Paul Kamp / Mbed 2 deprecated MTS_Dragonfly_Twilio_Sync_IoT_MQTT

Connecting a Multi-Tech Systems Dragonfly™ to Twilio's Sync for IoT Quickstart. Blink a dev board LED.

Dependencies:   MQTT MbedJSONValue mbed mtsas

Fork of DragonflyMQTT by miao zhicheng

Code to connect a Multi-Tech® MultiConnect® Dragonfly™ to Twilio's Sync for IoT: https://www.twilio.com/docs/api/devices

Uses MQTT over TLS and subscribes to a topic where you can control an LED. See also our Quickstart using this code, here: https://www.twilio.com/docs/quickstart/sync-iot/mqtt-multi-tech-multiconnect-dragonfly-sync-iot
