Em7455b issues with creating NEMA COM

i need to figure out why the NEMA com port no longer shows and how to fix this issue.

Hi @RSUDOL,

Please check that NMEA interface is configured on your module by AT command !USBCOMP as below:

AT!ENTERCND=<“key”>
AT!USBCOMP? (Response should have "nmea" value)

You can refer below picture:

If NMEA interface is not configured on your module, you must enable it.
You can refer more information for AT command !USBCOMP at page 56 in this document: AirPrime EM74xx-MC74xx AT Command Reference

Thanks,

What would you use to connect to the sirerra wireless unit.

Hi @RSUDOL,

Which connection do you want? Is the connection to send AT command?
If yes, can you go to Device Manager > Modems and check whether AT port exists in menu? You can refer below picture:

If you cannot see AT port as above picture, please re-install Windows driver for your module. You can get this driver at link: https://source.sierrawireless.com/resources/airprime/software/airprime-em_mc-series-windows-drivers-qmi-build-latest-release/#sthash.43GdCH5t.dpbs

Thanks,
