### Hardware: Board: ESP WROOM 32 Core Installation/update date: 02/08/2017 ### Problem: For at least two people on Gitter the commit ca7f6cc516ce842cf7c6b35dbde4b0d4a5a86404 Author: me-no-dev <hristo@espressif.com> Date: Tue Aug 1 08:51:04 2017 +0300 Update IDF libs to 9314bf0 broke ArduinoOTA. The symptom is that the update file is transfered, as it seems completely, but then the updater stops with error 4 (end failed). ### Sketch: Happens even with the standard BasicOTA example Both reporters used a ESP WROOM 32 Breakout Board.
