Today two Heltec V3 boards [1] arrived and I put the first one in its nice looking case that I printed yesterday (model used: https://www.printables.com/model/936437-heltec-lora-32-v3-ht-slimpro-cases-by-alley-cat). Flashed the #meshtastic firmware on it and done. Connected to the other node, first message sent. Nice Will go out for a walk later to see what range I can get.

Ah, why not. Took me just 3 minutes. Second Heltec board joined the mesh and has a nice case too So now I have a 3 node LoRa mesh at home Tomorrow the 2000 mAh battery packs arrive, making the nodes mobile

@jwildeboer I'm totally not looking into the hardware for this right now...
Which modules did you get? 868 MHz or 915 MHz? Is the distinction important in Germany?

@blindcoder Must be 433 or 868 MHz for Europe, AFAICS. See https://www.thethingsnetwork.org/docs/lorawan/frequencies-by-country/ and https://meshtastic.org/docs/configuration/radio/lora/
433 is not used that often. 868 MHz is far more popular.

(I must admit that putting new experiments in nice looking cases that I can print myself on my 3D printer elevates the fun to experiment to a whole new level

And I already start to see more meshtastic nodes that aren't mine Nice! Time for that walk outside ...

Well. Walking around with my T-Deck is a disappointment. It needs a better antenna (which is on its way, should arrive tomorrow). The included sticker antenna just isn't doing enough. It sees no nodes out here. Bummer.

Slowly understanding the meshtastic mesh. Seems that naming your node "Meshtastic <last 2 bytes of BLE MAC address>" is the norm. So I renamed my 3 nodes to "Meshtastic e69c", "Meshtastic e99c" and "Meshtastic 1edc". And I am seeing a few more nodes directly and via hops (meaning that I go through a nearby node that forwards to more nodes out of direct reach). Nice!

Tomorrow I should receive two GPS modules that I can connect to my T-Decks (one I already have, a second one will arrive soon, I hope), allowing me to also collect positioning data.

And entering the world of antenna design for LoRa reminds me of high-end audio madness with argon filled coax cables for speakers But I ordered some antennas that supposedly are really good for 868 MHz transmissions

@jwildeboer details please! I tried to get into lora a few years ago but everything was a bit raw and new.

@hughsie Itβs so much better nowadays. Meshtastic is doing a lot of things very right, hardware is easy and cheap to get. But still a lot to be done to make it truly usable for the masses.

@hughsie I will do a blog series on my experiences and insights soon. Iβm still in the experimental phase right now.

@jwildeboer apparently you can make a decent dipole antenna just by cutting wire to the right length! I've had good luck with quarter-wave dipoles myself.
Sadly the Meshtastic software, on the other hand, has been really bad for me: I can't reliably tell when a node was seen last, and I have never seen a traceroute work

@zack I'm on the newest 2.5.1 Alpha and I see reliable "last heard" numbers.

Could you elaborate on decentralised identity ownership? Can that work without a trusted third party?
I'm looking into #spiffe now:
https://github.com/spiffe/spiffe/blob/main/standards/SPIFFE.md
That needs TCP/IP for mTLS, so I wonder if it could ever fit on a Meshtastic network... -

@KingmaYpe Oh, I could. But it would be a giant thread Not today β¦
