Discover the best Meshtastic devices tailored to your needs! From solar-powered options like the RAK WisBlock to budget-friendly choices like the Heltec LoRa 32 V3, this guide covers various use cases. Whether you prioritize portability, ease of use, or advanced features.
How does this differ from walkie talkies?
The long range part I guess.
They can transmit any kind of data and be hooked to the internet if you like.
It is text-based only. And since it’s such a small amount of data, it can be transmitted a much longer distance.
There’s also the Mesh part where if two nodes (radios) are too far apart, and another node is in between, it can act as an intermediary/relay to increase distance. You can use ~4 nodes (3 hops) in this way.
Communications are also encrypted.
Oh this is making some sense to me now. Will this replace or augment iMessage one day?
Hehe no. It is text/emoji only. Best used in places where cell networks don’t exist, go down, or become saturated, or some combination.
Oh. Not even 20 years in the future? Never would have expected the fediverse or iPhones that can talk to satellites.
It could certainly easily be added as another backup communication method built into phones, yes. But among many other reasons, Apple doesn’t touch anything “open”, so if anything they would implement their own LoRa protocol.
Is 4 nodes the maximum able to connect?
Not sure what you mean by “connect”. You can connect hundreds of them in a mesh network (although the network will eventually become saturated if you don’t adjust), but message delivery is typically electronically limited to 3 “hops” for any particular message.
