Help¶

Azure IoT Hub uses dynamically constructed topics to transfer information elements such as response codes, direct method names and property bag keys and values. This option configures the maximum length of such an element. Note that all values are also represented as strings, regardless of their content, so a boolean or a number will require its length as a string, and not the size of its binary representation.

Direct dependencies¶

AZURE_IOT_HUB

(Includes any dependencies from ifs and menus.)
