fischertechnik community forum

hi all, I want to ask something. Is there any possible way to connect RoboPro on PC to TXT controller via internet (without Fischertechnik Cloud)?

Because on Fischetechnik Cloud I can't change anything, I want to make project Car with the camera, and control the car via internet (IoT)

Thx for anyone helping

It's not 100% clear what you are asking for. It sounds to me like you want to connect your TXT to your local WLAN (e.g. at home) and then access it using RoboPro from an external network like your workplace or the like. Is this true? Then the following is the answer:

This does work but it's more a matter of configuring your home network correctly rather than the TXT.

So what you need to do is to setup your router at home to forward incoming traffic from the external internet to the TXT. Accodring to https://ft-datenbank.de/binary/6435 the TXT/RoboPro use the TCP ports 65000 and 65001 for communication. So you need to configure the so-called port forwarding on your router to forward all incoming RoboPro traffic on TCP ports 65000 and 65001 to the local IP address of your TXT. Then you'll be able to access the TXT from an external network under the IP address provided by your internet service provider to your router. You can use a tool like https://www.myexternalip.com/ to figure that address out. But this external address changes whenever your DSL connection at home is reestablished and you'll have to make sure you always know that external address. That's where services like dyndns come into play ...

To summarize: This is possible but the setup is not trivial without some fundamental knowledge of the internets inner workings.
