From 2763097e1029e240aa713364654e8712b299c42e Mon Sep 17 00:00:00 2001 From: Isak Westin Date: Mon, 26 Sep 2022 15:01:09 +0200 Subject: [PATCH] mesh: Correct HB sub state updates If heartbeat subscription is disabled, all fields should be set to zero but collected data should be preserved. If HB subscription is enabled, the collected data should be reset (which includes Min Hops = 0x7f). HB subscription is disabled by setting any of the following fields to zero: Source, destination or period log. HB subscription is enabled by setting all the same fields to valid values.
