MQTT example using the Freescale FRDM-K64F platform without additional hardware.
Dependencies: EthernetInterface MQTT mbed-rtos mbed
This is a simple MQTT demo that does the following:
- connect/disconnect to the MQTT Dashboard public broker (broker.mqttdashboard.com)
- subscribe to a user-defined MQTT topic
- publish messages from the FRDM-K64F board when SW2 or SW3 is pressed
- receive messages from a web dashboard client to change the color of the LED
- send serial output regarding connection status and MQTT messages sent/received
The web client code can be found at the following URL:
https://github.com/msbaylis/frdm-k64f-mqtt-dashboard.git
NOTE: make sure you change the #defines in main.cpp to specify your client ID and MQTT topic. I used the MAC address of my FRDM-K64F board without colons for the client ID. Assuming you're board is properly connected to a network, the serial output should display info including the board's MAC address.
