Frustrated... Cellular Advice...

[mjohnsonsa]

Is it possible to use a Huawei 3G Cellular modem with the NanoPi NEO2? I have been messing with it for several weeks on and off using different images and cannot get it to work.

When you plug it in what does lsusb tell you?

Are you performed a modeswitch as it has probably said it is a storage device not a cellular modem.

Which model, I have been playing with a E3531

I went through setting up so it recognized it as a modem using usb modeswitch and it does now recognize it. It also shows the WWAN interface. The problem is it just does not connect, as soon as you plug it in in should go to a solid blue light but it just does a green blinking light. I put the modem in the laptop and without setting up any drivers or software the light goes blue and I can see traffic on the cellular dashboard. I also get a solid blue light and can pass traffic when using it on my Raspberry Pi. I am wondering if the Kernel or something on the NanoPi is missing something that the Rpi has?

I am using a Huawei MS2131 and have tried every OS that the nano pi has available for download. Any advice?

i then ran 'ifconfig -a' and it shows the wwan0 interface so that is good:

When you have it working properly on another platform what does ifconfig give you. I wanted a MS2131 to use on Hologram Cloud, but I choked on the price. Bought the E3531. With that unit one needs to do a modeswitch. Evidently that is not required with your MS2131.

There is a tutorial at hologram.io using the MS2131 on the RaspberryPI, maybe there are some clues in there although you have it working on the Pi.

I found that I needed to plug my E3531 in first and then do modeswitch. To hotplug it you may have to play with some init.d file or udev rule or ?

Maybe you need to apt-get some tool, sorry I don't know.
