Topic: wolfMQTT v0.3 and MQTT Secure Firmware Update Example
The wolfMQTT v0.3 release adds a new example for secure firmware update. This example uses the wolfSSL embedded SSL/TLS library to hash/sign the binary image and send it over MQTT. The example has two applications. One is called fwpush, which hashes, signs and publishes the firmware image over TLS to an MQTT broker. The second is called fwclient, which subscribes to the example firmware update topic, receives the firmware image and validates the signature of it. This example is located in examples/firmware.
