MicrosoftPlease share your experience with tethered cellular
The HL2 powers up the ZTE and sees it plugged in, but does not get internet.
Will keep searching for "RNDIS" compatible 4G/5G dongle and post if I find any.
We've got the Telit FN980 (5G) running with hololens now.
FN980 supports RNDIS driver.
You have to configure the RNDIS Mode only initialy with AT Commands over any computer.
Enable RNDIS USB Mode:
- Check Current Mode: AT#USBCFG?
- Enable RNDIS Mode: AT#USBCFG=1
Here ist a List with possible Modes:
0: RNDIS + DIAG + ADB + NMEA + MODEM + MODEM + AUX
1: DIAG + ADB + RmNet + NMEA + MODEM + MODEM + AUX
2: DIAG + ADB + MBIM +| NMEA + MODEM + MODEM + AUX
3: DIAG + ADB + ECM + NMEA + MODEM + MODEM + AUX
Now attach FN980 to hololens and it should appear as Ethernet Adapter.
For auto connection to cellular networks the Autoconn feature of FN980 can be enabled after an APN was configured.
Enable Autoconn:
AT#ICMAUTOCONN=<apn-number>,<1: enable, 0:disable>
Example:
AT#ICMAUTOCONN=1,1
There is unhappily a problem with the power supply over usb. While transfering at high data rates (mainly upload), the power supply over Hololens USB-C Port is not enough. Transfering small data on low data rates is working without any additional power supply.
Dear Dan,
I found Telit FN980 only with M.2 port from factory.
Could you please tell more detail about which adaptor is used from M.2 to USB-C?
Would be great, you would share some documentations of the whole connection process?
Best Regards,
Guang
I've had some good luck with the MU201 adapter from TechShip.

Thank you very much! I will try this one.
- jbienzWow, very detailed response dan1-m. Thank you so much for sharing. Have you found a way to provide additional power if needed? I'm aware of USB pigtales that split power, but that's usually for charging the host device while using another.
