Advert
MeshCore allows you to manually broadcast your name, position and public encryption key, which is also signed to prevent spoofing. When you click the advert button, it broadcasts that data over LoRa. MeshCore calls that an Advert. There's two ways to advert, "zero hop" and "flood".
- Zero hop means your advert is broadcast out to anyone that can hear it, and that's it.
- Flooded means it's broadcast out and then repeated by all the repeaters that hear it.
You can send advert on the APP. Also you can send advert directly on the device advert page.

Public Message
After you configure the LoRa, you can send messages in the primary channel. All nearby people in the same frequency band will hear it.
Private Message
The two devices only establish a connection when they have both received each other's advert.
