I get the same histogram data every time on VL53l3cx

[DMehr.2]

As shown below, the first line is the distance and the rest are histogram data whci I think is same and not correct?

This is the code snippet I am using

  VL53LX_GetAdditionalData(VL53L3A2_DEV_CENTER,pAdditionalData);
                 							for (int j=0;j<24;j++){
                 								printf("%ld,", pAdditionalData->VL53LX_p_006.bin_data[j]);
                 							}
                 							printf("\n");

There is no way to get the same data if in fact you are ranging. For some reason you stopped ranging.

You should call

VL53LX_GetMeasurementDataReady() - this will stall until the data is ready

Check the RangeStatus to insure you got a good range

VL53LX_GetAdditionalData() this will get the histogram data.

VL53LX_ClearInterruptAndStartMeasurement() - to start the next range.

if your VL53LX_GetAdditionalData() continues to return the same data, you have not completed the next range.

I think the problem might lie in me using the VL53L3A2_DEV_CENTER as I think it has the value 0 and not the proprer address which is required? I have trouble finding what to use instead of that. Could you maybe point me in the right direction? I am using the eval board and fr401e board for this.
