Secondary channel routing

Support
1

Simple questions about the roles of secondary channels:

  1. If I establish a secondary channel with my own PSK, nodes on other channels won’t route my traffic, right? Is there no way to piggyback? “Hey, send my private channel data for me, please and thank you.”
  2. Is there a way to route encrypted traffic on a shared/poorly encrypted channel (like LongFast with its known PSK) to a specific node? Like a private message to a friend, where the metadata is visible but not the content.

I gather that LongFast is a bit like a public chatroom.

Nodes that can receive the data (ie have the same Lora Modem settings), will rebroadcast messages, even if doesn’t have the channel key to decode the message. (will forward without reading the contents. )

You can do direct messages over private secondary channel.

Direct messages over the default channel wont be private, as the key is well known. Like taking in a public room, might be having a private convesation in a group, but technically can be heard by others if they try.

Thanks, that makes sense now.

Is there any way to change the channel on the Android app? I added the new channel to my radio config but don’t see any way to send a message on another channel.

Edit: nevermind, I see it shows up in the list of messages, similar to how “LongFast” shows up as its own channel.
