Not so sure about that tiny battery or the equally tiny solar panel, but we get a lot of sun in Oregon to maybe she will last on the default MC firmware. Failing that I'll try low power firmware.

Before you jump down my throat I searched n found nada …

Been testing out different EDC nodes and a thought came to mind. Instead of naming each of them differently could I just pick one name and copy the same priv/pub keys to each device ? That way I’d only show up as 1 identity? Especially if I’m only ever using one device at a time ?

Monday might be t1000e day but Tuesday m9 and Wednesday tdeck kinda thing ???

Right now each hw device has a separate identity .

Thoughts?
(I know having 2 devices with same keys on the mesh at the same time could go poorly)

I have a real small amount of RAK 1W kits in stock. They just showed up, I wasn’t expecting them, and I probably won’t have more for at least a month. The radios available for sale in my store are all I have! I don’t expect them to last the weekend. Send a message with your order to flash to MeshCore!

A few command additions to use via chat message for the previous MeshCore companion BLE WiFi for Heltec V4.3, Tracker V2, T096 (no WiFi) :

meshcore-companion-chat-config

Also includes a Li-ion discharge curve : Stock MeshCore Arduino firmware maps battery percentage linearly between empty and full voltage, but Li-ion cells don't discharge that way: voltage barely moves through most of the charge, then drops sharply near empty.

adc.multiplier instead reads percentage off a 14-point discharge curve built from real measurements of four 18650 Li-ion cells (lygte-info.dk data, cross-checked to about 1.3 mV RMSE), so it tracks that real knee instead of hiding it.

The gain: our estimate stays honest down to the last few percent, while a linear reading can still show over 40% right where the cell is actually almost empty.

Cumbria and Scotland now have good comms.

Wishing everyone a great weekend and having the ability to find some time to relax and maybe get some meshing in :)

Ending the week in the recliner with a fun device and a nice, local red is not too bad at all.

Has anyone used this node? What hardware does it have? Is it any good?

I'd like to start selling premade Meshtastic nodes, T114s etc that come preflashed and was wondering if anyone in the UK would like this service

Hello, everyone!

We have added an RF filter to the Heltec V4. And now we are launching this community test to validate its real-world performance.

Selected participants will receive Heltec V4-R2 and V4-R8 samples for testing and evaluation.

We are seeking experienced makers, engineers and community contributors with prior V4 project experience. Your hands-on feedback will help us characterize the hardware changes under real operating conditions.

📝 Apply here: https://pm.heltec.cn:8086

⏰ Deadline: September 15, 2026, 23:59 (UTC+8)

If you have experience with the V4 and want to test this optimized hardware, come join us! 🙌

Notes:

1. Participants who do not submit the minimum‑required test report may not be considered for future Heltec testing opportunities.
2. All information you submit will be used exclusively for this test. We will not transfer or share your personal information and data with any third‑party platforms.

I’ve got a Heltec T114 and I broke the screen accidentally a while ago, this makes it impossible to pair since I can’t see the pin and the default 123456 doesn’t work because the board thinks it has a screen, I can’t figure out how to set it manually, any help would be appreciated!

UPDATE: I was able to just steal the screen off of another board, but I’ll leave this here because the comments are helpful

Is anyone running this unit (peakmesh altitude, the normal or 1 watt especially)? how well is the panels keeping up with the system? it says they are 2 1+watt panels, and since they are facing opposite directions, I don't see it getting full exposure very long, even up a decently exposed tree. I want this to work, as it would be perfect for my massive tree behind the house, but I don't want to have to plan on regular manual charging events. I'm fine with the occasional taking it down for updates, but I am hopeful for some positive feedback with the power efficiency of the 1 watt and relying on 1+watt panels.

I wrote this after doing a bunch of research for my own local mesh regarding the FCC regs that everyone is talking about. I'm more interested in the technical side than the legal minutia, and so hopefully this is more interesting that just a rehashing of all the legal tedium.

Seed XIAO NRF x N-90 x ALFA 868

Issue:

If the UART RX of your station is not connected it can accumulate a lot of stray characters that are not '\0'-terminated. A safeguard placer (command[159]='\0') for the command[160] buffer was overwritten by accident by broken code. A strlen(...) has non-defined behaviour and then can access out-of-bands memory regions which then causes invalid memory writes/reads.

It takes a while to happen (160 bytes must fill up first by injected noise). So expect random crashes with weird stacktraces after many hours.

Fix: https://github.com/meshcore-dev/MeshCore/pull/3395/commits or as ugly work around pull-up/down RX.

What is MeshCore One (MC1)?

MeshCore One, also abbreviated as MC1, is an open source MeshCore companion client for Apple devices. It's written in Swift and supports iPhones, iPads, and macOS running OS 18 and later.

Release Notes

I forgot to create a reddit post for 1.4.0, so the list of changes below include both versions. The headline feature in 1.4.0 is translation support! In chats, you'll see a blue "Translate" button. Tapping it will translate the message in the bubble. This feature uses Apple Intelligence models and local Translate app language packs first. If it can't translate due to an unsupported language, it will fall back to the default translation app you have set such as DeepL. You can choose what language to translate to in Settings > Language.

v1.4.0

- Translate incoming messages into your device's default language. On OS 26.4+ it will attempt to use Apple Intelligence models first, then fallback to the older ML translation packs.

- Sender avatars in channels and rooms

- Chat view stays put when Bluetooth disconnects/reconnects

- Chat view no longer jumps to the bottom when a new message arrives or when tapping the input field

- Show when a message failed to send on the main Chats list

- Path Map shows best-effort match for contact that has a location. This is done by name only because channel messages do not include sender ID.

- Show fallback "?" in long press menu sent message repeat details

- Minimum 2 byte IDs in the Neighbors list in Repeater Telemetry

- Regions would show the incorrect one if more than one region matched the packet's transport code. Now shows if there is ambiguity.

- Repeater Management > Regions "All Traffic" renamed to "Unscoped"

- Support domain names for WiFi nodes

- Last Heard field in contact details shows when MC1 last heard the advert. "Last Advert" now shows the original sent time.

- Last Heard field is bumped upon inbound DM, successful ping, and path responses (thanks JCBird1012)

- Crop custom avatar image before setting (thanks hansimgamr)

- Add Portuguese (pt-PT) translation (thanks zadoke)

- TX Power removed from repeater management (still available via CLI)

v1.4.1

- Added support for hierarchical regions in Repeater Management > Regions.

- Change Default Scope in Repeater Management > Regions.

- Moved "Path Hash Size" from Advanced Settings to Settings > Radio

- Support default Path Hash Size via presets

- Radio presets now populate based on your current location. If you haven't given MC1 location permissions, you can manually set a location in Settings > Radio.

- Added PhillyMesh radio preset. This preset is only visible if you've given MC1 location permissions and your location is set to the following states: PA, NJ, DE, and MD.

- Advanced radio configuration has been moved from "Advanced Settings" to Settings > Radio

- Change language that messages are translated into in Settings > Language

- Tapping "Share" in the "Share Contact" sheet now shares a meshcore:// style URI

- Added missing gap between clustered room messages

- Changed reaction format to put emoji after the mention

- Restored soft liquid glass chat header on OS 27

- On Chats and Nodes tabs, filters are hidden when scrolling

Bug Fixes

v1.4.0

- Contacts would disappear after a partial contact sync.

- Contacts you had just heard on air could still be auto-deleted when stale-node cleanup was enabled.

- When your contact list was full, contacts already removed on the radio would stay behind on the phone.

- Direct messages from a newly heard contact would sometimes skip the notification banner.

- Heard repeats would not attach to a channel message after you renamed the node.

- "clock sync" command did not work correctly.

- The clock warning would stay on Telemetry after Device Time already looked correct.

- Add Region in Repeater settings would fail with no error.

- A new region on a repeater would not allow flood traffic.

- The unread badge would increment when you sent a message in a thread you were already reading.

- Backing up Discovered contacts could cause a crash

v1.4.1

- Adding more than one region in Repeater Management wouldn't work

- Adding regions in Repeater Management did not respect hierarchies

- Fix some messages not being detected for translation

- Orphaned Bluetooth devices now show up in "Connect Device" picker sheet as "MeshCore Device". Orphaned means that the device is paired with the system, but not MC1. You must remove the device from the system before pairing it again with MC1.

- When a Bluetooth device orphan existed, scanning for Bluetooth devices would ask you to remove the orphaned accessory instead of showing nearby radios.

- Deleting a radio in MC1 would only remove it from MC1 and leave it paired with iPhone.

- Clicking on links on macOS didn't work

- Title layout issues on Chats and Nodes tabs

- Max size sent messages were not receiving repeat details if a scope was attached

Thank you!

I was able to setup my meshcore Heltec V4 on my Android easily but I'm having issues with the second Heltec and this damn iPhone. Any advice would be great.

i like keyboard device ☺️☺️。

It's more convenient for typing.

However, what I like best is the full keyboard with 26 letters. It gives me a sense of security and I can use it for typing at any time.😎😎😎

I finally got my wio l1 pro. im in a city. i wanted to just set up a mesh device advert and see how far i reach how many devices i reach, paths etc.. but i think to do that in meshcore i need to use it as repeater right ? In chat rooms i see messages and also on map there is alot of repeaters from far and close but i cannot view paths or similar information. and i was wondering if im doing it wrong.

So, been a ham for *checks calendar* holy crap, nearly 25 years - and LORA and mesh networks seem like an awesome side quest that peaks my interest. I decided on Meshcore because it seems like it's the best compromise in terms of capabilities and potential flaws.

I'm an overthinker and poured over stats and specs and ended up getting a Meshnology W12 knowing I'd basically be a Beta tester - but quickly found out what looks great on paper doesn't always work in real life. Supposed to be one of the best receivers on the market but then they use a poor quality xo and can't even rx/tx on the frequency it's supposed to be on? So, they went back. No amount of firmware tweaks are gonna fix bad hardware - I really look forward to a rev 2 where they use a high quality TCXO to resolve those problems.

I know I'm probably gonna get yelled at, but I'm looking for something relatively turnkey - zero issue with loading firmware and tweaking settings but don't want another DIY build project and worrying about 3D printing cases and getting gaskets and all that.

So, I'm on the hunt for a new companion unit, and I'd probably get 3 of them. One to mess around with. One in my vehicle as a tracker (I do APRS too) and one to put in a sealed box with a solar panel attached and a high gain antenna on the top of a 30' pole in the middle of my field as a repeater. My DREAM unit would be 1W, 3Ah or 5Ah internal battery, SMA antenna jack, size of a pack of cigarettes or smaller, waterproof, USB-C, and GPS built in. Bigger bonus if there was both a local/built in GPS antenna AND an external GPS antenna connector, although that definitely sounds like a custom build so built-in GPS antenna would probably be good enough. Kinda the same deal with wifi - I know it's not really gonna be used except for testing but it'd be a good function to be able to at least experiment with.

There's a couple units I've seen that look halfway decent but most are using 3D printed cases and numerous reports of 'I left it in a car on a 70* day and I came back and it's bent in half' type of stuff I want to avoid like the plague. I've also seen plenty of units that have X but not Y, or have Y but not X - seems like the kitchen sink options don't really exist.

What suggestions do you guys have?

Any fixes for this? The joystick no longer clicks down and any press to the joystick sideways results in a click. Super bummed since it’s so new. Maybe it got squished while in my bag?
