I need volunteers for a test. I’m hosting #nomadnet #reticulum page on my experimental micropython esp32s3 node. Could you connect with nomadnet capable browser (MeshChat would do fine) with a tcp interface to rn.varnatransport.com:4243 and see if you can load the page? On the page there’s a link with mp3 - easter egg message (2kb) 😁 The page is hosted on the esp32s3 itself (below). I’ll leave the node online for few hours to see if it’s stable with more than one link (me).

@circfruit wouldn't I need an address to connect to, i.e. a reticulum address instead of an IP address?

circfruit Mar 10

@cm I’ve set it to announce itself every 60 seconds, so it should appear in your announce list shortly after you connect.

christian mock Mar 10

@circfruit Yes, I can actually connect to it, and I see the page!

circfruit Mar 10

@cm can you check if you can click on the Message link at the bottom of the page and see the mp3 easter egg :) this file is downloaded directly off the microcontroller 😄

christian mock Mar 10

@circfruit I already downloaded that and listened to it... that's definitely nice, what code are you running on the ESP?

@cm I’ve made a micropython port of reticulum and LXMF, but I haven’t uploaded to the repo the last major changes - Direct link messaging. I’ll upload it shortly there. Here’s the repo: https://github.com/varna9000/micropython-reticulum

@circfruit this is amazing work, I've always liked #Reticulum but was limited that it needed a fairly substantial system to work. Looking forward to having a go with it

@circfruit just to say I've got your code running on an ESP32-C6 (a dfrobot beetle dev board). Wasn't difficult and seems to be running pretty well, seeing a lot of traffic. I've got it connecting to my local node on my WiFi network.

I'm interested in using it for a sensor network backbone.

circfruit 1d ago

@smallsolar cool! Shouldn’t be too difficult to add more sensors. There’s lot of drivers for micropython. I just added for particle sensor sds011.

smallsolar 1d ago

@circfruit I've come across a memory issue with the C6 - I've opened a GitHub issue, currently browsing the code to understand the issue.

circfruit 1d ago

@smallsolar I’ll look into it. How much memory you got?

smallsolar 1d ago

@circfruit ESP32-C6 board I have has a 4mb of flash, 512kb of SRAM but doesn't have PSRAM and is RISC-V - didn't know if the lack of PSRAM made a difference

@smallsolar just replied to you in the repo, but you just need board with more ram. Micropython itself consumes more than half of the your board’s ram. I could try to cross-compile the drivers into the firmware, which potentially could reduce ram consumption.

smallsolar 1d ago

@circfruit I can easily get an alternative board, so cheap these days.

It does work fine for about 5 minutes, I added `self.online = False` to the exception that prints the poll error in `tcp.py` and that seems to force it to try and reconnect for a period of time and it gets back working again quicker then just waiting and have it erroring

circfruit 1d ago

@smallsolar honestly, buying a board with more ram would be the easiest solution. There’s a c++ microeticulum firmware but it’s not complete. If they complete it, you should be able to use it on more memory constrained boards.

smallsolar 1d ago

@circfruit ordered 🙂

@smallsolar good choice! As you said, they are cheap enough not to bother with the others. I got one working since yesterday with sds011 and bme280 sensors, serving a nomad page with the (almost) live data. Current uptime: 14h 8m 41s, so looking good 😊 Yesterday I’ve uploaded the latest changes to the repo btw (driver for sds011). You can check it out if you connect to TCP rn.varnatransport.com:4243

@circfruit (continuing the sensor thought process) I was having a think about efficient uses of reticulum as a sensor network, for remote nodes with aggressive power saving I was thinking that the best option would be for them to wake up, announce and then send a lxmf message to a known destination before going back to sleep, reticulum would then route the packet via whatever route is possible.

While reticulum adds overhead overall for a sensor network I think the built in routing and multi-interface options makes it worthwhile - particularly with these fairly high powered MCUs these days.

circfruit 1d ago

@smallsolar yes, this was my idea too. Or perhaps hook a solar with few batteries and leave it running. I’m going to test such node in transport mode so it acts as router on a tree in the fields.

@gerg great! Thanks

@gerg thanks for testing!
