it's hidden very well, under "device-guide" here's the link to the german page https://www.lego.com/de-de/service/device-guide/mindstorms-robot-inventor/ or for netherlands https://www.lego.com/nl-nl/service/device-guide/mindstorms-robot-inventor/

yes, it has.

True. But where is the problem with that? Therefore the RI Software offers an area to show variable values and sensor values togethet with your program, which is much more useful. I know what breakpoints are, but don't know why this discussion comes up with EV3 and RI. Did you ever set up breakpoints with a python-program running in different threads? As far as I remember you have to start pbc instead of your program. It's not that simple. As you say: it's not common with EV3. There are some workarounds, like inserting a loop to expose values etc while looping. But setting breakpoints isn't simple in general, because they often stop your program at a certain point, but don't infect other threads running. Yes, it has to be connected. As with the EV3, because it's nearly impossible to read debugging values on the screen of an EV3 on a moving(!) robot . And you never see your values and the sensors on one screen, you have to switch the display, while machine is moving around.... For huge projects you should program a dashboard or something like that, cause picking Infos for 2-4 small screens isn't funny. Anyway: there are no "breakpoints" in the meaning , that this is functionality of the IDE, neither with EV3 nor with RI. The only thing that's missing with RI is to write "messages" to a screen, cause there is none.

I see. You can add stop or loop/wait everywhere you want to to examine what happens here and in which state the machine is . Like with the EV3. Or what do your mean with "breakpoints" with EV3? But obviosly you're looking for something different, so it would be good if someone else could give a precice answer. And why this in conjunction with the BT, I didn't catch yet. I'm still thinking about RI instead of my 4 EV3, perhaps that would give me a hint.

No, I'm asking why this has something to do with bluetooth. As far as I know you can see the values of motors and sensors, check status of variables and so on. Am I wrong?

Yes, in both EV3 sets the cables are included. But they differ in what's included: the 31313 has a infrared sensor instead of the ultrasonic, but comes with a remote control(IR)

Very nice!

That's the problem. If you cant't describe what it should do nobody can tell what you need. As an example: if you want to build a car your need two motors, one for steering, on for drive. How many motors do you need? I have no Idea. In Summary: you can use EV3, RobotInventor or PoweredUp. But they differ in how to program and what you need besides them.

I don't have the RI, but looking at the software this is wrong. Why don't you install the SW to check out? But you don't have any onld huge programs? Why? The day when the Robot Inventor was realeased....

yes, because you have the \n in "write" and and automatic \n in "print" Just found that to remove the \n while "read" https://stackoverflow.com/questions/15233340/getting-rid-of-n-when-using-readlines Or just read the complete file without loop....... HTH

What happens if you add the \n only in line 93 ? (and not in line 85, the print command)?

Hi, sounds like a nice project! As far as I know the python "write" which you use does not add a "new line" (whereas your print does!) Try file1.write("your value \n")

I cannot imagine that. Yes, your Smartdevice in conjuntion with the Lego boost App and the PoweredUp Boost. Anything else but sound.... Light, movement, certain colors (nearby), turning or pressing knobs, also from remote...(via IR or BT) This works with EV3, Robot Inventor or PoweredUp

There is no microphone in EV3. And how should some software detect the "certain" music?

Hi, if thats all that difficult end expensive you could redesign your product? Only the battery in your box that is one brick less in height, no electronics at all. Below the outputs of the hub (which means on top of your product) a small common connector from the RC sector. So the charging electronic is outside the modell. Cheap, small, easy to handle.

Might work, might not be working anymore with a newer FW. Nobody knows.

You could perhaps(!!!) use the motors on PoweredUp hubs, that's all I think. That all depends on the FW in the Hubs.

No. As I wrote: on Android devices

With an android device this is possible, you find them in a seperate folder.

Hi, python is available fo both systems. I find python much easier than the Scratch version. Help ist much better. Yes Robot inventor can be controlled by SmartDevice or game controller (without BC2).

Hi, good news. Where did you read "injection molded"?

Hi all, just wanted to do some tests, but the FW-download-Button doesn't react any more? Chrome has updated in the last weeks to Version 88.0.4292.2 (Offizieller Build) dev (64-Bit) Might this not be useful? FTP is obviosly removed from Version 86 on, might that be the reason?

Hi Conelius, thanks a lot!
