Hi Jose,

Does Fiware support MQTT protocol w.r.t. IoT? Please give reference of some examples if possible.

In “Tour Guide”, I am able to Send Measurement using HTTP protocol and temperature value is being updated in Restaurant Entity.

But when I am doing following PUB/SUB, it is not updating the value of temperature in Entity. It is showing value in SUB console, but Restaurant entity is showing older value.
Please suggest.

mosquitto_sub -h <HostIP> -u <username> -P <password> -t /tourguide-devices-Franchise1/0115206c51f60b48b77e4c937835795c33bb953f-kitchen-temperature/attrs/t

Dear Krishan:

Yes it does, FIWARE can support MQTT protocol.
Could you give me more details about this issue? Are you using some Fiware IotAgent, if yes which version is? About Fiware Context Broker which version are you using?

Feel free to contact me

Thanks you

Hi all,

  Where are we regarding this question from TechMahindra?  Can someone
elaborate?  Maybe you have followed up just among the two of you, but I
was wondering.

  Cheers,

  Juanjo
