<p>The REST & 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> |
