Hi!  
I’m trying to create a basic cube visualisation of the LSM6DS3 on the Arduino 33 IoT in p5js using ble.js-

But I have to say the data I receive is totally random.

This is the Arduino code

This is the P5js

I excluded all the readings, in order to have just one, but the readings on the p5 side are super noisy

Will come back on this tomorrow morning, hope to find some help.

Hi!  
I solved the issue (and several other after).  
The main problem in that moment was that the float was read as two numbers (I think)

What I did is pass everything (yaw roll and pitch) in an array.

Here is a working pair of codes, passing the IMU service.

Enjoy!
