Only getting three quaternions

[FrederikPetri]

Hi @aero-man

First of all thanks for sharing this!

When I run your script I only get timestamp + three quaternion values.

In Xsens DOT BLE Specifications I can see that Orientation (Quaternion) should be type 5. And when I change ENABLE_MESSAGE = b"\x01\x01\x06 to ENABLE_MESSAGE = b"\x01\x01\x05 I receive 4 variables. Can you confirm this is correct?

Hi Frederik,

I didn't realize anybody was following this. Thanks for your patience. This was an issue that I was working through with Xsens themselves here: xsens/xsens_dot_server#11

I haven't looked at Xsens or this repo in several months. Not sure if the issue I linked to was fixed or not unfortunately.

Hello, I'm sorry, I know this is not the correct place to write my question, but is a lame question. Is this code just for Mac?
I have a window machine, and I tried to install bluepy but I get an error. And by the bluepy doc, I understand that is just available for Mac.
Thank you for making this available.

Hi @Kris5GJ. Yeah, Bluepy is only for Mac. If you're working with Xsens sensors with Python and Windows, I would look at the following options:

• Bleak, a Bluetooth LE library for Python that works on all operating systems
• PyBluez, another library that supposedly works on Windows, but that I haven't used
• Moving to Python 3.9, which apparently has Bluetooth on Windows. I haven't tried this personally either.
• PyWarble, another BLE library that supposedly works on Linux and Windows 10 and is maintained by MbientLab

The right wat to ask this would be to open a brand new issue that says, "Hey this code sucks and doesn't work on Windows!" Jk jk. For real, a new issue would be the way to go.
