Hi
I am trying to implement notifications using mqtt but the rest of operations using http (create AE, containers, subscriptions, etc)

Can we mix HTTP and MQTT bindings. If so, how to pass the <nu> element of the notification for mqtt?

I am using like this but it does not works:

<nu>mqtt://test.mosquitto.org/test/topic1</nu>

Thanks a lot
Alex

Hi there,
Protocol bindings are independent of OM2M core. You can interact with the same resources seamlessly using HTTP or MQTT.
The notifications in MQTT should be supported as there is an MQTT protocol binding plugin.
Could you give more information on the error you get and the logs of OM2M?

Be sure to have an MQTT client on the other side subscribing to the right topic and answering correctly when the verification request is sent at subscription creation.
