EG915U no response on AT+QNWINFO

IoT Modules LTE Standard Module

Hello,
We have an EG915U module on one of the products we’re developing. The module is driven through an ESP32S3 and we’re using the modem/dce interface. Most functions seem to work as expected however we’re unable to get a response to the AT+QNWINFO command. Once the modem registers on the network and the ppp interface goes up (we successfully get an IP from the operator) we’re trying this command to see which AcT/band we’ve managed to connect on. We always get a fail.

Any suggestions will be highly appreciated.

Could you please share your current operation procedure? what URC is returned after executing AT command? Much appreciation.

Thanks @Jonathan.wang but it seems like we’ve figured it out. We had to do a

dce->pause_netif(true);
query network info
dce->pause_netif(false);

and it worked!
