Application layer converting MQTT messages to internal Rest APIs

[maheenmumtaz-tess]

Hi all,

Do you know if an application service exists already which receives external mqtt messages and converts them to internal APIs used by EdgeX services (and vice versa)? I want to keep my edge communication with cloud solely on mqtt interface if possible. And before I develop an application myself I was wondering if anyone else had felt a similar need and had a go already? Thanks!

There is no existing service to do that, but the App functions SDK supports the mechanism you need.
https://docs.edgexfoundry.org/4.0/microservices/application/details/Triggers/#external-mqtt-trigger
https://docs.edgexfoundry.org/4.0/microservices/application/sdk/api/AppFunctionContextAPI/#clients

You can develop your own App Service based on these utils.
