Also one can use 1001ms delay instead of first 0% step. There is info about it in that GitHub issue.

Hello,

i have got a question about brickcontroller2 (3.1) and buwizz3.0: how can i get the buwizz speed (low,normal, high, ludricious) button in my profil?

With buwizz2.0 it appears automatically. 
 

Cheers, Friedl

buwizz 3.0 doesnt actually use slow normal high or ludicrous mode. its always in the equivalent of ludicrous

Thank you very much! 😊

I wonder if anybody had issues with BrickController 2 (on Android) where it does not stop the motor after releasing the joystick (with PU hub). It does that quite frequently for me nowadays, which today resulted in my model slowly moving while I did not pay full attention, flipping down a slope, and then tripping over a ledge and dropping from 5 meters high, to finally break into pieces in the middle of a bush.. It was a painful experience to collect the parts and put it all together (though only lost/broke a few parts).

@imurvai, anything to do about that?

could it be your controller is old? or latency between controller and phone and phone to model?
sometimes i get high latency for short periods of time, though i am using buwizz 3 usually, i think its just due to whats involved with connecting 3 devices.

you could try a controller tester to see if the controller is outputting signals when it ought not to be

I don't think its old, it's an Xbox Series controller. It's definitely not latency, it does not stop indefinitely. And I don't remember having this issue before, it just does it recently.. 

Hello all, It is my first time here. I created a nice 4x4 moc and wanted to use a PU L motor as a servo with BuWizz 3.0. I am unsure if it was discussed before, but I will look at the thread later. Just in case someone has more info on hand, please assist. 

 

Everything connects, but when I try to select Servo for the PU L motor, there is no calibration; it is grayed out. I have attached images of what I can see.

 

Thank you for the support

Automatic servo calibration with Buwizz 3 unit is not supported (it was said it would be supported later, but it never arrived). So what you can do is build your model so that the absolute zero position of the motor is at least near the centered position, and then you can manually use the base angle to precisely center it, and the max angle to adjust for its max range of motion. Finding the absolute zero position of the L motor is tricky as it is not marked. The easiest would be to hook a bare motor (not yet built into a model) up to a Buwizz unit, make a simple Buwizz profile for it, start it, and let it return to its zero position upon startup. Then you build it into your model without rotating it significantly. Or if you have it built in, you may need to remove a pinion gear and adjust it if it's not at the zero position.

The servo calibration is available on Android phones, but it doesn't work nearly as good as Buwizz app itself. Brickcontroller 2 would be perfect if it had the better steering calibration and a version of Buwizz's own tracked steer module.

I agree, a tracked steer function like buwizz app would be fantastic. For me steering calibration in buwizz app is buggy and rarely works, but always works in BC2. The most important thing is setting the base angle accurately, in my experience.
Not sure how a tracked steer module would be implemented, maybe in the same way as buwizz app where you set it up then assign the output to the mixer thing.

BC2 has helped me a lot, so thanks Imurvai!

Hi, yes, unfortunately the servo calibration is only working on Android yet - my ios dev environment went down and I haven't had time to fix it :(. Also my Buwizz 3 has stopped working (I left it in my drawer for a couple of months and now I can't charge it up), so not sure when I can fix it.

Well, you could take it apart and reconnect the battery. It might help...

I tried that but didn't help. Do I need to leave it disconnected for some time?

I had the same problem (also left it alone for too long) and disconnecting and reconnecting didn't help either. In the end I bought a new battery from buwizz (they sell it on their website for quite a reasonable price) now it works again

Did you try charging it for a long time? Sometimes it needs a really long time, like a whole day on charger to wake up..

or a "dumb" charger, usb a on one end, might help.

Thank you very much for the reply, This helped and it works fairly good, doesn't have a good center back but it works for what I need it to do,

If it is only a short time, find a 5V charger and leave it on charge overnight. If it doesn't switch on, you will need a new battery. Luckily, my unit was under warranty, so they sent me a new one. But thank you for this amazing app. I know how hard it is to set time on personal projects. If you have a PayPal support link, maybe share it so we as a community can contribute. Thank you again

I had this as well yesterday, but with PU hub I assume you mean the small one used in City sets? Perhaps it's related to something else I found yesterday.

Whenever I wanted to start up my model (car with drive and steer), the steering would always go to the left at start up of the MOC profile in brickcontroller 2 and stay there. Every single time. I could fix it by pressing reset or recalibrating the servo in the app, but that would only fix the issue until the next time I turned on the model. At times it would get stuck (similar to what you were having) in one direction during play as well, which you could stop by flipping the joystick the other way, but until then you could hear the motor beeping that it wanted to keep going.

 

I did some testing and I think I found the cause of the issue for at least the steering going left and staying there on start up. I had the steering motor mounted on port B of the City hub, which was fine sometimes when that was the only thing I plugged in, but it would pretty much always fail once a motor was hooked to port A as well. I tested this with 2 L-motors (the one in the model that had the problem and another unused one). I also tried 3 City hubs with these 2 motors, all showed the same pattern. I tried to do one of those hubs with old hub firmware, but while brickcontroller found the hub I could not control any outputs, so I updated that hub as well (all ran latest Lego hub firmware). Once I put the steering motor on port A and the drive on port B I had no problem. I guess either in the hub firmware or in the brickcontroller app something messes with port B signal. Now I wonder Gyenesvi, if the motor that caused your problem was hooked up to port B as well?

 

If this bug in either the Lego hub firmware or brickcontroller app was already mentioned, I apologise. I hope it's something @imurvai can shed some light on.

 

edit: doesn't look like I fixed it, see here.

Hmm, interesting findings, though I was using the 4-port technic hub, I have no city hub at hand. And I don't quite remember which port it was, but I think I had 2 drive (L) motors on A+B, and one steering (L) motor on C or D.

Is there any possible way to run this on a raspberry pi?

So, I have a slight problem with the app and was wondering if it affects anyone else or if there's a solution I'm not aware of.

When using a technic hub, I can run set a port to a servo motor type and then set the servo range to up to 180°. This is perfect for me. The calibration doesnt go as far as it should for proper calibration, but that actually isnt a problem because of the ability to adjust the base angle. The issue I have is that I cannot set the servo range when using a Buwizz 3.0 unit.

Im using the Buwizz units port 1, and I updated the firmware on my buwizz units a few months ago. My phone is a samsung S23 FE running android 14. Im using the 7th jan 2023 update version of the app (latest).

If I should provide more information, please let me know!

The fix in my previous post is wrong. I thought I fixed it, but turns out I didn't. I used the same hub to install the Pybricks firmware on it to try and play around with that a bit and then restore the normal Lego firmware. That all went fine, but now the problem of the steering going left on startup of the program returned, while the ports were in the "I fixed it" position. So I fixed nothing Steering motor on port A or B, it still messes up. One thing I did find out though. When everything is ready to go and I press "play" in the brickcontroller app and the steering turns left as expected, but when I press the back button of my phone and then press "play" again in the brickcontroller app, the steering goes from the left to the center and everything works fine. I am going to assume this was always an option and I jumped to gun by going automatically to recalibrate the steering instead of trying this. It's  weird bug from somewhere, but only having to press "play" twice to make it work normally is alot better than thinking I needed to recalibrate everytime I turned on the hub.

Hi, i recently bought a moc on aliexpress, and it had 3 controlling units of the mark “xp block” in it. The units are similar to buwizz 2.0 bricks, but the app control has much fewer options as brickcontroller2. I tried to couple de bricks to the brickcontroller app, bit it is not compatible. I was wondering if it is possible to make brickcontroller2 compatible the xp block so i can operate the moc with a controller.
