EM7565 Windows 10 Connects but No Data

IoT Modules MC/EM Series
1

Alright…

Trying to get an EM7565 card to work with Windows 10… Suspect I am missing something…

Laptop 1… Install card, laptop no longer turns on… Would prefer to use this computer, any ideas why laptop will not power up with the card installed? (Latitude 5400, not a BIOS whitelist issue)

Laptop 2… Computer boots, after installing drivers, Turn ‘Flight-Mode’ on/off, then can turn Mobile on… Shows signal, connects, shows expected IP address, but doesn’t work. No incoming traffic? GNSS doesn’t work either… Connecting to the NEMA port shows the feed, but as no signal.

Any suggestions?

for laptop 2, what is the return of the followings in modem port?

how about changing it to use MBIM?

at!entercnd="A710"
AT!usbcomp=1,3,100D
AT!reset

Thank you, that seems to have fixed it, don’t need to toggle Flight Mode anymore either…

Is there a trick to make sure that it sticks?

Previous cards used USBCOMP=8 when installing the driver… Is there an updated command that should be used?

6

Other user also uses USBCOMP=8 to make sure modem port is enumerated:

7

That worked on the 74xx and 73xx cards, same with the USBCOMP= AT command… Does that still work when installing the 7565 cards? I know I tried it a few times, but I tried many things…

8

didn’t you already prove that works?

9

No…

./GenericDriverSetup_5087.exe USBCOMP=8

Definitely doesn’t work, for the EM7565 anyways… It did/does for the 735x and 745x cards though.

Will changing it to,

./GenericDriverSetup_5087.exe USBCOMP=1,3,100D

work as GenericDriverSetup_5087.exe USBCOMP=8 did for the older cards?

Seems not using same parameter in usbcomp, you can double check

Btw, why don’t you just enter the AT!usbcomp command manually for your em7565?

AT!GPSAUTOSTART=1,1,255,4294967280,1

Fixed the GNSS not working.
