LGA DevKit + PLS83-W Module / AT Commands problem | Thales IoT Developer Community
June 18, 2021 - 1:56pm, 5373 views
Hi,
I am currently trying to set up QMI/RmNet on the PLS83-W module so following this tutorial (PLS63/83 QMI/RMNET Setup and Linux qmi_wwan / ModemManager Integration | Thales IoT Developer Community (thalesgroup.com) ). I first need to configure the module via GTKterm with AT commands.
Problem is, I want to send AT commands through the native USB port of the LGA Devkit but GTKTerm terminal doesn't detect any USB ports means I am unable to communicate with the module with AT commands.
On the other hand, when I send AT commands through ASC0 USB port (VCP USB), I am able to select an USB port and see the AT Terminal so I can send commands.
In short, I was wondering if there is a way to be able to send AT commands through native USB port via a terminal ?
Thank you in advance for your answer,
Best Regards

Hi,
I am not Bartłomiej,
but as your dmesg shows the qmi_wwan driver binds to the USB ACM interfaces which causes the side
effects observed.
This does not happen when using the official Linux kernel patches
