Hello #MeshCore

Lilygo T-Beam as Companion and Xiao ESP32S3 as my Room Server and Repeater.

There are not any nodes nearby yet - but maybe it will change after some time...

After not having much luck with Meshcore on my initial Seeed S3 WIO boards, I ordered a pair of Heltec V3 boards to test instead, which arrived yesterday.

I spent a chunk of this evening trying to get those two to talk to each other with no luck, and then I pulled out the spare Seeed board to use as a room server, and was still getting nothing. I do not understand why. I tried lowering the tx power as well, in case they were screaming at each other here on my desk, and tried moving one to the other end of the house, but it was still just silence. Nothing in the packet log (yes I started logging).

Then I tried reflashing the Seeed with companion firmware (which didn't work last week), and hey presto everything started seeing each other?!
Which was especially weird seeing as I hadn't even switched the frequency on the Seeed at that point, but everything kept working even after I'd set it correctly. So either nothing is actually using the configured frequency, or things are so slow and wide that it got picked up a few channels over. I'm leaning towards the latter, but I don't have an SDR to see what it actually looks like.

Dammit, now I want to add an SDR to my kit too!

Aaanyway. Meshcore now working for me, and there's still nobody else visible to talk to. I'll see if I can get the room server/repeater up high at some point and see if anything comes in view.

#meshtastic #meshcore

Bin in #Berlin und habe sehe viele #meshtastic Nodes. Gut, wenn nicht hier, wo dann...
Wer nutzt von Euch auch #meshtastic oder #meshcore ?

Ok #meshtastic and #meshcore people. Here's the results of todays testing with meshcore. I was able to walk all around my neighborhood and talk with my wife at home. I got in the car and could talk with her almost all the way at victory park. There's a repeater on Mt Wilson that makes this possible, also a repeater over near Lake and Woodbury. So with those together, the region is pretty big where I can talk. The choice to make only certain nodes repeaters is probably very smart and Mt wilson

MeshCore is a lightweight alternative to Meshtastic LoRa-based off-grid messaging - CNX Software

｢ While Meshtastic is by far the most popular off-grid messaging solution relying on LoRa radios, MeshCore offers an alternative as a lightweight C++ library and firmware designed for multi-hop packet routing and made for developers who want to create resilient, decentralized communication networks that work without the internet ｣

ok, well, flashed the Keltec v3 to #Meshcore, no problemo. But on my #grapheneos phone I can't get the meshcore app without using Aurora Store to grab it from Google Play. So did that, and then paired the device with my phone, but the app doesn't detect the device so I'm stuck with just no way to talk to it.

Well despite the lack of nodes in the area, I'm trying out #meshcore

Hello @why2025camp and all lifeforms to be interested,

I just saw that there will be some mesh stack be included in the #Badge

Is it compatible to #meshtastic or #meshcore or do you want to implement something special for the massive mesh to be unfolding on the Campsite?

Can you already give us a little glimpse?

Will there be talks about mesh use and limitations?

And can we flash it to connect to something common after the end() of the camp?

I'm so excited..
See You all @ #why2025

It seems #meshcore is a direct message first protocol, with group messages flooding like #meshtastic but the client nodes never flooding. There are two other roles with separate firmware. Repeater, and Chatroom. A chatroom, which can also repeat, stores messages for people who are offline. So there are synchronous and asynchronous messages.

Thinking that I'll flash my two nodes as mesh core tomorrow and see who's around.

really interesting to read @nullagent thread on LORA/ #meshtastic vs his preferred #meshcore. I'm also kinda surprised meshtastic uses the MAC as the identity, and if meshcore uses an encryption key that is really a huge improvement (decouples identity from radio). anyway I'll check out what's up on meshcore down here in LA.

Damn.. I need to block Aliexpress for me most probably.. too much orders for different things #meshtastic #meshcore

do any fedi creatures know how to turn old wifi routers into nodes for meshtastic/meshcore/lorawan/&c and how to best upgrade routers to have a larger range?

(this isn't about if we should, but if we can; also modifying hardware is always an option to add new chips or modules)
