Hello everyone, I am trying to secure data exchange between my STM32WB55 and an external android app ( with BLE) using the Chachapoly algorithm encryption and decryption example found here: https://www.st.com/en/embedded-software/x-cube-cryptolib.htm...

Hello everyone,so I am using the X-NUCLEO-53L1A1 TOF sensor and I want to detect the height ( Z) of objects that it detects but in the examples I found it only shows information about the objects' range ( distance Y) so my question is : Is there a w...

Hello,I am working on the SimpleRanging example associated with X-NUCLEO-53L1A1 TOF sensor, so I lanched it using the IAR IDE as noted, but I can't read data in the Tera Term ( nothing is shown on the terminla) although I checked the IAR livewatch an...

Hello @John E KVAM and thanks for your answer,actually I did something similar to that and I know it gives me great results but my ultimate goal is to calculate the height of the detected object and not it's distance from the sensor that's why I fir...

Hello @John E KVAM again,I think when I use the method I explained previously the issue is that the height is only affected by the range? so if we remove a portion of the detected object the calculated height would still be the same because there we...

Hello @John E KVAM ,you will find attached the method I am talking about explained in details, so you can understand me better.also this is where I found about the 63 degrees FoV : https://www.st.com/en/embedded-software/stsw-img024.htmlThanks.

Hello @John E KVAM thanks for your answer,I am indeed working with the X-NUCLEO-53L5A1 for that matter, and, knowing that it has a wide 63 ° diagonal FoV, I can multiply tan(31.5) by the range of the detected object to obtain the height Z ( maximum ...

Generate a public_key using Diffie–Hellman or ECDF algorithm from my private_key

Hello, I am trying to implement the HKDF algorithm to generate a secret key, and I found a link containing an example of HKDF implementation ( you will find link below in details) but unfortunately, the code is incomplete and I have a few questions.

X,Y and Z coordinates for X-NUCELO-53L1A1 TOF sensor.

53L1A1 SimpeRanging printf problem

Hello, I am trying to install the VL53L1X GUI on my PC to work on the X-NUCLEO-53L1A1 expansion board, but I keep getting this same error as will you find attached. Any ideas how to solve it ? thanks. and is the VL53L5CX compatible with my 53L1A1?
