QCELLOC AND QSCAN support

IoT Modules LTE Standard Module
1

Hi,

I’ve read that certain firmware versions for the Quectel EC25 and EC200 modules support a specific AT command that provides signal strength and operator data from neighboring cells.(QCELLOC & QSCAN)

I’m currently prototyping an LTE probe and require access to this command for proper functionality.

Would it be possible to obtain the firmware versions that enable this feature for both the EC25 and EC200 modules?

Thanks in advance for your help!

Could you tell me your current detailed version?
Execute AT+QGMR

HI, I probably did wrong answering to the email notification. Here are the versions requested:

I’m testing with 3 different devices;

EG25 Version: EG25GGCR07A02M1G_01.001.01.001

EC25 Version: EC25EUXGAR08A13M1G_20.200.20.200

EC200 Version: EC200AEUHAR01A21M16_01.200.01.200

Thx

Hi @Chano
Sorry for the delay. After confirming the “QCELLOC” and “QSCAN” command are not supported in these 3 modules.

You can try this command AT+QENG=“neighbourcell”

Could you please confirm wich modules support this feature??

But thats a 5G module that it’s expensive. Are there any other modules (no 5G) that supports QSCAN?

Regarfing the AT+QENG command Yes, this works, but if there’s no SIM card in the module, even when I use AT+COPS to manually select a carrier, it always returns the same neighbor cell data from a default carrier (I assume it’s the one with the strongest signal, but I’m not completely sure).

What I’m trying to achieve is to get the signal levels of neighboring cells per carrier, without the need to have a SIM inserted.

When I insert a multi-SIM that has access to different carriers, and run a loop of AT+COPS followed by AT+QENG=“neighbourcell”, the behavior is as expected: I can see the neighbor cells for each carrier.

Sorry for answering both topics in the same message, but the forum doesn’t let me post only every 40 minutes :frowning:
