- * Arduino 1.6.1 from esp8266/Arduino: Apply the instructions from Bynigelbe. In other words, update the esptool entry in platform.txt and select esptool as the programmer
* Arduino 1.6.3 from Arduino.cc with sandeepmistry/esp8266-Arduino applied: Apply the instructions from Bymactro about updating the runtime settings in platform.txt
Finally, after you modify platform.txt, be sure you reload the tool chains from Visual Micro: (using Tools => Visual Micro => Reload Toolchains). Otherwise the changes you made won't be picked up.
