Weird behavior setting fifoThreshold

[s4cha]

Hey,
I was encountering issues with imu.settings.fifoThreshold when I realized the high byte is commented out in

LSM6DS3.cpp line 849.

    //Write the data
    writeRegister(LSM6DS3_ACC_GYRO_FIFO_CTRL1, thresholdLByte);
    //writeRegister(LSM6DS3_ACC_GYRO_FIFO_CTRL2, thresholdHByte);  // <--- Is this expected?
    writeRegister(LSM6DS3_ACC_GYRO_FIFO_CTRL3, tempFIFO_CTRL3);
    writeRegister(LSM6DS3_ACC_GYRO_FIFO_CTRL4, tempFIFO_CTRL4);
    writeRegister(LSM6DS3_ACC_GYRO_FIFO_CTRL5, tempFIFO_CTRL5);

Seeed_Arduino_LSM6DS3/LSM6DS3.cpp

Line 849 in b3f118f

//writeRegister(LSM6DS3_ACC_GYRO_FIFO_CTRL2, thresholdHByte);

Is this expected?

Hello, thank you for submitting this issue. I think the line of code you pointed out does have a problem, In order to set the full 16-bit FIFO threshold, the code that writes to the FIFO_CTRL2 register should not be commented out, which limits the maximum valid value of the FIFO threshold to 255. However, to further confirm, can you describe the problem you encountered in detail, and can you post the detailed code and log?
