Yes, in TXT4.0 firmware version 3.1.4 you can do the same in Python or C++. In Node red you also create MQTT clients, which are publishing and subscribing to a MQTT broker.

MQTT broker === services, it takes care of the connection with the WLAN
It is managing subscriptions and publications in general, including QOS.
You have a MQTT client that is using the MQTT broker services.
See: http://www.steves-internet-guide.com/mosquitto-broker/

On the TXT is a Mosquitto MQTT broker available and it is possible to change its configuration file.
Is this also possible on the TXT4.0?
How to stop and start the MQTT Mosquitto broker on the TXT4.0?
How to change the mosquitto.conf in /etc/mosquitto?

However in compare with the TXT, 100ms is very slow for closed control loop applications.
For example, the fischertechnik pulswheel sensor is aiming to 10 ms.
How to combine Rest API with black box control loops created in Blockley?

Thanks, the description by LPE is very old (Windows 8 or 8.1) but there is a new version available.
The actual version is 1.8.2

This are the REST-API? What about the speed? What about the sample rate for close loop controls stability? Where is the official fischertechnik documentation? ================================= Dies sind die REST-API? Was ist mit der Geschwindigkeit? Was ist mit der Abtastrate für die Stabilität der ...

I saw on YouTube that version 1.8.1 would be available. It is not entirely clear who sells this product and who is also the first point of contact. Who sells this? I did find a retail outlet for an old version, 1.3.2. Is there a license for an educational institute? =================================...

Some links are not valid anymore is this thread.

TXT => RoboPro (Classic)
TXT4.0 => RoboPro Coding

I work with the fischertechnik factory in education and there we are using RoboPro with SLI extension elements. I've tried to convert some pieces to RoboPro coding and run into quite a few limitations. RoboPro is much more powerful than the Blockley building blocks. They only provide a limited subse...

No improvement of the integration of end user Python code parts (for example end user defined classes) into the Blockley code pages.
Extension of the functionality like that this was possible with SLI in RoboPro is still not available.

What has been changed?

See here to flash a bootable TXT firmware image to the TXT memory.
(Only for experiance users, you will need a USB to serial interface (3.3V))

This was a long time ago the suggestion from fischertechnik to avoid problems. type error 4.4.0 => 4.4.4 Bootimages is available on the github site. It is also possible to boot the normale fischertechnik TXT firmware from SD-card since 4.2.4. So it is possible to work with different TXT configuratio...

Moin Moin. ich bin seit längerer Zeit wieder voll bei Fischer und vor allem habe ich jetzt Zeit dafür. Bei den TXT Controllern habe ich Probleme. Einer hat die 4.1.6.0, der andere die 4.2.4.0. Beide lassen sich nicht auf die 4.7.0.0 aktualisieren. Wie kann ich es anstellen, das beide aktuell vom Sy...
