In my console I get that the connection was sucefull, but when I see the AWS server, I can´t find the data. I don't know if it's due to a code problem or caPath Certificate, beacuse I don't know where I can find. So I get it forn this link link text. In my console I get :

I'm sending data with a time to 10seconds.

Could you explain me, what de you tried to say in this " I would also implement the on_publish callback.

¿This? Sorry if my question it's basic- I´m new using this module and sendding data to AWS.
def on_publish(client, userdata, mid):
print("Message published: " + message)

# message published, disconnect
client.disconnect()

client.on_publish = on_publish"
