Hello Quectel Support,
I am using a Quectel RM520N-GL via PCIe on Windows 11 in a Lenovo ThinkPad P16s Gen 4 AMD.
Firmware: RM520NGLAAR03A03M4G.
PCIe, QMUX and UDE drivers are working correctly. The Quectel serial driver qcser.inf 30.0.0.7 is installed and contains the “Quectel UDE AT Port” definition, but no AT/COM port is currently enumerated.
Your “3.PCIE in Windows” documentation says that AT ports are hidden by default and recommends using QSwitchPortTool_x64_V1.0.9.7z and selecting ALL port.
Could you please send me the official QSwitchPortTool_x64_V1.0.9.7z, or the latest equivalent compatible with RM520N-GL PCIe on Windows 11?
Please send it via private message if the tool cannot be posted publicly.
Thank you.
