Signal threshold not working as expected?

I'm using a VL53L1X ToF sensor to measure distance with the Ultra Lite driver. I've lowered the signal threshold to 400 because that value seems to cover most valid measurements. When I read the current signal value using GetSignalRate(). When my sig...

Resolved! vl53l5cx_set_ranging_frequency_hz and TOF sensors

The datasheet says the maximum ranging frequency's for VL53L5CXV0GC/1 are 60Hz at 4x4 15Hz at 8x8But the firmware allows for example perfectly 100Hz at 4x4 by setting this value with vl53l5cx_set_ranging_frequency_hz().I also can see the sensor is re...
