I have EM9190 with the following parameters,

I set the Band to NR5G ALL

Why does CREG? command returns 0,0? What could be the possible reason? Please note, I connected the antenna to the module.
The response for the COPS command is
+COPS: (1,“IND-JIO”,“JIO”,“405869”,12), what does 12 convey? I understand it meant the type of access technology. So, what does 12 refers to here? What are all the other things I need to configure for this module to work, for it to transfer data?
Did you set correct APN in at+cgdcont?
Did you try latest FW?
Can it register LTE network?
For detail of +COPS, you can see:
We didn’t set the APN first. After you comment, I have set the APN. And below is the output response.
After this command, I checked the CREG? command, still getting 0,0 as response.
Regarding the firmware update, we are confused between choosing the right firmware. In the provided link, there are 2 Generic carrier firmwares available.
Our requirement is, the module should be able to transfer data irrespective of the carrier chosen.
Before setting the Band to NR5G ALL, the module was in LTE mode. And I was able to register the network and received 0,1 for CREG? command.
Couple more questions,
I got 99,99 as response for AT+CSQ command. If I get the antenna running, will the network register? If so, what should I need to do to get the antenna up?
You can set to at!band=0 and then establish data connect to ping 22.214.171.124, and check in at!gstatus? To see if it is in 5G ENDC mode
What are the AT commands and procedures to establish data connection in EM9190?
Do you have any reference document/guide to follow?
did you install the MBPL USB driver?
You can use MBIM command to start the data establishment:
i used MBIM command to establish data connection in linux PC:
owner@CNHKG-EX-001367:~/legato/workspace/git/mangOH_2-7-2019$ cat /etc/mbim-network.conf
owner@CNHKG-EX-001367:~/legato/workspace/git/mangOH_2-7-2019$sudo mbim-network /dev/cdc-wdm0 start
Querying subscriber ready status 'mbimcli -d /dev/cdc-wdm0 --query-subscriber-ready-status --no-close'...
[/dev/cdc-wdm0] Subscriber ready status retrieved: Ready…
Depends on operating system for data connection. Also did you select 5G with “AT!SELRAT=20”
