Hi, I have several EM9190 working in PCIe Mode with the latest driver and even managed to include the GETAC based Virtual NMEA Port. However in PCIe Mode not AT Port or Modem Port tp send AT Commands shows up. The interesting thing is that during installation even the UDE Client pops up but then di…

This doesn’t work at all. It only creates a “Sierra Modem host interface” section in the device manager under that a Sierra Wireless EM9190 PCIe Device is listed. I was using the driver out of the microsoft update catalog, version Sierra Wireless Incorporated - System - 23.2.6371.8 in combination w…

that Windows driver is for USB actually Are you using a GETAC device? Have you checked with GETAC on this?

No, I use a genuine EM9190 with the GETAC driver which I modified to get the virtual NMEA Com Port which works perfectly fine. However I want access to the AT port to be able to use AT Commands like on any other modem For whatever reason, neither the GETAC driver nor the original Semtec/Sierra Dri…

[image] airmaxsc: PCIe driver for the EM9190 which installs USB AT Com Ports and the keeps the existing USB NMEA port. I don’t understand this how can PCIe driver install some USB port? BTW, if you want to use USB AT port or USB NMEA port, you need to check pin 20 and pin 22: […

Uhm…I struggle a bit to believe what you say?! The EM9190 can be run in USB Mode or in PCIe mode depending on the environment it is installed and the corresponding driver (USB or PCIe). USB Mode is usually used in USB adapters or dongles while PCIe mode is used when the module is directly installe…

what are the pin state of pin20 and pin 22 in your board? If you install the PCIe driver correctly, you should see the following: [image] Have you contacted the distributor to get the PCIe driver?

As for these PINs they have the usual Key B layout, so no Pin 20 raised for USB mode. I think I use a totally different driver than you do? Which is it that you use? Anyway I then would again need to find a way to integrate the NMEA port for GPS as shown on the bottom of this picture. [Sierrra …

Yes but the distributor is a member of AliExpress, a salesman. I must use PCIe because the module sits in my Laptop in a NVMe M.2 Key B Adapterboard with key B+M interface in the 2nd NVMe slot which works great. As NVMe only has PCIe lanes there is no way working with USB. Please tell me which dri…

you need to contact distributor to get the Windows PCIe driver or you can use linux platform with the PCIe/USB driver here: Mobile Broadband Package for Linux (SDK, Drivers, Documentation)

Have you contacted the distributor to get the PCIe driver?
Is that you must use PCIe interface instead of USB mode?

Actually your NMEA port is virtual, it is getting the QMI location message and display in the virtual NMEA port, you can see how it works in linux here:
