mqtt connection with clientid, username and password #6

Closed darkcurrent closed 2 years ago

darkcurrent commented 2 years ago

Hello, this is a very cool library. But I am little bit confused about how to set clientid, username and password for mqtt connection. Could you help me please?

Hi,

Thanks for using the library and your nice words.

Normally, the username / password are required only by certain MQTT Broker. clientID is generated automatically by the library using MAC address, ESP chipID, etc.

If those are required, follow these steps

  1. For username / password, you can use function setCredentials(username, password) as defined in

https://github.com/khoih-prog/AsyncMQTT_Generic/blob/9bc9c19c5cc55b960b002f14b7fc252a30e1d855/src/AsyncMqttClient_Generic_Impl.h#L253-L259

  1. For clientID, use function setClientId(clientId) as defined in

https://github.com/khoih-prog/AsyncMQTT_Generic/blob/9bc9c19c5cc55b960b002f14b7fc252a30e1d855/src/AsyncMqttClient_Generic_Impl.h#L224-L229

If not using setClientId(), the clientID will be auto-created

As this is not a bug of the library, I'm closing the issue now and suggest next time, post on Discussions or Arduino Forum to get help.

Good Luck,
