mqtt connection with clientid, username and password about asyncmqtt_generic

[khoih-prog]

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

AsyncMQTT_Generic/src/AsyncMqttClient_Generic_Impl.h

Lines 253 to 259 in 9bc9c19

	AsyncMqttClient& AsyncMqttClient::setCredentials(const char* username, const char* password)
	{
	_username = username;
	_password = password;
	return *this;
	}

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

AsyncMQTT_Generic/src/AsyncMqttClient_Generic_Impl.h

Lines 224 to 229 in 9bc9c19

	AsyncMqttClient& AsyncMqttClient::setClientId(const char* clientId)
	{
	_clientId = clientId;
	return *this;
	}

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,
