This function is called when the MQTT client for the gateway receives an incoming message on a topic. If the message is processed by the application, return true. If the message is not processed, return false. This function is called on a separate thread, so no stack calls should be made within the implementation of this function. Instead, use a global variable in that function to communicate the message arrival to a stack event or timer running from the main loop.
A string containing the topic for the message that arrived. While the underlying MQTT libraries allow NULL characters in a topic, NULL characters are not supported in this implementation so the
topicparameter can be assumed to be NULL terminated.
A string containing the payload for the message that arrived.
This function is called when the state of the MQTT client changes.
Contains the new and current EmberAfPluginTransportMqttState state.
