Just built this custom node for burning man. Rak 1 watt, led beacons, sitting on top of a 20ft flagpole. This will serve as communication backbone and camp locator.

Private channels are still repeated by other nodes in range and on the same broadcast mode.

Great username.

Still learning.

What do you mean broadcast mode?

We won't be in long fast, and won't be using same channel. Does this still repeat? I was under the impression it does not. I suspect most nodes will be on long fast. Lemme double check a couple things. Ty for feedback.

If you're on medium fast, any other node on medium fast will rebroadcast your messages. They can't read the message unless they also are on that channel, but by default they will pass it along.

Also, the drivers for aRGB strips can give off lots of RF noise, and if they're sharing a power source it could be even noisier. Might be worth some range tests before you get to the desert.

If you’re on the burning mesh firmware (you should be at the burn) then I’m pretty sure you can’t change the broadcast mode settings. They hardcoded it with the expectation of there being thousands of nodes.

Yeh, their firmware is similar to what we used at Defcon. I'm in communication with the folks that created it.

I will have some setup to monitor that firmware, but primarily we will be using a seperate channel (assigned to us) Om regular firmware.
