       With some ESP-NETIF drivers in place, time to start digging into the #CoAP portion of this more. One of the questions I was mulling during the stream was if I would need to do device signaling on my own, with low level frame or UDP or if CoAP could handle this. Some reading on CoAP I learned it is supposed to accept broadcasts on 224.0.1.187. But updating the code to request on that address didn't work. Next up is to investigate how to get CoAP/#LwIP to listen on that broadcast address.

       holy heck! I got #CoAP over #LoRa working! I had expected more issues with packet management, waiting for TX to complete specifically but one again it's 'just worked'. Admittedly with only two devices in a tame environment but still super cool. In addition I found the 223.0.blah broad address wasn't going to work without additional work but turns out CoAP with #LwIP will respond to requests on, 255.255.255.255.
