For some reason when building this recently on Debian Jessie amd64 connection fails at startup.

The SocketWrite fails with a connection timeout error. Basically the FPSocket^.Connect is returning before connection is established. Checking LastError after the connect shows "Operation in progress".

I've downloaded the files both of them and replaced them over the old 2013 MQTT and MQTTReadThread files. Then, I made all the appropriate changes in my software to reflect the changes in these new files in my program and my program complied with no problems. However, when I ran my program and try to connect to Mosquitto MQTT broker, MQTTClient refused to connect and dies every time. There is absolutely NO COMMUNICATION AT ALL.

With the 2013 MQTT.pas and MQTTReadThread.pas, I am able to connect and communicate successfully but ONLY for anywhere between 1 minute to 5 hours. Then, the MQTTReadThread stops working COMPLETELY, even though my software keeps publishing messages. The only way I can regain Read Communication is for me to shutdown and restart my program. I was hoping the new or updated MQTT and MQTTReadThread will solve my problem, but it is even worse. I would much appreciate it if someone could give me some hints or clues... Currently, I am trying to see why MQTTReadThread mysteriously quits reading the incoming messages. Thanks.

the code has very non-standard formatting (strange string translations, large indents, spaces).
How about making JEDI Code Formating? (lazarus feature)
I can make Pull Request with new formating.

Example formating:

          constructor Create(Hostname: ansistring; Port: integer);
          overload;
          destructor Destroy;
          override;

   // Helper Function - Puts the seperate component together into an Array of Bytes for transmission
        function BuildCommand(FixedHead: Byte; RemainL: TRemainingLength; VariableHead: TBytes;
                              Payload:
                              array of Byte): TBytes; 

After compiling, it will automatically exit after running for a day or two?

Hi,

Been using the mqtt-free-pascal component recently to give my application message queue functionality and also sync with web apps.

But most brokers need a username and password. So I saw it was in the comments as a TODO item so I tried to hack in the functionality.

I commit the change to my own repository and the changeset can be found here:

ludoza/Chee@af9ef37

If I must create a pull request or clean it up a bit before hand. Let me know, and I will try my best.

Thanks for the library!
