The server is located in the USA and the response times can be to high. MQTT之 PubSubClient 库. My daughters and I did a wearable knapsack project. See the MQTT_connect // function definition further below. Outbound configurations allow you to publish (send) an MQTT message to the MQTT broker when an item receives a command or state update, and other MQTT clients that are subscribed to the given topic on the same broker, like Arduino devices for example, will receive those messages. I had this problem with a Dell Wyse 5010 zero client, we ended up needing to update the firmware because of some problem it had with our certificates. Verify that you are logged onto the network and then try connecting again. On the whole this looked to be working okay, but we have now come across a problem which I am. Use this function if you need to restrict network communication over a particular interface. You can call tls_set() without setting a client side certificate or key by setting those parameters to NULL in C or None in Python, but the CA certificate is always required, unless you are using TLS-PSK. connect returns false, the connection has failed for some reason. NodeMCU x 1 pcs 2. The Cumulocity MQTT implementation uses SmartREST as a payload.
