Struggling with Secondary Channel

Android app 2.0.14
3 915Mhz TBeams 2.0.15

I’m struggling getting a “Secondary” (private) Channel setup on my main node via CLI.

Then I want to share the QR code/Key to my other 2 nodes.

I would like to use CLI as much as possible so I can recreate the channel when i upgrade firmware (unless the config back will save the channel and key info)

Need help!!

Any assistance would be greatly appreciated!!

Have you reviewed the channel configuration page in the docs? If so, what issue are you running into setting via CLI? Channel Configuration | Meshtastic
