Birectional Communication between Heltec CubeCell and Heltec LoRA ESP32 (V2)

 Actually, this was a huge step: https://www.youtube.com/watch?v=3XOYRV0kSuo  to get something like described at the end of this call (https://www.youtube.com/watch?v=Z8Wf7Srsg5U) to work. I think the next step would be to try to get this to work. https://simplerpc.readthedocs.io/en/latest/index.html . Ultimately, it needs to use Ceramic's EIP-2844 interface with the HTTP API as well. I have not done a lot of worked with RPC before,
but ultimately it seems to be a way to expose a function as if it were local. The Heltec CubeCell needs some sort of bytes to trigger execution of a signing function, and the Node.js server speaking with a Ceramic node needs some sort of bytes (if needed) from the Heltec ESP32.
