Question 1

What is flood advertising on MeshCore?

Accepted Answer

Flood advertising is when a MeshCore LoRa mesh node broadcasts its presence (advert packets) across the entire mesh network. Each advert is rebroadcast by every repeater, so frequent advertising consumes significant shared channel capacity and increases packet collision risk for all users.

Question 2

What is the recommended flood advertisement interval?

Accepted Answer

The recommended best practice is to set your flood advertisement interval to a minimum of 24 hours. More frequent advertising than this is considered excessive and contributes to mesh congestion.

Question 3

How is collision risk calculated?

Accepted Answer

Collision risk is estimated using the pure ALOHA model: P = 1 - e^(-2G), where G is the channel offered load based on all observed packet events in the past 24 hours multiplied by the per-packet airtime (~431ms for SF7 BW62.5 CR4/5).

Question 4

What is the Cascadia Mesh Network?

Accepted Answer

The Cascadia Mesh Network is a community-operated MeshCore LoRa radio mesh covering the Pacific Northwest region of North America, including British Columbia and the Pacific Northwest United States.
