TXT zu TXT, Kabellose Kommunikation ...

[3rk404]

Hallo liebe community,

Wir hatten die idee, mehrere ft modelle in unserer schule einen gemeinsamen zweck zu geben (Fließbänder, Sortierer, Saug-Arme, ...). Dafür sollten diese variablen (RoboPro) austauschen können. Diese Funktion ist in “Hilfe” erklärt, funktioniert aber nicht, laut den neusten Posts die ich finden konnte.
Die TXT’s sind auf 4.2.4.0 und RoboPro auf V4.2.4.
Leider kann beides nicht ge-updated werden, da die TXTs der schule gehören und die RoboPro version ist nicht mit der neusten kompatibel (die Programme lassen sich nicht mehr öffnen) was ebenfalls im einer schule, die sehr alte beispiel programme verwendet, nicht okay ist.
Meine frage ist, ob die neuste version die Bluetooth Kommunikation ermöglicht, ob es ein Server-programm gibt, welches die TXTs verbindet oder ob die community software sowas ermöglichen würde (RoboPro müsste weiterhin zum programmieren genutzt werden)

Danke schonmal im voraus und einen schönen abend noch ...

The documentation is in English so I keep it this way but you can use Google translate:
(To update in case of problems with the RoboPro update)

See for flashing TXT firmware 4.6.6, 4.7.0 (pre-release) or 4.8.0 (pre-release) from SC-card (all for these firmware's use RoboPro 4.6.6 later):
1) https://github.com/fischertechnik/FT-TX ... om-sd-card
--> Attach Serial USB Converter
(3.3V converter), for example: https://www.adafruit.com/product/284

Remark:
I am not sure if this is already working with firmware 4.2.4.
Otherwise you can contact your supplier or fischertechnik about an update of the firmware.

Thanks for answering ..

So the newest software for the TXT supports bluetooth communication between two or multiple TXT’s? If so, it would be a good reason to convince my teacher, to update all the TXT’s and RoboPro installations ...

Thanks in advance.

For as I know there is no TXT-TXT BT connection defined
But I case you are able to change the fixed BT or USB address of a TXT, you are able to use the Windows system as message router.
You will need to develop this yourself.

With WIFI this is easier. The TXT can get their own IP-address.
So you can for example use Mosquitto MQTT or Web socket or Berkeley socket for the communication.
Embedded Civetweb server can help you.
For this you will need at least 4.4.3. Firmware 4.2.4 is really out of date.

There are several ways to implement it.
With a external WIFI-router or use one TXT as WIFI-router (access-point) and the others as client.
For the last you probably need to adjust some access point settings at UNIX level.

If you need this at RoboPro -level you will need to develop the RoboPro extensions (SLI's) yourself.
======================================================================================
Note about firmware 4.2.4:
I did not try this but this looks like a nice experiment.
With 4.2.4 it could be possible to have one TXT as WIFI access point and use the other as WIFI client..
The client TXT needs to connect to 192.168.8.2 (WIFI)
But you need to work with local C/C++ programs for the functionality.
