【E840-DTU】MQTT——ONENET - RF/Wireless - Electronic Engineering World - Forum (eeworld.com.cn)

Today, we tested our own MQTT server to prepare for the successful access of [National Technology N32G430] to the Internet:

1. Use the configuration tool to enter the configuration mode. Remember to select the baud rate of 230400. Fill in the clientID, user name, pwd, IP address, port, and subscribed topic respectively. Then save the configuration. After exiting the configuration, LINKB shows that the connection is successful.

2. Open the MQTTX tool and connect to the MQTTX server tool as well:

3. Send messages to each other and both can receive:

[Summary] Now that DTU is connected to the server, information can be exchanged. The next step is to use N32G430MQTT information to display the acquired data.
