IoT with AME - The Internet of things, with Arduino, MQTT, and ESP8266

Planned content

What would I like to write about?

  • MQTT
    • finite state machine of the protocol
    • most simple application (QoS 0)
    • encoding and decoding
    • more sophistication (QoS 1, 2), limits of the Arduino environment (like, conversational state)
  • The Stacks
    • HW stack: Arduino, ESP8266, additional hardware
    • SW stack: PubSubClient, Client -adapter, ESP8266 or, alternatively, AC_MQTT & AC_ESP8266
    • SW problems (SoftwareSerial, memory use, bugs)
    • HW problems (current spikes, general unreliability of the ESP)
  • Naming and behavioral conventions
    • MQTT-ID
    • devices
    • capabilities (reporting)
    • topics
  • Tools
    • AC.programmer (SPI programming, freed-up serial interface, 2k more flash mem, logging via I2C)
    • Monitoring MQTT publications with MQTT-Spy
    • MoquetteMon - Add-on to the Java OpenSource MQTT Broker Moquette (shows IP, QoS, subscribed-to and published topics etc.)
  • Challenges
    • Updating device configuration (ie, MQTT/ WLAN)
    • Updating device code
