FOUND THIS SERVER: https://github.com/nailbuster/myWebServer that seems to incorporate all I found and more in a clean library.

to enable OTA upload in myWebServer uncomment this line :: //#define ALLOW_IDEOTA //define this to allow IDE OTA, good while debugging.... here :: https://github.com/nailbuster/myWebServer/blob/master/myWebServer.h#L48

The above server proving nice and useful - Participating in new work with Teensy here :: https://github.com/FrankBoesing/FlexiBoard Working with IDE 1.6.12 and ESP_Arduino Rev 2.3. Current Update here: https://github.com/FrankBoesing/FlexiBoard/blob/master/extras/ESP8266/README2.ArduinoESP.md

Using Arduino on Teensy and ESP8266

Work in Progress: GOING WELL - multiple ESP units tested with OTA and now Serial program over Teensy USB to Serial

• NOTE: Arduino IDE 1.6.7 is the first release that provides support for ArduinoOTA library

This link to working with SPIFFS file system on ESP: http://esp8266.github.io/Arduino/versions/2.1.0-rc1/doc/filesystem.html [ newer 0.2.0 working for OTA SPIFFS upload: https://github.com/esp8266/arduino-esp8266fs-plugin/releases ]

Connected and powered by a PJRC Teensy 3.2.

ESP units are a 12E and a onehorse unit from Tindie : https://www.tindie.com/products/onehorse/esp8266-add-on-for-teensy-32/

A second onehorse unit with PCB to Serial2 used in latest update, can wire to ESP_generic the same way. Initial code (commented out) used a Serial3 PCB unit with wires from Rx/Tx to Teensy ALTERNATE Serial2 pins on a FrankB connectorboard.

Added: Example for Teensy 3.2 (will work on 3.1 with external ESP power) Proxy sketch that routes Serila# to Serial/USB for debug or programming. USB commands can be issues to: PROGRAM [P :: reset to pgm mode serial], RESET[R}, ESTOP [E=ON, e=off] [Command LETTERS preceded by ` (left apostrophe character). All other USB imput echoed to ESP.

Code functions well - is a mess to read - and poorly commented, some notes here on functionality.

First "HelloServerOTA" example for ESP8266 --- Started with HelloServer ESP example then merged added OTA code from BasicOTA example

• Edit the userssid.h file in the sketch folder to supply your network SSID and password
• The sketch cycles power to GPIO 12,13,15 where I stuck an RGB LED, it puts out serial data, presents web text.
• Incorporates Arduino OTA Port based uploading
• Use build for your ESP unit, I set mine to 1M ( 256K SPIFFS ) to allow OTA code to fit at 259K it is 33% code space
• [pending] Bad code crashing into wdt (watchdog timer)? - added setup() pin read to skip user code except OTA after WiFii
• Added Serial receive echo back our Seial, it seems SerialEvent not supported so added to loop()
• Any NEW code or code that can CRASH needs to be under 'if (!ESTOP)' - you can then set the declared pin high on Teensy (E) and reset (R) to preserve the OTA code ability to recover from crashing resets - I did thie ONCE with a SPIFFS edit, and implemented this failsafe.
• OTA uploads are 3-6 times faster than Serial uploads, and actually seem more reliable
• Check your SPIFFS and other settings in tools as the IDE can reset them - in one case that trashed my OTA code as it shrunk the program area.

First AutoRefresh "FirstPage" Client side Web Page set: start index.htm ---Sample auto update browser script to monitor ESP8266

• Edit menu.htm for starting IP if you have a fixed one to save editing it (include subpage if you make one like /t )

  • edit :: ESP IP:

• Press LOAD to show the web page in lower frame

• Press AUTO button for 2500ms auto refresh, edit menu.htm to adjust timing 500ms works, when no multi unit collisions

  • setInterval(loadeip, 2500)
