wdt reset

P.S. connection is successful if use ESP8266 Core (2.4.0-rc2)

vshymanskyy commented 6 years ago

This is caused by another bug in the Core. Hopefully fixed with: https://github.com/esp8266/Arduino/pull/4105

Workaround

With 2.4.0 the workaround would be to select Tools -> lwIP Variant -> v1.4 Prebuilt. Open-source variant should also work.

Refenz commented 6 years ago

@vshymanskyy Thanks! The workaround works fine.
