r/meshcore

My wife and I are going to a 1 day music festival (in the UK) soon where there's likely to be no mobile reception, so we'll each have a T1000-E in case we lose each other.

The arena is mostly open so line of sight should be good - apart from 100,000 people!

Am I best to configure them:

1. In standard mode, relying on direct communication or a repeater (which is unlikely).
2. In off-grid repeat mode, benefiting from anyone else there doing the same, or direct communication if there isn't.

Or... is Meshtastic a better option in this scenario?

I've set up a companion and a repeater - both Heltec V3s - and they seem to be working OK.

They are 2 of the 4 on the north Kent coast in the photo.

Messages get sent and I get a 1 repeater notification (obviously, me) but there are no responses from anybody else at all.

I'm showing 297 contacts on the Meshcore app.

I also see what appears to be one half of a conversation - a response to a message but don't see the original message itself. Is this normal?

How can you tell if your message has been received? - sorry if this is a bit naive but I'm used to ham radio where we actually talk to each other :o)

Hi,

I bought some of the Seeed Xiao nrf + wio board combos and in the data sheet it says 22dBm max power.

I live close to cell towers and need to use filters, as far as my experience shows so far with heltec devices. For the heltecs I bought expensive saw filters from a shop in Germany which support up to 28dB and have low loss.

But the Seeed nrf chips I bought for cheap optimized repeaters placed in the countryside. So no large investment wanted. I discovered cheap saw filters on AliExpress and bought some. They say max 20dB. Do any of you have experience with them? I'm sure some of you have already tested them.

Do I need to limit the repeater tx to 20 to not fry them? I know 22 is a lot more energy in mW than 20, but maybe they can manage that? I don't want to put my repeaters in hard to reach places and have them break down after 6 weeks.

I got a cheap panel from TEMU and it only makes 3w. So my RAK repeater is loosing a little ground each day. It seems 5w is the minimum. Hope this benefits someone.

Such mesh, much range
Packets whisper through the hills
Wow, still no ACK

I am about to make a 8 km hike with 1.4 km elevation gain. Hoping to reach out to nodes 64 km away with line of sight. Should I put a 1W node in the enclosure? I already have a few regular RAK 4631 I could throw in but I want to make the most out of the hike.

I was going to go with a 1W RAK but if anyone else knows a better 1W node let me know.

Just ordered a meshcore lilygo T-deck plus. First ever mesh device and looking forward to seeing what it's all about.

If I get hooked (inevitable) then looking on building a 1W repeater for the house. also a 1w repeater that I can move and travel with both sola. Seen the new high power board and need a new project.

Any advice for the lilygo and build welcome. Uk based also so got the 868mhz.

Just wanted to check in and see what's going on here.

I have Meshtastic and Meshcore running. Strangely enough, Meshtastic is much more reliable, even though you usually read the opposite.

Not much is happening on my end - I keep getting messages, but it seems like hardly anyone ever hears me.

The nearest repeaters are barely helping - all the traffic goes through one that's 50 km away.

The conversations are always very choppy.

MeshCore

Everything looks OK, but still nothing, not connecting to anyone.

This is probably a case of having it too low, and I want to work on that at a later date, I just want to see if it's functioning at all first.

Have got it up in a tree, about 7ft.

The repeater is on, I can log in to it.

If I send a message, there is one repeat.

Settings for Australia appear to be fine.

But nobody can see me, not showing up on anything but my own map on the meshcore app.

Hi all,

I have been on here and YouTube often trying to learn as much as possible about setting up my first mesh core system.
I have a wio tracker L1 pro and will be building a repeater with a heltec v4. I have a few questions regarding the heltec v4 build:

I plan on using a 10000mah battery connected directly to the v4 with a solar panel charger.
I’ve read that the v4 does not have a low voltage disconnect and that has the potential of damaging the battery. Is directly to the v4 the common method or is a charging management board recommended?
I believe I’ll want to use the lite sleep firmware as well, the one issue I’ve read is that the clock will not stay accurate due to sleep mode. Does anyone find this to be an issue? Once the repeater is setup, should I set the
l1 tracker to a companion? Any and all input is welcomed.

I am probably going to stick with meshcore because there are a lot more people in my area running it than meshtastic. However, I have been trying out both, and think I like meshtastic better. The UI feels much more useable and has more features (HAM mode, ATAK compatible, ?). I also like that you can still see your other nodes while connected to one of them. Not trying to be rhetorical, just curious, what does meshcore offer that is better than meshtastic?
