[Ribbit-Developers] Packet format

[W4CKX]

Hello Josh,

Thank you for reaching out

The message header metadata is being defined. It's not finalized and won't
be until we get extensive real world testing.

In an emergency, the situation would be cellular denied with limited to no
connectivity. So wouldn't MQTT be reliant on having an Internet network
running?
Remember that the nodes (user radios) are loosely connected on ad-hoc
transmissions.

I hear your feedback on PWA apps.
I am curious to learn:
Does a PWA app allow access to the phone audio in/out microphones,
speakers, line mic in, line out?
And this reliably across phone makes and models?
