https://espressif-docs.readthedocs-hosted.com/projects/espressif-esp-drone/en/latest/communication.html , https://github.com/espressif/esp-idf/ ... identify server and client not by ip address but by did:key and resolve ip address from this if needed for connection ? (how do I structure the web socket server and client ... do I switch my present configuration and make my Node.js server the websocket client and the ESP32 the server?)

WiFi: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/wifi.html (runs below websockets I think, I don't think you can design your own wifi protocol, nor should you ... read it though....and understand what level didcomm lies on in comparison to websockets, http, tcp/ip ... I think you can send raw packets somehow...hmm... https://gist.github.com/mic159/f546974d642f4189958423fbefe27902)

https://docs.espressif.com/projects/esp-idf/en/v4.3-beta2/esp32/api-guides/wifi.html#side-effects-to-avoid-in-different-scenarios
"Theoretically, if we do not consider the side-effects the API imposes on the Wi-Fi driver or other stations/APs, we can send a raw 802.11 packet over the air, with any destination MAC, any source MAC, any BSSID, or any other type of packet. However,robust/useful applications should avoid such side-effects. The table below provides some tips/recommendations on how to avoid the side-effects of esp_wifi_80211_tx() in different scenarios."

Do it over....sockets ... didcomm over a mesh network???

Do it with ESP-NOW?

Don't confuses hyperledger indy with hyperledger aries. The former has to do with V.C.

The messages should be done in CBOR, especially for lightweight protocols like LoRa. https://cbor.io/

or try DIoTDComm from "A low-overhead approach for self-sovereign identity in IoT" from Geovane Fedrecheski et al.
