So far I've been able to get just about everything running with Armbian but I just haven't got my head around routing a usb / mpci 4g modem. I clearly see it's a ttyACM0 device, I can see it's a USB connection in nmtui, ifconfig shows it as usb0 interface. I think the hardware is good and Armbian is talking to it fine.

 

Can someone point me to a tutorial somewhere that would turn the light on for a first time try at routing data from a cellular modem?

I'm using a clearfog pro but I also have an espressobin. The modem is a U-Blox MPCI-L201 and I imagine should work on either board.

 

I'm probably just not putting the right questions to uncle google ...

Thanks in advance

Check the data sheet...

You need to configure the modem itself correctly - it can be either a serial (over USB) or NDIS

 

The u-Blox stuff is pretty good

Hey thanks!!

 

I've torn through that, overwhelmed by 900+ pages in the AT command set manual as well as the examples ... I'm missing something stupid basic ... how do I get a terminal to do the at commands in the first place?? A good pointer would be awesome.

 

I'm assuming /dev/ttyACM0 with a terminal program? [screen / minicom etc]

 

Once it clicks I'm sure I'll be off and running ;]

I'm not sure about this. i'm just guessing.
Did you try Putty? There serial connection. Serial name : /dev/ttyACM0

It looks like you need a serial connection, but I'm not an expert (in nothing)

OK this gives me somewhere to start thanks. More questions come about but now I can ask unkle G ;]

 

Using the AT command set I should be able to edit one of the .sh files for the ublox. 

 

One thing I see in the data sheet is that part numbers ending in 00 don't support https ... this may be a show stopper for the most part. Gotta love those asterisks.

BTW on the clearfog download page it shows tested hardware Huawei ME909s - can someone point me to the setting for that one? I imagine almost everything but the vendor id's will be close enough to get started with.

 

Looks like I need to

establish a consistent interface name

configure the modem

set the interface

set the route to the other ports

 

Couple days more reading ;]

That's plug and play. Type armbian-config and if it is plugged you will have "Enabled/disable LTE"

@Stanislav Sinyagin is the man behind this and if he is around he can tell you more.
