GPIO15 and Serial Connection

Postby chessweb » Sun Nov 26, 2017 12:03 am

Working with NodeMCU (ESP8266-12E) and the Arduino framework I noticed that GPIO15 must be pulled to Low when a serial connection is established. Otherwise the serial connection does not work properly. What is the reason for that and is there a document where I can read up about this?
