Please, use PXn instead of pin numbering when higher than 15 (arduino header D0-D15).

Time Of Flight.
Perhaps I need to rename the demo file. I can use BTLE_sensors_demo.ino as the Time Of Flight is "just" a sensor...
| This sketch provides a default demo to be used on STMicroelectronics Discovery L475VG IoT board. | ||
| It will use several components of the board : | ||
| * Low energy Bluetooth (SPBTLE_RF) | ||
| * temperature and pressure sensor (LPS22HB) |

use upper case or low case in a consistent way for all lines

you can => you need to download BlueNRG application from playstore

FIrst need to compile and download the example to the STM32 board right ?
No other action on the board before you can find the device in the application ?

yes, need to compile and download... of course ;)
No other action needed on the board. (Except move in front of the vl53l0x sensor to move the cube.)

just would be good to mention it to know what needs to be started first

I don't think 42 / 43 /44 values are really useful

explain this hard coded value of 20

just used to see an effect on the cube. On each swipe detected, we will perform 20 updates of the cube position.

I understand, but would be worth a comment in the code to explain what it does and what happens if user changes it

Arbitrary value to move the cube. Same as "official" BTLE example

again worth a comment .. I think if I ask questions, maybe other users will as well

I understand the rational but can't we have as well a short description with picture in the example forlder of examples/STM32L475VG-DISCOVERY-IOT ?

I just understood tof means Time of Flight maybe put it here or in the example. Time of Flight (tof)
Or rename to BTLE_sensors_TimeofFligth_demo.ino
