scale of network #1

Interesting app :+1:

At which scale of network does the app work? Only on the same internal home wifi network e.g. 192.168.0.x with subnet 255.255.255.0?

Does the same channel ID enable communication between multiple devices?

Hi! Thank you for comment!

App uses simple TCP/IP peer-to-peer connection, so actually it can work at any scale. The only question how each app can find each other. Currently it use Android NSD (the same as Bonjour by Apple), which in turn use MDNS (multicast DNS) protocol. MDNS usually works on a local network segment.

I have an idea to add a possibility to establish a connection by hands as well.

Does the same channel ID enable communication between multiple devices?

Yes, same channel supposed to work for multiple devices. Originally the idea was to have a possibility to create a multiple number of channels, but it was quite difficult, so currently it has only one channel.

It might be possible to "pair", or link devices, using QR Codes, NFC, or bluetooth, even encrypting links. Actually, one could send an "invite" farther, perhaps, similar to "serverless" XMPP sessions.

Hi, thank you for idea. QR codes, NFC or Bluetooth pairing probably will work, but they will work only on a very close distance. It is not so useful for such application. XMPP serverless messaging use the same discovery (zero-configuration networking)

I'm talking about how each client "finds" one another. Do we really want to chat with totally random people? Some might, but that's not really useful.

In addition to, perhaps an intent, to invite via, QR codes, NFC or Bluetooth, there should be a way to share an invite over e'mail, SMS/text, XMPP, and otherwise.

Well, if you take a real walkie talkie device, you choose a frequency/channel and share it with your friends, so you can talk to each other. No random people with this app, only people connected to the same WiFi network...
