Ultrasonic Serial Read Issue #14
Description
When ultrasonic is not connected, but turned on in settings, the ESP32 restarts in loop. The primary issue is that the Serial Monitor for ultrasonic returns garbage values even when nothing is connected and ESP32 tries to make sense of it and fails. The secondary issue is that it is running on CORE 0 and hence there is some kind of issue that is not faced by CORE 1 a.k.a. loop(). I'll check it in detail later.
