Mesh STA has two methods of mesh discovery, either using active scanning or passive scanning.
Passive scanning is based on beacon generated from other peer mesh STAs as Bob mentioned. Active scanning is based on triggering of probe request from mesh STA itself and wait for probe response from other peer mesh STAs to discover the neighboring mesh STAs. Use iw command to do that "iw mesh0 scan meshid". Off course, we can only start the mesh peering if mesh ID is matched. --- Chun-Yeow On Tue, Jul 15, 2014 at 12:04 AM, Bob Copeland <[email protected]> wrote: > [please don't use HTML-formatted mail.
