekom.de","TDG","26201",7),(1,"262 23","262 23","26223",12),(1,"o2 - de","o2 - de","26203",12),(1,"o2 - de","o2 - de","26203",7),(1,"vodafone.de","Vodafone","26202",12),(1,"vodafone.de","Vodafone","26202",7),,(0,1,2,3,4,5),(0,1,2)

Hi Reinhard,

Thank you for your input. I managed to get the 5G SA network on the network list. Here is the output from the AT+COPS=? command:

AT+COPS=?
+COPS: (1,“IND airtel”,“airtel”,“40445”,7),(1,“IND-JIO”,“JIO”,“405861”,12),(1,“Vi India”,“Vi India”,“40486”,7),(1,“CellOne”,“CellOne”,“40471”,2),(1,“Reliance”,“Reliance”,“40510”,7),(1,“IND-JIO”,“JIO”,“405861”,7),(0-4),(0-2)

It shows that the device can see the 5G SA network (12 for IND-JIO). However, I don’t think the device is registered to the 5G network. I tried using the command AT+QNWPREFCFG=“mode_pref” and received the following response:

AT+QNWPREFCFG=“mode_pref”
+QNWPREFCFG: “mode_pref”,NR5G

OK

But when I tried the AT+C5GREG? command, it returned an error:

AT+C5GREG?
ERROR

Am I missing some command or step to register the RG500Q to the 5G network?

Hi @gopi,

it is a bit strange that AT+C5GREG? returns ERROR instead of a proper status like

AT+C5GREG=2
OK
AT+C5GREG?
+C5GREG: 2,1,"xxxx","yyyyyyyyy",11,4,"01.000001"
OK
AT+COPS?
+COPS: 1,0,"DTAG",11
OK

Can you check whether AT+CFUN? returns +CFUN: 1 and CPIN? returns +CPIN: READY ?
In case AT+CPIN? returns +CPIN: SIM PIN enter your PIN first.
Trying a manual registration to the JIO 5G SA network with AT+COPS=1,2,"405861",12 might also help.

Hi,

when I execute AT+CPIN?, I receive the response +CME ERROR: 10, which seems to indicate that the SIM is not inserted.

I have double-checked and confirmed that the 5G SIM is properly inserted. I also tried inserting it into a different SIM slot, but I still get the same SIM not inserted error.

Could there be any other potential issues causing this problem, or any additional steps I should take to troubleshoot further?

Hi @gopi,

the only way I can produce the same error in my setup is to switch the RM500Q-AE to UIM slot 2 which is not connected in the M.2 adapter I am using:

at+quimslot?
+QUIMSLOT: 1

OK
at+quimslot=2
OK

+CPIN: NOT READY

+CPIN: NOT INSERTED
at+cpin?
+CME ERROR: 10
at+quimslot=1
OK

+CPIN: NOT READY

+CPIN: SIM PIN
at+cpin="yyyy"
OK

+CPIN: READY

+QIND: SMS DONE

+QIND: PB DONE

Did you change any AT+QSIM... settings on your RM500Q?

Reinhard
