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.

Progress indication in % was more then 10 minutes 99% TXT4.0_2 1- Update took 17 min. and was succ...

I notice today that there is a recent update to (PC version 6.1.2).
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...

@fishfriend
See the release notes for 4.7.0:

@Holger Here you will find a lot of information about programming for the TXT: https://github.com/fischertechnik/txt_demo_ROBOPro_SLI https://github.com/fischertechnik/txt_demo_c_online https://github.com/fischertechnik/txt_demo_c_download https://github.com/fischertechnik/txt_training_factory But a...

As far as I understood the TXT with the fischertechnik firmware. The communication in the online mode is based on the principle of the Transfer Area with the associated refresh rate, in addition there are at least two extra Berkely sockets (IP sockets) in use for video and I2C? (is not documented). ...

Maybe the 5 sec online SLI bug (also for I2C valide because these I2C RoboPro elements are SLI functions).

Be aware of the online 5sec SLI bug: I published this bug several years ago. The RoboPro runtime terminates an SLI process if it is idle for 5 seconds or more. A " SLI dummy" KeepAwake function call operation in RoboPro that is repeated within every 5 sec is sufficient as a work around. See also: ht...

@Björn About 5sec SLI bug: I published this bug several years ago. The 5 sec bug is the same as the one with the RoboPro SLI elements. The RoboPro runtime terminates an SLI process if it is idle for 5 seconds or more. The two I2C ROboPro elements on the TXT are implemented as SLI elements. A dummy I...

I probably misunderstood this page:

Very nice.
Thanks for sharing, Huub

Rei's comment also directly relates to the TXT4.0 and the developments in the software. That's why it fits well in this section. Especially when I look at some other topics. Rei started in English, in the reactions that aspect is sometimes missing. The silence around the TXT4.0 firmware and imperfec...

The original Robo Pro brought robot programming at a higher abstraction level closer to the end user and therefore also the young people. RoboPro coding, a text generator for a small subset of Python, brings the elementary aspects of simple imperative programming closer to the end user. RoboPro beau...

Hi Rei I share your hopes for a good continuation of the TXT 4.0 project. It's been pretty quiet since the release of TXT 4.0 firmware 3.1.0 last October. The industrial robots have disappeared from the FT range. With RoboPro coding, which only delivers a subset of Python, programming more complex r...

The IP connection over the internet as well as USB and Bluetooth is also quite unstable in other cases. I reported a year ago that developing remote Python with MS-Visual Studio code is unpleasant because of that instability. After a year there is still no update of the firmware version. ===========...
