MQTT Secure via HTTPS Websocket Example

Uses an mbedTLS socket to make a very simple HTTPS request over a secure connection, including verifying the server TLS certificate. This setup uses the secure MQTT broker at mqtt.iotcebu.com by default, if you need to setup your own secure MQTT broker, do a make menuconfig to change the default settings. Don't forget to change the certificate file cert.c with your own server.

Example MQTT

• Periodically publishes temperature and humidity data to MQTT and sleep
• IO 4 is connected to an LED (to indicate the MCU is active)
• IO 16 is connected to the out pin of the DHT22 (Temperature and Humidity) sensor

PREPARE

1. change main/cert.c -> server_root_cert
2. do a "make menuconfig" to change the default settings

(Hint: today mbed_ssl without WebSockets is unstable, i.e. reconnecting is needed some times, searching for reasons...)

INSTALL

• make menuconfig
• make -j8 all
• make flash
