Android Question Jmqtt official Android MQTT client cannot link

[cxdzbl]

I've used the example code for this page:
https://www.b4x.com/android/forum/threads/jmqtt-official-android-mqtt-client.59497/

mqtt.Initialize("mqtt", "tcp://m13.cloudmqtt.com:11043", Rnd(0, 999999999) & DateTime.Now)
Dim mo As MqttConnectOptions
mo.Initialize(name, password)
Change my registered user name and password, but can not link, return error information is 5, I have no right to access.

Does it work with a local broker (mosquitto or an embedded broker)?

Because our language barrier problem, always use software to translate your reply, is not accurate enough, so I do not understand your reply, I hope you can give me every step of the detailed answer, thank you.

Do not use CloudMQTT. Run Mosquitto on your PC and open the relevant port in Windows firewall. Does it work?

After installing mosquiitto, prompt when running under DOS：
2[main] mosquitto 16068 find_fast_cwd: WARNING: couldn't compute FAST_CWD pointer.please report this problem to the public mailing list [email protected]

Does it crash? You can also use the embedded broker: https://www.b4x.com/android/forum/threads/61548/#content

After continuous testing, chat_b4a is available, running well in GPRS or in WiFi network, thanks, the problem has been resolved, and the next step is to analyze the code.
