From 3806ad73e120da81912d8201bfbf247f926657fe Mon Sep 17 00:00:00 2001 From: Markus Theil Date: Tue, 30 Jun 2020 14:19:04 +0200 Subject: [PATCH] tests: DFS test for mesh Add a test which uses a DFS channel, waits for CAC afterwards successful mesh join and then triggers a radar event and checks if the mesh comes up again on the same device.
