Re: [paho-dev] Fw:Anyway to get the detail connection error from paho-mqtt-client0.40


if using IMqttAsyncClient
IMqttToken connect(MqttConnectOptions options, Object userContext, IMqttActionListener callback)
You can set a IMqttActionListener, and you will be notified if connect failed,  and get the reason code and cause from MqttException.

if using IMqttClient
IMqttToken connectWithResult(MqttConnectOptions options), check IMqttToken.getException()

Hi all:


Sorry to boring you.


For paho-mqtt-client0.4, is there any way to get the detail connection error while doing a mqtt connection like mqttclient.connec()?

Sometimes I need to know if the connection was rejected either y server cause of the incorrect username or password or by the unstable network connection.

BTW, I also wanna if “connecionlost” API can provide the detail lost reason, like “clientid login in other place, connection closed” or something else.
