<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> |
