See my contribution from: 18 Nov 2022, 10:19. For booting from SD-card, you need firmware 4.4.4. Then you are able to boor 4.7.0 from SD-card. Booting from SD-card will not damage the TXT. Only the bootimage in the TXT memory is not used (including the settings). When you read my 8 Nov 2022, 10:19 p...

I think if you want to help people further, it should be explained: What is the structure of the program and why was it chosen? How did that structure come about? What are the mutual relationships? What are the specific problems arising from the chosen programming language? If new Blocklies are crea...

To train children in how to create a functional computer program, I think it is important as a teacher that they first learn and gain experience in being able to describe the problem properly and based on that description they can design their design for the computer program. Also taking into accoun...

There is no documentation,that is the fun. :D That is also the problem with this software, there is no documentation. Where RoboPro (classic) had a special tab for documentation, the possibility for documentation with RoboPro coding is very limited with only the Blockly elements, which is quite conf...

Under security.
You need to scroll te setting menu.

Have you activated the SSH option in the options menu of the TXT (settings)?
Putty is an SSH connection.
There is also the option to activate boot from SD card.
No Putty is needed to run other firmware from sd card.
A bootable SD card.

Blockly is a text generator and is limited to a limited subset of Python's capabilities. The classic RoboPro (TXT) cannot be compared to Blockly; it is a full-fledged 4th generation language that allows the end user not to deal with low level things of a 3G language such as: Python, C++. RoboPro cla...

The new MQTT blockleys in firmware 3.1.4 are unfortunately not documented. There are even more extensions. Since Nov 2021 I haven't tested much; this because I had already reported some minor problems that prevented me from getting any further. Next week I will restart testing and also the MQTT exte...

Has anybody already loaded into RoboPro coding and try to understand the example Sorting_line_A1 or the HBW? (RoboPro coding, new|Examples|Trainingmodels) And compared this Sorting line program with the sorting line or HBW RoboPro program (ft-factory 9V)? Nice to see that it is now possible to add J...

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. But that was already possible with the TXT with a RoboPro SLI extension element, like I am using with the ft-factory (9V) Th MQ...

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
