20160516 - Update !

We can talk !  Parts of MrlComm are now running on the Esp8266.  Did a full getVersion request and the data flowed !  ....  goodtimes....

Next is considerable cleanup..   MrlComm "should" be a library..   and then I "think" this should probably not be its own service ... its really just a reconfig of pin mapping (once working correctly) in the Arduino service...

Not sure ..

Here's MrlWifi (Borg'd MRL + Wifi) ... load it on the Esp8266 - then you can connect with a TCP serial port ...  I expect many revisions to be done to this to get it ship shape

TODO

  • how to determine if the socket is closed on the esp end ? - it does not 'throw an exception' ..
    need to know how to check..
  • massive cleanup
  • heartbeats ?
  • more functionality moved into WiFi capable MrlComm version
  • does Esp8266 support pwm on any GPIOs ?
  • Servos ?
  • Reading Digital & (one?) Analog ?
  • Testing like crazy
  • MrlComm needs to be library - which can accept a Serial or Wifi client connection
  • text interface to protocol ?

Since the Blender service Serial has been capable of raw serial data over TCP/IP.
I wanted to make sure it was still working - so I connected it to a netcat listener  (nc -l -p 2222)
STILL WORKY !!!

Next will be looking at the Esp8266 code for a socket server which the web server was probably built on...

Just tested the code and indeed it works, just for test I monitored the serial port after polling the IP address and MRLcomm TXed quite a serial data chain of info.... the ending part you see above.

Translated as "keep-alive"

first part " ª " translates as ....... magicnumber STX SOH SOH    ascii codes!! (edit:- er NO!! what was I thinking)

N.B. the ESP would not compile for me until I move the

#include <ESP8266WiFi.h>

a tad higher in the code flow circa line 176 .....else the ide complained.

So far I have already used 6 Pwm's working in parallel , so my guess is all usable pins can be pwm_ed
