problem with the arduino nano IOT 33

[cooldog14]

Hi, using fifoexample, and adapting it to the proper pin (LSM6DS3 myIMU(I2C_MODE, 0x6A);).
I don´t have an output for the fifo, it gets stuck at :
while ((myIMU.fifoGetStatus() & 0x8000) == 0) {};
When trying to debut it and printing fifogetstatus, it prints 0's. I don't understand why it doesn't go to the next loop :
while ((myIMU.fifoGetStatus() & 0x1000) == 0) {(...)}
It's been couple days since I'm stuck on it, any help is appreciated.

My guess is that the address are not the same between the library and the arduino nano IOT 33 but I can´t figure out which address I'm supposed to use...
