Ahhh! Thanks, I'l give it a try.

Sending single commands you can easily use another characteristic than linear....

It will be fixed by a firmware upgrade, but the typical Duplo buyer doesn't connect to WLAN via App..... The poblem isn't sensor, I assume it's the combination of Distance and RGB, which has to be a bit better adjusted. So the change a 5 to a 7 somewere. That's why they say it will be in store again - in Summer!

I'm searching for 10875 in German S@H - no result displayed (tracks and bridge are shown) https://shop.lego.com/de-DE/search?q=10875 on US-Site: out of stock Got my information from Service, and clients describe behaviour in their comments

I do the ramp by single steps too (raspberry PI, python)

Hi, very interesting. First: you got a complete new Train Hub, or is there FW as a file and a method to load it? Second: There seems to be no final version that works, this is why the set is not sold any more (problem: when climbing the bridge "green" is detected and train changes direction) FW of Hub No.4: Strange as well. I have two here, both showing version 03 01. But one reports as "Hub No. 4", the other one as "Smart Hub". Spooky.

just found: char-write-req 000b 04000201 for handheld char-write-req 000e 04000201 for Smart Hub

Not really char-write-req xxxx 04000201 , the value is given (04000201), but xxxx is the handle. Which one?

I'm not sure if the response correspond with my little video. But of course, everybody his or her own ideas how it should werk, as for me I got neither a layout nor trains I just wanted to show how simple it is to connect the components by something that acts as a "server", but might be an very small microcontoller without monitor or keyboard or an App designed for that. Why? The potential of PoweredUp is much higher than you can achieve with the Handheld. And with the first sensor in your arrangement you need such an instance.

hi, thanks. yes, got different examples using GATT. I'll have a closer look at those. The idea is to read the buttons of the handheld. + accelerates until you release the button - descending until you release the button And my programm does, if it doesnt fail for any reasons....

Yes, that's what I did with SBrick. just wrote a small routine to test, works fine, but only sending commands But how to send i.E. "000f" "0100" and get the output returned?

Hm. Now it works....same Hub, same program. Difference: I had removed the Dongle, and I resetted hci. Spooky. But thanks for your help!

?? I use gatttool -I as a background process and then send the commands But I fear that's not what you wanted to know.....

Hi, good idea! Logilink BT0015 or ASUS USB-BT400 Same with both Is the a method to clear something?

Hi, I'm just working on my small python-Script and I'm facing a stanage behavior of the PoweredUp-Hubs according to the documentation. I am sending commands every 0.2 sec to change speed. Works fine. But after app. 100 commands motor runs continuosly with last speed. Commands are sent, but not executed any more. This is the command: char-write-cmd 0x0e 0a00810016000xx0000, xx replaced by speed Any ideas?
