Although everyone has their own reasons for exploring a new hobby, one of the driving factors behind the popularity of Meshtastic and MeshCore has been the incredible accessibility offered by off-grid LoRa mesh networks. You don’t need any expensive hardware or a license to get on the air — armed with a $20 microcontroller dev board and open source software, you could be on the mesh in minutes. Then came the really exciting part, seeing who else was out there. The low barrier of entry and ad-hoc nature of these projects meant there was a good chance you’d soon find yourself exchanging messages with other like-minded folks in the area.
Or at least, that’s how it used to be. With the recent revelation that their default radio configurations have potentially been in violation of the Federal Communications Commission’s (FCC) regulations governing amateur usage of the 900 MHz industrial, scientific and medical (ISM) band, the users and developers of both Meshtastic and MeshCore have been sent scrambling. Getting in compliance isn’t necessarily a technical challenge. In fact, Meshtastic has already introduced changes aimed to address the issue and anyone running the latest alpha release can be sure that their initial radio configuration will meet FCC standards.
But unfortunately, this introduces a new problem. While it’s easy enough to get new installations of Meshtastic and MeshCore operating in a mode that keeps the FCC happy, doing so breaks compatibility with everything that’s already been deployed. The community will be fractured into distinct strata depending on when they first configured their hardware, with an added dash of confusion from the more rebellious users who will undoubtedly refuse to migrate over to the new settings.
Since you covered the important bits, I’d add :
ESP32 if you want WiFi but short battery life, nRF52 if you want long battery life but no WiFi.
Will definitely probably want wifi, so ESP32 will probably be the route for that.
I breezed through the other replies and didn’t see anyone asking why you want wifi.
If you’re going to hang a node somewhere and have it solar powered, the nRF52 will give you waaaaaaaaay longer life and easier (solar) recharging. I’ve got nodes that have been out (unmaintained) for three or four years now, running on a 2,000mAh battery and 2x crappy 60mA@5v solar cells, and they’ve never dropped out as far as I can tell… even in deep winter when you shouldn’t be charging lithium-ion battery packs in sub freezing temps : )
I’m probably dumb, but I don’t see why anyone wants wifi from a LoRa node when all it does is rob power/longevity without adding any benefit that I can think of.
You can get a kit for $200 or so that comes with solar, battery, WiFi, Bluetooth, LoRa antenna, … it’s pretty much plug and play by that point.
Any recommendations on a quality full kit?
I have this one for Meshtastic and it works great, but uses Bluetooth for configuration rather than WiFi: https://www.seeedstudio.com/SenseCAP-Solar-Node-P1-Pro-for-Meshtastic-LoRa-p-6412.html
Same product but with Meshcore instead: https://www.seeedstudio.com/SenseCAP-Solar-Node-P1-Pro-for-Meshcore-p-6741.html
I don’t have this one, but it has WiFi as well: https://www.newegg.com/p/0XP-06T7-000M3?item=9SIC4NEKST8969
Without wifi lowers the power requirements, probably better suited for a solar setup. Not sure how reliable that last one would be, but worth a shot I’m sure.
Is there any difference in the hardware between Meshtastic and Meshcore? I didn’t think there was… but I haven’t been keeping a close eye on it.
I have a lot of RAK4631 based builds and I flashed a few from Meshtastic to Meshcore, said “meh”, then flashed back to Meshtastic. So … I assume no hardware difference. I think it’s mostly just the software/routing protocol that is different (which is why I stuck with Meshtastic).
EDIT: Also tried RNode (Reticulum) on the same hardware which was… interesting, but a silly protocol to have on a solely LoRa device.
Yeah I believe the difference is at the protocol layer. The links I provided come preloaded with either software respectively. I don’t think there’s a difference in the hardware of the two offers.
Thank you, I will check them out today.
I would add, be sure to turn off the setting that broadcasts your precise location. Unless you’re into that sort of thing, I guess.
