>retiqr
https://github.com/metrafonic/retiqr
I have spent the last couple of days putting together a way to connect to the reticulum
network in situations where the only way to access the internet is via some form of
internet kiosk. So no wifi, ethernet etc.
retiqr allows you to access the network by bridging a TCP connection via the kiosk
browser. Packets are received by your device by visually observing incomming packets
encoded as QR codes on the screen. These are decoded and sent to your local rns instance.
Packets are transmitted back via an emulated keyboard on an ESP32S3 connected to the
kiosk USB port (linked to us via BLE).
Typical throughput: ~3 kB/s down (QR), ~500 B/s up (HID). Enough for messaging and Nomad
Network.
Let me know what you think! Open to feature requests.
Also check out my [guide on running reticulum over
DNS](https://github.com/markqvist/Reticulum/discussions/1002) (captive portal situations
etc)

It would be awesome to have the camera part running on the ESP32 as well. Not sure if
it's fast enough to do the actual QR decoding in real-time, but at least it could just
forward to captured images to the host for QR decode there. Then again, QR decode is not
too expensive, if I remember correctly, so could probably be done. Then you'd have a
self-contained dongle that's easy to place in front of the screen, plugged into the USB
port, acting as a full bridge to Reticulum.

Thats a great idea! Initially my idea was to use components that people have at home. But
i realise now that most people dont have an esp32s3 at home haha, so might as well go for
one with a camera! That would be a super smooth setup! Could even try to make it
piggyback on the ble interface torlando created.

oh man I got COMPLETELY nerdsniped by this and went down a few paths haha, let me share:
Core idea: There's a WebHID API in browsers. If you look at caniuse
(https://caniuse.com/?search=webhid) it looks a little grim, but I thought, "Most Kiosks
in the wild are probably running Windows, and therefore very likely to be running either
Chrome or Edge, both of which are where support is quite good!". I figured if you can
get through via USB with the HID trick in the first place, then the same kiosk is likely
to allow the browser API too.
Three benefits: much higher bandwidth becomes possible, it's a bit more discrete (someone
looking over your shoulder wouldn't see a bunch of QR codes. Not a huge deal but just
something to note), and the consuming device doens't need a camera anymore either.
Now, because of conditional WebHID support, and quite frankly because the standard QR
mode is WAY cooler, the thought was just to provide this as an optional mode to
activate via the web page, especially since you need to approve the web page permission
dialog for the WebHID anyway.
Got that working on Chrome for my Linux laptop (Chromium from snap didn't play well, but
that's not really the target here). Couldn't help myself as I got into the optimziation
flow, and got to a point where it was delivering ~300 Kbps goodput, basically
bottlenecked by BLE instead.
I saw 300Kbps on a 1M PHY and figured "yeah that's probably near the reaosnable limit".
I was about to get that wrapped up and then report back here.... but another thought
popped into my head that I couldn't push out:
"Wait, if bluetooth is the bottleneck, couldn't we switch to running this as a WiFi AP?
Same 2.4 band, should work great. With any luck, the USB will become the new bottleneck".
esp32-s3 is full-speed USB which IIRC is like 10 Mbps PHY but practically probably
4-6Mbps, still a huge step function. Or, worst case, WebHID will have some througput
limit and that's our hard ceiling. Worth the test.
I'm assuming something key: In a situation where you'd be doing this anyway, your wifi is
probably not being used (if you had a valid AP to connect to with internet
connectivity, you'd just use that instead of doing all this). So it seems very well
aligned.
AFter sleeping on it, also realized, "maybe Wifi AP would be a really nice convenience
factor even in the standard QR mode. We could just connect to our own sovereign little
AP, which might make it even more accessible (no desktop BLE client, just a tcp
connection). Might be a nice bonus regardless of the fast mode stuff".
Alas, it was indeed WebHID as the hard ceiling, but WiFi AP mode can still get roughly
1.5x the goodput up to that ceiling, which is ~450Kbps
Gonna stop here for now or I'll end up losing weeks to this lmao, but this was such a fun
exploration! I'll be sending over a PR, probably later today. If this is just purely
antithetical to the project, by all means you can toss it all, no worries. But still
wanted to give you that option.
Similar AI Disclosure as you: I'm also a dev by trade, similar YoE, and also used AI
tooling throughout this.
PS: I could probably swing a lil dedicated server to run the backend side for the
community to tinker with too, if you want. Just let me know!
tl;dr: Two new modes. For the transport mode, standrd qr or fast. For the user-side
link, BLE or WiFi AP. ~300 Kbps goodput in fast + BLE, ~450 Kbps in fast + WiFiAP.
Preparing PR and expect to have it submitted at some point today. Screenshot of using it

Holy cow I'm happy with how this has come along (just couldn't help myself, had to add a little more). I have some more to share which I think everyone here will really like! But just to bury the lede for a moment, I also want to make sure image uploads work correctly here real fast before I write up the rest. So to tease it a bit as well as test:

Alright! so as you can see, the web page allows you to configure the dongle as well. You
can flip between bluetooth and wifi, and on wifi set the ssid and password to your
choosing. (Note right now this is still designed for single-session links; I'm noting
that in the PR for high value future work to make it multi-client, so everyone in the
area can benefit if they know the creds!).
First up, showing that I see that valid hotspot on my phone, there it is! 'flybywifi'
according to my settings on the web page.
And showing/proving it's not a real wifi connection, no internet. (Also note if any of
you do this, make sure to check the box and say yes; won't work until you do).
With that all set up, I opened up the fantastic Columba app and added a TCP client as
normal
The host and port are still hard-set for now, to these values
Here you can see it's active, and it's the only interface active
First moment of truth... before /after hitting announce:
There it is! Data's flowing from my phone!
(Will continue; trying to keep these messages broken up in case too many image uploads
cause issues)
