Not working on Bluetooth UBlox (v5.17.87)

Hi @jagheterfredrik,

Information:
Windows 11, Python3.11

I wanted to use your solution but encountered the following error:

c:\Users\X\Downloads\wallbox-pwn-main>python wallbox-pwn.py
Please choose Wallbox:
0) WBXXXXXXX (6C:1D:EB:XX:XX:XX)

Identified Bluetooth chip: UBlox
Traceback (most recent call last):

OSError: [WinError -2140864497] The attribute requires encryption before it can be read or written

So I made a small adjustment to your code on line 25:
BluetoothDevice("UBlox", False, "2456e1b9... to BluetoothDevice("UBlox", True, "2456e1b9...

After this adjustment, everything worked as expected and thanks to you, my Wallbox is now rooted!

That's great! If you don't mind could you provide some more info on your Wallbox: model, country and approximate date of purchase?

[Florissilfhout]

Sure!
Model: Wallbox Pulsar Plus
Country: Netherlands
Purchase Date: 11 feb 2024
Originally Installed FW: v5.17.87 (Restoring resulted in the same FW)
Serialnumber: 1088***

By now, I've updated to v6.1.19 and I can confirm root access is still present including the MQTT bridge.
