Esp-link uses
-------------
The simplest use of esp-link is as a transparent serial to wifi bridge. You can flash an attached
uC over wifi and you can watch the uC's serial debug output by connecting to port 23 or looking
at the uC Console web page.
The next level is to use the outbound connectivity of esp-link in the uC code. For example, the
uC can use REST requests to services like thingspeak.com to send sensor values that then get
stored and plotted by the external service.
The uC can also use REST requests to retrieve simple configuration
information or push other forms of notifications. (MQTT functionality is forthcoming.)
An additional option is to add code to esp-link to customize it and put all the communication
code into esp-link and only keep simple sensor/actuator control in the attached uC. In this
mode the attached uC sends custom commands to esp-link with sensor/acturator info and
registers a set of callbacks with esp-link that control sensors/actuators. This way, custom
commands in esp-link can receive MQTT messages, make simple callbacks into the uC to get sensor
values or change actuators, and then respond back with MQTT. The way this is architected is that
the attached uC registers callbacks at start-up such that the code in the esp doesn't need to
know which exact sensors/actuators the attached uC has, it learns thta through the initial
callback registration.

More info and sample code forthcoming...
Outbound HTTP REST requests
---------------------------
The V2 versions of esp-link support the espduino SLIP protocol that supports simple outbound
HTTP REST requests. The SLIP protocol consists of commands with binary arguments sent from the
attached microcontroller to the esp8266, which then performs the command and responds back.
The responses back use a callback address in the attached microcontroller code, i.e., the
command sent by the uC contains a callback address and the response from the esp8266 starts
with that callback address. This enables asynchronous communication where esp-link can notify the
uC when requests complete or when other actions happen, such as wifi connectivity status changes.
Support for MQTT is forthcoming.
You can find a demo sketch in a fork of the espduino library at
https://github.com/tve/espduino in the
[examples/demo folder](https://github.com/tve/espduino/tree/master/espduino/examples/demo).

<p>The REST &amp; MQTT support uses the SLIP protocol over the serial port to enable
the attached microcontroller to initiate outbound connections.
The REST support lets the uC initiate simple HTTP requests while the MQTT support
lets it communicate with an MQTT server bidirectionally at QoS 0 thru 2.</p>
<p>The MQTT support is in the form of a built-in client that connects to a server
using parameters set below and stored in esp-link's flash settings. This allows
esp-link to take care of connection parameters and disconnect/reconnect operations.</p>
<p>The MQTT client also supports sending periodic status messages about esp-link itself,
including Wifi RSSI, and free heap memory.</p>
