RM530N-GL on AOSP 10 (Kona) – RIL integration OK, but no network

balcarekj · September 3, 2025, 4:00pm

Hello, we are working on the integration of the RM530N-GL module with the C865 dev kit on AOSP 10 (Kona platform).

So far we have managed to:

Integrate the GNSS driver (GNSS functionality works without xtra/suppl).
Integrate the Quectel RIL (v3.7) – the modem is detected in Android, and we can see operator name, signal strength, registration status, etc. in the UI and logs.

The issue is that no data connectivity is available – there is no internet connection in applications, and also no IP connectivity at the kernel level.

From the USB device tree we can see that the drivers are loaded correctly:

option driver for multiple /dev/ttyUSB ports
cdc_mbim for /dev/cdc-wdm0 and rmnet_wwan0
the rmnet_wwan0 interface appears and is in running state

However, even though the modem seems attached and recognized, the system never establishes a working data session (no IP assigned, no traffic).

Could you please advise how to:

Properly enable automatic data connection on AOSP with your RIL,
Verify the correct initialization procedure for PDP context activation (APN assignment, CGACT, QMI/MBIM sequence),
Debug why the rmnet_wwan0 interface stays without usable connectivity.

Please help check

logcat -b all | grep RILJ
logcat -b all | grep DATA_REG

balcarekj · September 4, 2025, 7:36am

I have attached the logs below. From what I can see, the module reports NOT_REG_MT_NOT_SEARCHING_OP with reasonDataDenied = 7 during DATA_REGISTRATION_STATE requests. It looks like the modem is not registering to the data network. Also logcat for RILJ fails wit errors on some steps. Could you please advise how to resolve this registration issue?

Bean.Wang-Q · September 4, 2025, 8:54am

NOT_REG_MT_NOT_SEARCHING_OP normally it means not registerred.
Please send the complete log.
logcat -b all
We need to see the AT command and the DATA_REGISTRATION_STATE at the same time.

balcarekj · September 4, 2025, 10:07am

It seems that I was able to make some progress with the registration state, but the data connection is still not working. I have attached logs for RILJ/DATA_REG /ALL.

It stay the same. For the Android it is still not registerred.

Bean.Wang-Q · September 5, 2025, 3:41am

It is using this AT command to judge whether it is registerred.
If you still using the NDK driver, I am not sure whether it can work. Or maybe we need a customerized version.
I think it is working if it just register in LTE network.

Added more logs and observations from my setup. Could you please check them and let me know if it’s correct or I’m missing something obvious?

On the kernel side:

rmnet_wwan0 is created and in UP BROADCAST RUNNING state
Only link-local IPv6 is present, no IPv4 assigned
RX/TX counters stay at zero (no actual data flow)

rmnet_wwan0 Link encap:Ethernet  HWaddr 2a:b8:b6:0f:fc:8a  Driver cdc_mbim
          inet6 addr: fe80::28b8:b6ff:fe0f:fc8a/64 Scope: Link

So it looks like the modem is registered and PDP context is active, but the data channel is not properly brought up on the system side. Could you confirm this observation?

My question:

On AOSP 10, should this normally be handled by the Quectel RIL / netmgrd stack?
Or is it expected that I use something like quectel-CM (or other service) to manage the data call explicitly?

Any recomendation would be very appriciated.

We don’t need the quectel-CM on Android.
It seems that DSDS is enabled.
Please check
getprop | grep -i multisim
And in LTE, the singal strength is very poor.

balcarekj · September 8, 2025, 9:28am

Modem was configured as DSDS, but switching on SSSS did not solve problem. Please see the attached log excerpt – from what we can tell, registration and signal information are reported correctly, but the data setup fails and rejectCause=7 is returned.

logcat_radio.txt (19.3 KB)

Could you clarify:

What is the expected behavior on AOSP when the module registers to LTE/NR?
Should the interface configuration (IP, DNS, routes) be handled automatically by the RIL/service, or is it necessary to configure these parameters manually?
Do you recommend any additional configuration steps to bring up the data connection?

What would you suggest as the next step to resolve this issue?

Thank you for your support.

Bean.Wang-Q · September 8, 2025, 11:07am

Yes. It is expected now. The IP address and router is set by the RIL. I just sent some patch for reference. Hope it can help you.
I need the full log.

balcarekj · September 8, 2025, 2:11pm

Thank you very much for the patch. I will try to apply it and see if it helps.

balcarekj · September 15, 2025, 9:38am

I have applied the patch you provided with the new Quectel driver (version 3.7), and it seems there has been some progress. However, the initialization sequence (adapter configuration) still cannot be fully completed.

I am attaching the logs from logcat -b radio (covering the init phase / IN_SERVICE).

Would you be so kind to advise me on how I can proceed further?

Additionally, could you please confirm whether it is possible to use this RIL driver (3.7) together with IRadio 1.4, or if you have a driver version available that supports this?

I would greatly appreciate any guidance or recommendations you could provide.

Thank you in advance for your help.

At least we can see the Android try to set up data call. But failed.
We can see the signal is quite bad.

balcarekj · September 16, 2025, 7:42am

The signal is indeed a bit weak, but via AT commands I can correctly read out +CGPADDR with the assigned IP. If I switch the mode and use the module purely as an Ethernet adapter without RIL, data works fine as expected.

Should the current drivers (tested 3.7 and 3.5.73 from patch) already support IRadio 1.4?

Do you have any suggestions on what else could be causing setup fail, or how I could debug it further?

Bean.Wang-Q · September 16, 2025, 8:18am

It’s not a problem of the IRadio verion. As I think the IRadio 1.0 is enough.
Here is the IRadio 1.4 libs.
QuectelWB/Quectel_RIL at IRadio1.4

balcarekj · September 16, 2025, 8:53am

Thanks for the reply. I agree IRadio v1.0 should be fine, but I’ll try updating anyway. Any suggestions what else I could log or check?

Bean.Wang-Q · September 16, 2025, 12:00pm

I don’t want try PPP. I think qmi should be better for RM530N.
Is the qmi_wwan_q driver there?

balcarekj · September 16, 2025, 12:28pm

qmi_wwan_q driver should be registered in AOSP:

cdc-mbim should be working also.
