I work on a SmartHome solution using B4X:
- Android Client is written using B4A
- Server written using B4J it runs on Raspberry Pi
- Node software written using B4J (nodes are Raspis too)

I wrote the communication (client->server, node->server) using B4X Websocket server.
It is ok for testing purpose and for my private use, but when I show to my potential customers they alwas ask me if it's SECURE?
I can't say that since b4X doesn't support wws connections.
Other questions are related to the IOS support, which i plan do work on, but still not sure if the wws connetion will work.....

As far as I see from the documenentation for jWebSocketClient library

The API is identical to the B4A library: http://www.b4x.com/android/forum/threads/websocket-client-library.40221/#content (except of the object name which is WebSocketClient).

but B4A library supports wss (WebSocket Secure connection)

Connect (Url As String)
Tries to connect to the given Url. The Url should start with ws:// or wss://

Could you try wss:// for your applications ?
I worked in the finanance industry and addicted on security very much .
I would be worried if I know that somebody is able to obtain control over my house.

P.S. With help of Erel I have already checked successfully MQTT over SSL.

Good points. Thank you all for the feedback (the thread is of course open for more feedback).

Erel !

Here there is a source code for a java based broker , maybe you can create a b4j version .

Java MQTT lightweight broker: https://github.com/andsel/moquette

How is it connected? HDMI? Any configurations needed or is it plug&play?
