The meshtastic protocol is limited to 230 characters to send and receive a message. I also made some test at longfast and it's working good. A small page take around 30 to 120 secondes without optimisation.

@Cotteux - that is SO COOL. Do you have the code uploaded anywhere (github, etc)? 3.5kbps isn't much, but again as a proof of concept that's excellent. A 200 character message size sounds (to me) like a pretty large "packet" of information. How resistant are each of these messages/packets to data loss along the way? Any updates since you've last tried? I'd love to see a video or something of how it worked.
@norayr - Thank you for the generous remembering of what LoRa/meshtastic does. fwiw, I was wondering whether such a physical layer could be built/written on top of those radios. The OSI lists seven "layers," on which the internet is built. I'm wondering if a mesh of LoRa radios can be made to replace the bottom two (maybe three) layers. If each of the devices can mesh by: 'serving' data to reqestors, 'locating' (data-request-wise) specific devices, or 'relaying' requests/responses to devices they can't find, then couldn't that become something like IP addresses?
From there, existing code could be plugged in to make layesr 4-7 work. Because LoRa is inherently slower (I was assuming 56.6k equivalent, though it looks like that's optimistic), the web that would run on that hardware/mesh/layers would have to be slower. That's not a bad thing. You'd connect to the capsules that were physically closer to you a lot faster than the stuff far away.
@olav - reticulum.network looks really interesting, thank you! From what I can tell, it's a chat/comms application for the sort of mesh networks I was thinking of. Perhaps their model is a bit more realistic in that it doesn't rely on only one kind of radio. I was hoping to host/serve smol capsules over that same kind of mesh.
@fab - wow that's unfortunate. 1% really won't work for this application. :/
@requiem - This is good to know. I'd not heard of ESP's, and I didn't realize antennae were so cheap. Out of curiousity, what kind of speeds are you getting on average with your LoRa devices?
I feel like "Gemini" (by Gemini I really mean the set of smolweb protocols which are aligned to Gemini) needs a sort of "reverse mail" mode, where servers co-operate to fetch data which might be available intermittently. Once that's the case, I think LoRa works well for that use case. Maybe something Gossip-related?
functionality through an occasional connection is a good goal. The only experience that I had with gossip was Scuttlebutt. Correct me if Scuttlebutt does not use Gossip. Scuttlebutt seemed very 'heavy'.
The code is not upload for the moment, the code is terrible and i need more testing. The protocol real speed in Longfast is 300 bps and MediumFast almost 1200 bps.
For the stability my protocol send the number of lines to received and I numbered all lines. If some lines is missed, the client ask these lines back to the server. Also the protocol can received Chat and Text page at the same time.
I send a link to a video showing a reception of the Gemini capsule spartan.mozz.us at LongFast .
Gemini over LoRaWAN? — I'm fascinated by the idea of running a smolweb over LoRaWAN. Imagine a decentralized network of FLOSS-hardware devices, solar-powered, each running a gemini capsule and a relay (HAM radio style) to transmit data on to other points on the LoRaWAN mesh network. It's not a fast way to communicate, but smolweb gemini doesn't need to be. If LoRaWAN can reach 56.6kbps, it'd feel like the days of dialup, but... decentralized, solar-powered, and resistant to censorship. Has...
