From 46cdb3ffd05d2f495695ea2acf7799dcac0ba280 Mon Sep 17 00:00:00 2001 From: C Freeman Date: Thu, 16 Jun 2022 08:39:20 -0400 Subject: [PATCH] Fix crash on read Networks when not connected (#19588) * Fix crash on read Networks when not connected This happens when running the example apps on linux with the wifi feature enabled (--wifi) because the device is actually connected via ethernet and wifi is not connected. This could happen in a prod device if > 1 network type was supported.
