I am trying to use my EM9291 as a dual sim with one slot as an eSIM. I am trying to send apdu messages with an lpac to save the profile onboard but it’s not working. I am using qmicli version 1.37 and modem firmware version 2.17
I also saw in the AT command reference document that the latest FW is 3.04 but on the sources page it only goes to 2.17.
Any advice? @jyijyi
FW 3.04 probably is referring to em91 module
So is eSIM supported?
I had trouble with LPA but I can get slot 2 as an eUICC - also I am using Ubuntu 20.04
what are the return of the following?

The 3.04 firmware is there under the PTCRB heading.
FYI Rel.8 includes modifications to the internal LPA meaning you will be able to communicate via LPAd such as LPAC. Rel.8 is 03.04 FW which is on the source.
@blackbow7 got it, I was using the 2.17 firmware under Generic - I will use the correct one and share results
**I am still having issues, these are the outputs to those commands:

I do not have windows on this device, I am forced to exclusively use Linux
you might need to contact distributor to get an application note “2174369 Thales LPA SDK r1.pdf” on this eSIM implementation
This document describes how to use Thales’ Linux host-based LPA SDK to manage eSIM profiles over the EM9 module from Linux host machine.
