Hi

I am sendig to mosquitto the following:

(in a dos window),

and while the subscribe is running in eclipse (method doSubscibe(), ..)

OK, I answer to myself, the correct string is:

mosquitto_pub -t Initoken/clientid/heater/data -m {\"sentOn\":1511970625597},\"metrics\":{\"temperature\":55}

with escape to the quotes.......

Hello,
I'll suggest to have a look at the following document that describes the expected format for the simple JSON: https://github.com/eclipse/kapua/wiki/K-Payload-JSON-Format#simple-json-encoding

Best regards,
Matteo
