Re: Network Manager on Raspbian 2020-02-05

Question related to nm on rpi: I'm trying to set up a USB WWan LTE aircard (Netgear 330u Beam) and all of the tutorials I find for setting it up on a linux use network manager. It works just fine setting up a gsm connection with the AT&T apn (broadband) on Ubuntu but when I try to do the same thing ...

can't get Netgear 340u Beam on Raspbian

I've been trying for years to get some kind of wwan card working on a raspberry pi. I've tried the AT&T LTE dev kit (got it working but not where I need to use it - protocol not supported). I tried a sierra wireless hotspot - couldn't figure out the tethering. I tried a Sim7000a - couldn't get it to...

Are there such images available for the various raspbian updates? Or are your own ch...

OK, py2exe may not be able to create programs that will run on raspberry pi, but there's no reason it couldn't create exe files that would run on a windows machine. It just needs to cross compile to suit the target platform. Now that doesn't mean anyone has ported the code over, but creating an exe ...

They say that they have to use qemu for many components which means it would run very slow on arm.
