Is it possible to use the whole mesh as one message sending service, and possibly hook up a keyboard and screen to one particle, so that it can send a message to another particle in the mesh? Maybe with IRC, SMS, or any other form of getting messages across. ---

Should be doable 🙂 Mind you, they’re not just a computer you can install a ‘chat program’ on, so you’ll have to do some coding 😉 ---

> [@Enzonium](#): > > Maybe with IRC, SMS, or any other form of getting messages across. Why use anything else then the _intrinsic_ mesh protocol to communicate _inside_ the mesh? Sounds like calling or texting the person sat right next to you? While that may be fun (for some people) the real-life use in that is currently hidden from me as I could just directly talk to them (without extra effort - as this is the intrinsically human way to communicate) 😕 But I may well miss the point or misunderstand your request? Can you clarify? ---

What’s the range on these boards? I am thinking something crazy like 200 feet. I was thinking of setting up a local communication not reliant on the cellular network. If the range is only 20 feet, I could then understand. ---

I assume you can’t have 10,000 mesh-only (Xenon) boards talking through one single Wifi connected board (Argon). 5:1? 20:1? 100:1? UPDATE Found this in the FAQs: Mesh networks are generally limited in size by RAM availability. The Nordic nRF52840 has a generous 256kb RAM and promises to support larger Thread® networks than were previously possible with other chipsets. However, until we’ve completed …
