RM520N-GL eSIM adding profile

IoT Modules 5G Module

Hi,

I’m currently trying to install an eSIM profile on the RM520N-GL (slot 2) with a ST4SIM-200M. My current firmware version is RM520NGLAAR03A03M4G_A0.301.A0.301. It seems that i’m missing something, i have been trying via AT commands, with quectel lpad software and also with lpac.

AT+QESIM=?

+QESIM: “lpa_enable”,(0-1)
+QESIM: “profile_brief”
+QESIM: “profile_detail”,(1-8)
+QESIM: “eid”
+QESIM: “delete_profile”,(1-8)
+QESIM: “nickname”,(1-8),
+QESIM: “def_svr_addr”,
+QESIM: “disable_profile”,(1-8)
+QESIM: “enable_profile”,(1-8)

OK

I tried profile_brief, profile_detail, and def_svr_addr; they all return ERROR. Also, the add_profile command, which returns “Coming soon!”, might not be implemented.

On Arch Linux, using the quectel lpad software, I use this command:

sudo ./quectel_lpad -D 2 -A <activation_code>

And it returns:

Quctel LPAd Version: 1.0.7
Log level : 2
########## Add profile ##########

Any help? How should I correctly add the profile with this firmware and behavior?

Thanks in advantage!

Dear @andgarriv
Please confirm that follow the steps in application note.
Is your eSIM support LPA? Or M2M？

From your error, it seems the download profile was failed, please confirm the server address.

ST4SIM200M may not support LPA and that is the cause of my problems. :upside_down_face:

Hi,

I have a similar problem with RM520n-GL Rev. RM520NGLAAR01A08M4G_01.206.01.206. I’m using Infineon SGP.22 (consumer) eSIM’s. The Quectel LPDs send’s:

Any idea’s?

Dear @andreas.rupf
Do you enable LPA?
AT+QESIM=“lpa_enable”
AT+QESIM=“eid”

Dear silvia,

After the FW update of the RM520N-GL I did not repeat this setting. Now the query returns:
+QESIM: “eid”,89049032123451234512345678901235

Unfortunately I get another error:
[DEBUG] [QMIM] [qmi_manager//qmi_manager.c] [430] module works in QMI mode
[INFO ] [QMIM] [qmi_manager//qmi_manager.c] [478] Init QMI Client(0) Success

Dear @andreas.rupf
Is it possible to capture log for analysis?
If yes, I will share the tool to you. Windows or Linux?

Yes, it is possible to record a trace. I’m using Ubuntu 24.04 in a VM. Please send me the recording tool.
