Xojo Raspberry Socket

Targets Raspberry Pi
1

Hello,
Has anybody experience with sockets UDP or TCP? Which one is better to use with Raspberry? Or any examples?
I want to run my Xojo App on my Laptop and control some sensors which are connected to the Raspberry.

Sockets should just work nice.
Any problems you see?

except maybe a firewall blocking you.

3

TCP? No I’ve just never worked with sockets.

For an easy implementation, and if you are going to use Xojo on both ends, use the EasyTCPSocket class. Internally uses a TCP connection.

Thanks. I’m not using Xojo on both sides. It’s planned to use Xojo only on my Windows Laptop and on the other side on the Raspberry a Python script.

Well, then you cant use the EasyTCPSocket. To use a TCP conection you have to define your own protocol.

Or if you have more time to learn some new things, what I do in this cases is to use MQTT

What is MQTT? Is this something that can be used with Xojo?

https://mqtt.org/

Is there a Xojo MQTT class or library available?
In the meantime i found a websocket class for Xojo.

CURL may have MQTT support, so you could use MBS Xojo CURL Plugin maybe.
