It's still got some issues, but looks like UDP/IP works for the most part. I've done a couple #CoAP requests, so that's cool.
There's a bit of into in the repo but this will need more detail and a larger writeup of the whole project(s), covering
#ESP32 #NetIF <> #ESPNow,
#LwIP over ESPNow
#Linux #TUNTAP <> #ESPNow
And that's all just been groundwork for what I really want to do (recap: CoAP like serverless #MQTT)
