EC21-E debugging AT commands

IoT Modules LTE Standard Module

Hello!

I have a EC21-E module.
I’m connected through the debug UART of the module to debug my application.

Is there a fast way to supply AT commands from within the quecopen system?
If so, which /dev/tty interface should I use?

I’ve seen other people online using an “at_com” binary but my firmware/quecopen SDK (EC21EFAR06A05M4G_OCPU_20.001.20.001_SDK) doesnt have it.
It’s a little bit outdated, maybe it’s in a newer version?

You can try the /dev/smd7 or /dev/smd8 for AT command.

Thanks! In the end I’ve used the following command:

atinout cmds.at /dev/smd9 -
