EM7455 Gives different address using DHCP client and reports different address while reading from run-time setting

IoT Modules MC/EM Series
1

Hi all,

We are using em7455 in one of our product with liblite QMI SDK from sierra and “GobiNet” & “GobiSerial” driver. It was able to connect to network correctly and get the IP address using DHCP client. Surprisingly, IP address assigned by running dhcp client is different then on we got from using API call to get run-time setting for active PDN. Below I am marking all important info in bold text. Can anyone explain this anomaly?

Appreciate you help !!!

Please check AT!CUSTOM? and enable DHCPRELAYENABLE. From AT guide:

1—Enable. DHCP requests (packets for port 67 with target IP address of DHCP
server) go out over the network.

This is what my configuration looks like now. Is there a lite qmi api to do this?

Also, I don’t see any difference in behavior with this changes.

Does the GobiNet driver needs to be configured differently? FYI, I am using linux kernel version “3.12.37”. Is there any tricks that need to be run for raw ip mode. I know for sure that I am using raw ip mode.

The CUSTOM setting will take effect only after a modem reset via AT!RESET. Have you tried after a reset?
You can use lite qmi API “pack_dms_SetCustFeaturesV2” to set CUSTOM settings.

Thank you @anon56110884

I still(After executing at!reset) see the same issue.

Hi @Dhruval, the QMI IP, mask and GW IP are all same which is not correct. Are you testing with a live network or test network? If a test network, could you please test with a live network and check for the issue? If you still see the issue with a live network, could you please post your AT!GSTATUS? and AT+CGCONTRDP after you start your data session. Thanks
