Resolved! pb with code pin BLE for windows 10 connexion

since last mounth, i cannot connect anymore to my sensor (TILE.BOX) by ble with windows 10 because the code are automaticaly generated. I suspect last update windows don't let me write the std code (123456). So did you know the issue? do you have con...

Resolved! How to calculate bin frequency after FFT?

The ODR of vibration sensor iis3dwb is 26667 Hz. If I set 2048 of FFT size, is the below calculation correct? Or we need to use the bandwidth 6 kHz to calculate the bin frequency. Please advise. Thanks!0:  0 * 26667 / 2048 =    0.0 Hz 1:  1 * 26667 /...
