New Prototype
I just finished the second prototype, which is based on the Arduino MKR Zero platform (while remaining compatible with other boards). This prototype adds wifi capability, a smaller, almost pocket-sized physical form, and a much better UI. I have custom PCB on order, which should make creating more prototypes much easier, as well as making the prototypes smaller.
Next I will be building a distributed packet cache, where encrypted message packets are cached/stored on different devices throughout the cluster, to facilitate a more resilient cluster and reliable delivery. This will also significantly help as I create more elaborate meshing strategies.
