I’ve been using the Nova in the recommended way: Linux, PPP, TCP/IP (and even MQTT) for some time. While this works quite well, it uses more bandwidth that I had hoped for.
For future applications, I think I might try just using Datagrams, which add some overhead, but far less than TCP (albeit with loss of reliability), thus keeping to a low-bandwidth profile. Of course it is possible in Linux to effectively turn off TCP (say, by using firewall rules), I’m not sure if this is compatible with PPP.
The other idea is just to directly talk to the U-Blox modem. For instance, I see here
there are commands to send and receive UDP packets.
Does Hologram or members of the community have a how-to on doing this?
