Quectel RM530NG ip address disable bridging

hubertmulewski · November 8, 2023, 12:48pm

Hi,
I have installed Iperf3 on quectel module, Id like to perform tests via iperf adb shell, but IP is bound to windows network interface, instead of rmnet/rmdata interface on the Quectel module itself, is there an option to set via AT commands mode, to not bridge IP into windows Quectel interface.

Dear @hubertmulewski
Could you give us more information about this?
How did you test and network topology?
Is it possible to disable windows network from your PC? Then test again.

hubertmulewski · November 24, 2023, 8:44am

Hi @silvia, I have disabled network adapter, sadly IP still stays on the modem, but not getting forwardeded to adb android, and we’d like to utilize iperf installed directly on Quectel, since iperf is already operational, but issue is with IP.

Dear @silvia please help support this issue

hubertmulewski · January 2, 2024, 11:30am

Hi, still problem is unresolved @silvia

silvia · January 5, 2024, 6:09am

Dear @hubertmulewski
Which network did you test? rmnet or others? Please check via AT+QCFG=“usbnet”
I saw you disable modem’s network, not PC. You can try disable your network and use modem’s network to test.

hubertmulewski · January 8, 2024, 1:07pm

Sadly I cannot disable my network interface, as its used for remote desktop access.
Here’s output

AT+QCFG=“usbnet”
+QCFG: “usbnet”,0

Dear @hubertmulewski
Actually, you want to test iperf with module, you need to disabe other network, then try if it has network or not.

hubertmulewski · January 15, 2024, 7:51am

Hi, how do I disable other network?

silvia · January 18, 2024, 5:10am

Dear @hubertmulewski

hubertmulewski · January 18, 2024, 10:27am

Yes as you can see its already disabled, what do I do else?
Disabled all other interfaces, outcome is the same:

What is the output of a command AT+QMAP="mPDN_status"

Fourth number tells which rule is connected and third number tells if IPPT is active.

You can use command AT+QMAP="mPDN_rule" to change settings.

Fourth number of the rule setting in use should be 0 to disable IPPT which would assign IPv4 address to the module.

There are additional settings which might affect this but check this first.

hubertmulewski · January 19, 2024, 8:36am

Hi,
current config is:

AT+QMAP=“mPDN_status”
AT+QMAP=“mPDN_status”
+QMAP: “MPDN_status”,0,0,0,0
+QMAP: “MPDN_status”,1,0,0,0
+QMAP: “MPDN_status”,2,0,0,0
+QMAP: “MPDN_status”,3,0,0,0

That says that you don’t have mobile network connection at all, your screenshots also tell that rmnet_data-connection is not up, that is the interface which would get the public IP.

Screenshots show only default private address 192.168.255.1

hubertmulewski · January 19, 2024, 9:34am

Heres output with assigned public addres from AT commands:

at+cgpaddr
+CGPADDR: 1,“10.42.211.178”
+CGPADDR: 2,“0.0.0.0”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”
+CGPADDR: 3,“0.0.0.0”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”

OK
AT+QMAP=“mPDN_status”
AT+QMAP=“mPDN_status”
+QMAP: “MPDN_status”,0,0,0,0
+QMAP: “MPDN_status”,1,0,0,0
+QMAP: “MPDN_status”,2,0,0,0
+QMAP: “MPDN_status”,3,0,0,0

10.XX.XX.XX belongs to private address range too.

But you should have rmnet_dataX interface up too to have a connection, lets try what ip link show shows instead of ifconfig

silvia · January 23, 2024, 3:48am

Dear @hubertmulewski
It seems this is module’s network, but you had disabled.

hubertmulewski · January 23, 2024, 8:23am

That’s correct, 10.x.x.x this is a private network used for Labolatory testing, however rest of the 5G phones are working fine within that pool.

Ok, your in the lab.

This is how things should look when mobile data link is running, module you are using doesn’t have a single interface in a UP state. I think something missing in a configuration of the module is very likely.
