morgans random stream of hack.

On this installment, 28/12/23, I will be working on #CoAP over #ESPNow.

Goals

esp-netif-now component
UDP device discovery
CoAP serivce/resource discovery
CoAP data peristance
Serverless MQTT
- Configuration

esp-netif-now

ESP-Now is a broadcast over WiFi management frames protocol.
By default in the ESP-IDF it does not get an LwIP interface. For the first
part of this stream I will rework my proof of concept code to write a
proper ESP-NETIF driver to bind ESP-Now to LwIP. The proof-of-concept already
works and writing a proper driver should be fairly straight forward.

CoAP

With the LwIP interface brought up automatic CoAP service and resource discovery
can be run. This will reach out to unknown devices and see if they have services
compatible with theirs, ie; a button looking for a switch.

This data should be persisted to assist with further configuration and future bringups.

Serverless MQTT

My vision for this draws heavily from Tasmota and it's use of MQTT endpoints for control
and status. CoAPs Observe functionality will be used a lot like MQTT server push.

Configuration

Unlike Tasmota I will forgo the web interface and all configuration should be accomplished
over CoAP. Resources being provided will start unconfigured and provide an output enpoint
that points to another devices input resource endpoint.
