4.3 Results interpretation
The data returned by the VL53L4CD can be filtered in order to take into account the measurement status. A new
status is computed for each new measurement. If the sensor is not able to measure a correct distance due to
environment conditions, an invalid status is reported. The following table gives the list of available status.
Table 7. List of available status
Status Gravity Description
0 None Returned distance is valid
1 Warning
Sigma is above the defined threshold (see Section 3.3 Sigma and
signal thresholds)
2 Warning
Signal is below the defined threshold (see Section 3.3 Sigma and
signal thresholds)
3 Error Measured distance is below detection threshold
4 Error Phase out of valid limit
5 Error Hardware fail
6 Warning Phase valid but no wrap around check performed
7 Error Wrapped target, phase does not match
8 Error Processing fail
9 Error Xtalk signal fail
10 Error Interrupt error
11 Error Merged target
12 Error Too low signal
255 Error Other error (e.g boot error)
