message body routing from non-SDK leaf devices
the docs say to route messages within Edge properly based on the content of the body of the message, you have to set the content-type and content-encoding system properties, as shown in the sample below that uses the SDK
// Encode message body using UTF-8
var messageBytes = Buffer.from(messageBody, "utf8");
var message = new Message(messageBytes);
// Set message body type and content encoding
message.contentEncoding = "utf-8";
message.contentType = "application/json";
However, for a client that does not use the SDK, and instead uses straight MQTT such as the Paho client (as in this example), how do you specify those system properties? the IoT Hub docs (not edge) say that you can add a property bag of properties to the topic, but that doesn't seem to work for Edge.
So how can I route messages within Edge, based on the body of the messages, from non-SDK leaf devices?
