LFUtilities

This library contains various stuffs/helpers to Arduino like developments.

IMPORTANT NOTE : It is MANDATORY to include the fake file #include <LFUtilities.h> in your project otherwise Arduino IDE will not find other includes.

Duration

#include <LFUtilities/Duration.h>

Abstracts duration measurement.

  • Duration( void ) or void reInit( void ) - Starts a duration measurement.
  • unsigned long int Finished( void ) - End of measurement, return the duration in milliseconds.
  • unsigned long int operator &ast;( void ) - return the duration in milliseconds, up to the Fini() call or till now.

SafeMQTTClient

#include <LFUtilities/SafeMQTTClient.h>

MQTT's client with automatic reconnect facilities. Notez-bien : if SERIAL_ENABLED is defined, some debug messages are output to the serial tx.

  • SafeMQTTClient(

    • Client &client - Network client
    • const char *ssid, const char *pwd - WiFi's SSID and password
    • const char *bURL, int bport - MQTT broker URL and port
    • const char *clientID - MQTT clientID
    • const char *logtopic = NULL - Root of the logging topics (if not set, no logging is done)
    • bool clear_session = false - Among other things, with clean session set, it's not possible to receive asynchonously messages. ) - Constructor

  • bool connectWiFi( Duration *duration = NULL, uint32_t maxtries=SMC_WIFI_MAX_RETRY ) - Connect to the WiFi network (implies connection to MQTT as well).

  • bool connectMQTT( Duration *duration = NULL ) - Connect to the MQTT broker (normaly, there is no need to call it directly)

  • bool connected( void ) - Are we connected to the broker ?

  • void setMQTTMaxTries( uint32_t val ) - For how long are we trying to connect to the broker (seconds)

  • uint32_t getMQTTMaxTries( void )

  • void publish(

    • String &topic, - Topic to publish to
    • const char *msg or const uint32_t val - what to publish
    • bool reconnect=true - reconnect if the network is lost )

  • void logMsg( const char *msg, bool reconnect=true ) - publish a message

Published topics

  • topic/Message - Log messages
  • topic/WiFi - WiFi connection duration
  • topic/MQTT - MQTT connection duration
