Modules Compatibility with GL-M2 Development Board

Technical Support for Routers 4G LTE, 5G NR, USB modems

Hello. Is M2 5G Development Board compatible with 4g LTE-A modules such as Quectel EM060k-GL? And also is it compatible with other routers with OpenWRT OS?

If my router doesn’t have USB port and only has LAN/WAN ports how can I connect this M2 Dev board to it and connect to the LTE internet?

I don’t know much about this, I don’t think GL has implemented compatibility with other devices and modules, but we can make the M2 compatible with other devices by tweaking the drivers ourselves?

The M2 is just a USB converter. So it doesn’t need a special drive.

M2 does not have this function.

So does this converter works with LTE-A Category 6 modules such as Quectel EM060K-GL or only works with 5g modules? Or this compatibility depend on the hardware and software of the host router?

Yes,this compatibility depend on the hardware and software of the host router.

Hi,
I have purchased the gl-m2 board. I am trying to use a EM9191 5G Module on it.

Is the gl-m2 board suited for the EM9191 ?

I am not getting any USB detection after 60sec, event after pressing the reset.
I am trying to use the USB 3.0 interface, perhaps a strap is missing for the EM9191 and PCIe is selected instead.

Any feedback would be greatly appreciated.

Can you set your module to usb mode?

Hi,

I was able to set USB mode with additional strap to M.2 Pin 20 and 22.

  • 20 : PCIe Disable needs a 1.8V pull up
  • 22 : VBus Sense needs a 3.3V (up to 5.25) pull up

Not very easy to solder on the M.2 connector.

I have USB 3.0 data showing up. Need to look at the software needed.

Thanks.

I looked up AT+QCFG command and it is not listed as part of the AT command in the manual.

On the modem :

AT+QCFG
ERROR
AT+QCFG?
ERROR
AT+QCFG=?
ERROR

With the hardware straps, this works.
