Problem description

Python always returns code: 5 when connecting to the MQTT server using the paho.mqtt.client library. The account number, password, server address and port number are all right. The last check found that it is because there is no clientId set up, here is a record.

Solution.

Just add an Id for the client.

# since the client id cannot be duplicated, the current time is selected as unique IDclient_id = time.strftime ('% Y% m% d% H% M% slots), time.localtime (time.time ()) client = mqtt.Client (client_id) summary

Some MQTT servers need to set clientId to connect (for example, ejabberd), while some MQTT servers can connect without setting clientId (for example, emqx, iotdb).
