SPIKE Prime Hub detected by Bleak but not by Pybricks Web Installer or pybricksdev

[lucamartin8909]

I am unable to install Pybricks on my LEGO SPIKE Prime Hub (45678).

The hub is visible with a BLE scanner (Bleak), but it is not detected by the Pybricks Web Installer or pybricksdev.

Environment

• LEGO SPIKE Prime Hub (45678)
• Windows 11
• Python 3.14.6
• pybricksdev 2.3.2
• Chrome and Edge tested
• Tested on two different Windows PCs

What works

• LEGO Education SPIKE app connects to the hub normally.
• Windows detects the hub over USB.
• Bleak detects the hub.

BLE scan result:

Name:
Spike Hub 2026

Service UUID:
0000fd02-0000-1000-8000-00805f9b34fb

What does not work

Pybricks Web Installer:

• No hub appears in the device list.

pybricksdev:

python -m pybricksdev lwp3 repl

Output:

INFO: scanning...
ERROR: timed out

Additional information

• Bluetooth is enabled on the hub (blue blinking LED).
• The hub is not paired in Windows Bluetooth settings.
• Same behaviour on two different PCs.
• scan.py using Bleak consistently detects the hub, but pybricksdev does not.

Is this a known compatibility issue with recent SPIKE firmware or could this indicate a firmware or device detection problem?

If you purchased this hub recently (Spike Hub 2026), it's possible that this hub uses a newer update method. It's no longer needed to hold or press any buttons.

We've already added support for this over at https://beta.pybricks.com/.

Please give it a try and let us know how it goes. If everything is working well, we will bring these updates to the regular version soon.

We did this upfront ... and were very hopeful
Does not work (yet) - we are trying - BUT thank you for answering

[laurensvalk]

Which step doesn't work? Does it not show your hub when you click the following? Remember to connect via USB.

You can use the same USB cable as with the official app. (You can even test your cable there to make sure, though remember to close the app then so both apps don't try to connect at the same time.)

[lucamartin8909]

ok, I will tell you step by step

[lucamartin8909]

Switch on and off - and closing everything did it - let me double check

[lucamartin8909]

seems to work, thank you

[lucamartin8909]

No, when we go back to the app - and want to connect - it says hib has different internal electronics ... does not support - continue on beta browser ?

[lucamartin8909]

also, it still connects in regular Lego SPike software. Now it is in bootloader modus, we have to remove the batterie and wait - otherwise we see a square and a single small one

[lucamartin8909]

After 6 hours trying - I need to leave for today - another day. Thank you

[lucamartin8909]

The hub never leaves DFU mode after a successful flash. The display permanently shows the bootloader symbol (square with dot).

[laurensvalk]

The square with the dot means it's complete. That's how Pybricks looks. 😃

Now you can make programs. You can choose Bluetooth or USB. Up to you.

The dot is the program indicator. You can move it to the left and right to choose a different slot.

Thank you Lauren, but no- it says "This hub has internal electronics and requires a different firmware. pybricks does not support this yet. we are working on it." I am not sure if today or tomorrow I will continue to work on it, but I am not confident. In any case I thank lots for your responsiveness and help
