Question

Hello

Using firmware 7.04, how can we retreive the CELL ID via the console/CLI ?

I have tried gsmctl -K but it does not display the info

Answer 1

Does this Wiki Page help?

Yes, I found the command:

gsmctl -C

I could have sworn I tried that this morning and it failed. I will double check. Maybe it was on an older firmware.

Ok, so this gets stranger.

I tried it again, and I get an error on VERIZON network, but it does display for T-MOBILE. On devices with a VERIZON SIM, I get:

# gsmctl -C
ERROR: Couldn't retrieve data

Even though, via LuCI, it shows the CELL ID without issue.

Does the following command work for you:

• gsmctl -A 'AT+CREG?'

It returns the string in a format shown below, with one of the returned values being Cell ID:

+CREG: <n>,<stat>[,<lac>,<cell_ID>[,<Act>]] 

This modified command will give you Cell ID only in hexadecimal form:

• gsmctl -A 'AT+CREG?'| cut -d '"' -f 4

The command gsmctl -A 'AT+CREG?' returns the following:

+CREG: 2,3

Cell ID is not present.

---

+CREG: 2,3

According to the AT commands manual, number 3 indicates that the device is denied network registration. This might be the reason, why cell ID is not returned.

Can you confirm that your device is connected to the operator and has data?

Also, is this related to Verizon operator or T-Mobile as well?

Best regards,

The carrier is US MOBILE (VERIZON MVNO)

Yes I am sure the modem is registered and LTE connection is working. I can ping and run curl commands from the wwan0 interface.

# ping -I wwan0 1.1.1.1

Please provide a troubleshoot file, with the issue present.

Can you confirm that cell ID is not displayed with Verizon only, or are there other providers?

Best regards,

---

Yes. Well, I only have access to 2 carriers:  T-Mobile and Verizon.  

So far, the T-Mobile devices are able to report CellID via gsmctl. But all Verizon devices are failing to do so.

---

I cannot test this locally, thus I'd like to address it to the developers, but I need the requested file first.

Best regards,

---

Yes, I have just uploaded troubleshoot file from one of our Verizon sites

---

Thank you. It has been forwarded to the developers.

Once I have an update, I will let you know.

Best regards,

Could you check, what is the output of a couple of the following commands:

• gsmctl -A 'AT+CGREG?'
• gsmctl -A 'AT+CEREG?

These are also used, when retrieving cell ID, to be displayed in the WebUI. 

Best regards,

---

Thank you for working with me on this. Both commands give the same output:

# gsmctl -A 'AT+CGREG?'
+CGREG: 2,1,"4F00","1369022",7

# gsmctl -A 'AT+CEREG?'
+CEREG: 2,1,"4F00","1369022",7

So it seems the info is available via a different register.

Let me know if remote CLI access is still needed and I will make the arrangement.

---

No need for a remote.
