Android Question How can I build my MQTT server ?

[Adamdam]

Dear all,

Can I build MQTT server ?
i.e. can I find the "MQTT server" code ? and so, install it in local server or in any hosting server, and so, can I add/modify this code .
I know and even used some of them, I use one is free for 5 clients and then I must purchase for more client.

I need to build my own MQTT server, and host it in my server and late modify it to make more function.
There is any free MQTT server code ?

Thanks in advance
Best regards

If you mean MQTT broker, then take a look here: https://www.b4x.com/android/forum/threads/mqttbroker.61548/
There's also this one https://emqtt.io/ - free and not too difficult to configure.
