I do it through AT commands, but I am on an embedded device
It looks like you are using a linux box. I believe the Nova creates a PPP connection that basically behaves like a network port. So if you don’t have wifi / ethernet plugged in to your linux box, all network traffic will go through the Nova. In that case you can just use
curl or or a python script or something to make an http request just like you would over wifi/ethernet.
You should only have to use the Hologram SDK to setup the nova and if you want to communicate via the hologram cloud.
**The warning for accidental stickershock is that all network traffic goes through the nova just like wifi That means if you download updates transfer files / etc. you pay cellular data pricing. Updating python libraries could cost you 5$, etc. I would be careful when playing around with the linux box with the Nova plugged in and enabled.
