No APDU driver found when I compiled a LPAC using AT cmd

[ofilmt]

I tried recompiling the code using the AT interface, but after using it and sending the command lpac driver list, the response was "No APDU driver found." My system is Windows 11, and I'm using a Samsung smartphone. I have installed a serial port tool on my computer, and when sending AT commands through this tool, the device returns results normally. Could the issue be with my code compilation? Could you tell me how to compile the code using AT commands? I have already read the documentation, but I'm not sure if I missed anything. Thank you very much.

oh, I use Clion to compile the lpac.

I compiled on Linux too, I'm seeing the same issue when I try LPAC_APDU=at.
There's been a redesign of the codebase for the last 2 months. Might have to ask the devs regarding this.

We don't compile AT backend of APDU by default. Have you added LPAC_WITH_APDU_AT=ON to CMake arguments?

[Josef-Ouano]

Can confirm this works.
I added above LPAC_WITH_APDU_AT=ON to cmake arguments.

Tested using Quectel RM520N-GL on Ubuntu 24.04.2

Configure to esim slot:
sudo mmcli -m any --set-primary-sim-slot=2

Build:
cmake -B build -DLPAC_WITH_APDU_AT=ON
cmake --build build

Test run - profile list:
sudo LPAC_APDU=at LPAC_APDU_AT_DEVICE=/dev/wwan0at0 ./build/src/lpac profile list
