Public Channel Removal Stops Node From Working

I am setting up a node with a display to deploy to an individual who only needs to see messages through a private channel.

When I remove the public channel and set up the private channel, no messages are received and sent messages fail to send. If I add the public channel, messages work once again.

Am I missing a setting, or does the system need the public channel to send and receive messages?

Thanks for your time!

I’m seeing the same issue. It appears that if your channels are not in the same order, they can’t talk even if the name and psk are the same. So once you delete the public channel, the private channel is now primary (“0”) and it wont communicate with devices where the same private channel is secondary (“1”). Even if you keep the same channels on the list and flip the order, it breaks it. The only way I see to make this work is to have the private channel as primary on all devices. Then for the other nodes, keep LongFast and make it the secondary channel. But then these nodes will only communicate with other nodes that also have their public channel as secondary, which kind of defeats the purpose of keeping a public channel open.

Not sure if this is how it was intended to function, but it’s what I’m seeing in testing with Android devices.

Hey @MtTopGuy, I had the same issue. Did not see your thread until now. I posted the same issue yesterday, then stumbled across the solution on this page, even though I had been over this page many times before. It says:

Hope that helps.
