VL53L4CD clear interrupt does not clear the interrupt

DrD00m · ‎2024-04-29

When calling to clear the interrupt of the sensor I wait for the pin to go HIGH again but it never happens.
I follow this flow:

set i2c address
set low power config
set signal threshold to 5000
set sigma threshold to 20
set intermeasurment ms to 100 and the timing budget to 80
set interrupt threshold to be 1300 and only trigger when below this value
start ranging

The sensor immediately triggers an interrupt and clearing it does not clear it. It stays low. The interrupt pin has a 10k pull-up.
