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)
- 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.)
- Naming and Behavioral Conventions
- MQTT-ID
- devices
- capabilities (reporting)
- topics
- Pitfalls
- Fun with power LAN adapters (don't plug in your fridge)
- Returning pointers to method-scope variables
- Challenges
- Updating device configuration (ie, MQTT/ WLAN)
- Updating device code
