I'm trying to get OTA updates working on a new design using the ArduinoOTA component in the ESP8266 library on github. I have an ESP-07 attached via an FTDI adapter to a Win10 system running PlatformIO inside Atom.
I have built the example sketch as shown below and it uploads via the serial port and runs just fine. However, after enabling OTA upload in my platform.ini file, it always fails with no response from the ESP. I have scoured the web and tried the solutions that have helped others including setting a specific port number, enabling authentication (which fails to authenticate), and have tried different IP addresses (static and DHCP). I started with a board = esp07 and the same env, and have tried switching to nodemcu and nodemcuv2 without any change in behavior. I don't know how to troubleshoot this any further.
My sketch:
My platformio.ini file:
And, the error I get:
