can it support send a message to specific target module? about iot-edge-v1 HOT 5 CLOSED

Do you mean that the gateway application needs to send a message to a module? Or another application on the same machine?

Generally, out-of-band communication like this is not handled by the SDK.

Can you provide a more specific example? Or maybe a pull request? ;)

from iot-edge-v1.

I mean sending to a broker module managed by the gateway.

for example, we send data to module A for prcessing, then to module B for further processing.

from iot-edge-v1.

When you configure modules A and B in the gateway, you can add a link to the configuration so that messages sent from module A and delivered to module B, like this:

"links": [
  { "source": "A", "sink": "B" },
  ...
]

Does that give you what you're looking for?

Hi @Kevin0626,

To add more, is your scenario like this?
Having a Module A, Module B and Module C and you want sometimes send messages from Module A to Module B and sometimes from Module A to Module C? Is this your scenario?

If so, what you can do is filtering the message using Message Property, (like defining a Content-Type, for example.

I would advice to try to design your scenario so modules send target messages to other modules (using direct links), but if you sometime needs to implement the scenario above you can always use Message Properties.

Hope this helps,
