Latest RM520N-GL firmware

Do you mean other commands will be activated when esim is added to RM520N?
but when I tried to add esim with LPAD, if failed with below logs:
[DEBUG] [QMIM] [qmi_manager//qmi_manager.c] [433] module works in QMI mode

my 520n provider dont know how to solve it, He asked me to call quectel offical help.

Dear @bsd
I have sent it to your email, please check.

Please contact with your provider firstly next time, they have access to get the latest firmware.
Thanks for your understanding.

Dear @TrashJager
RM520NGLAPR01A03M4G is too old. It can’t upgrade to RM520NGLAA.

Is it a engineer sample?

Dear @bhenp
Please check the version of LPAD and firmware version.

I will send the eSIM application note to you via Message, please check.

my 520ngl firmware version: RM520NGLAAR03A04M4G_01.203.01.203
LPAD version: quectel_lpad_v1.0.2
thanks a lot!

It shouldn’t be an ES. To confirm you mentioned the AA version. I have the AP pcie only version. Is correct?

Dear @bhenp
Did you follow the steps to activate eSIM?

Dear @TrashJager
For MP samples, there are the same firmware for AA and AP.

I am not sure why you have so old sample and firmware on your side.

I tried step by step , but failed.

does my quectel_lpad software version be ok?

To confirm you mean the firmware is the same between the two models on MP samples? With Qflash I get DL error on the firmware I can find online for the GLAA.

The only ones that could flash are from Lenovo and seem to be made for the GLAP. However the Lenovo firmware is very cut down and unusable outside of Windows. Could you send me a version that should work with my sample? Thanks!

Dear @bhenp
Please check the information below:

  1. Check if the qmiwwan driver is loading properly;
  2. At+qesim=“lpa_enable” Query the configuration, expected to be 1;
  3. Is eSIM properly recognized

Dear @TrashJager
As mentioned before, youe current firmware is too old, there are some limitations during upgrade with AA version.

If want to upgrade your device to AA version, it has some risks due to we don’t upgrade between AP and AA firmware.
If accept the risk, I can share to you.

Thanks for your concern. I accept the risk.

Thanks for your infomation.

  1. The qmiwwan driver works well with a physical sim card;
  2. At+qesim=“lpa_enable” configuration is always 1, even rebooted;
  3. What about ” eSIM properly recognized“ ? Could you show me more infomation, please? such as steps how to check

Dear @bhenp
Please use this to query:
AT+QESIM=“eid”

Dear @TrashJager
I will share to your email, please check.

If upgrade fail, the module will be stuck. Please note this.

Thanks for sending the files. The QCN backup fails with Could not Communicate in Diagnostic Mode. I was able to successfully backup the CEFS. Do you know a workaround or solution to this?
