VL53L4CX Issues

Hello Everyone,

We have a custom board that utilizes 10 x VL53L4CX sensors, length of board is about 66cm. For context I am using an NRF54L15 with Zephyr. On bootup they are all configured with a different address and an attempt is made to calibrate the sensors as well. I am using the 

I have been testing for a few weeks now and I am constantly running into initialization issues, all revolving around communication to sensors, especially when I am trying to run through a calibration on the sensor. I have tried different calibration methods, but all result in errors. And if I comment out the calibration I would get a Hardware Failure error after a few reads from the sensor. 

My initialization code flow is as follows: 
Shutdown all sensors -> Boot sensor N -> change I2C address -> Wait Device Booted-> DataInit -> PerformRefSpadManagement-> SetOffsetCorrectionMode(STANDARD)->PerformOffsetZeroDistanceCalibration()-> GetDeviceInfo()->SetTuningParameter(PATCHPOWER2)->SetTUningParameter(MERGETHRESH10000)->SmudgeCorrectionEnable(NONE)-> SetMeasurementTimingBudgetMicroSeconds(100000);

When using VL53LX_PerformOffsetZeroDistanceCalibration() I get the VL53LX_ERROR_OFFSET_CAL_NO_SAMPLE_FAIL error.

Now if I skip the calibration:
Shutdown all sensors -> Boot sensor N -> change I2C address -> Wait Device Booted-> DataInit -> PerformRefSpadManagement-> SetOffsetCorrectionMode(STANDARD)->PerformOffsetZeroDistanceCalibration()-> GetDeviceInfo()->SetTuningParameter(PATCHPOWER2)->SetTUningParameter(MERGETHRESH10000)->SmudgeCorrectionEnable(NONE)-> SetMeasurementTimingBudgetMicroSeconds(100000);

 

I get the following when reading from the sensor:

[00:00:12.202,170] <err> VL53LX: Failed to read
[00:00:12.202,346] <err> VL53LX: [vl53lx1@2A] VL53LX_WaitMeasurementDataReady return error (-5)
[00:00:12.202,885] <err> VL53LX: Failed to write

[00:00:12.454,858] <err> VL53LX: [vl53lx2@2C] VL53LX_WaitMeasurementDataReady return error (-5)
[00:00:12.455,396] <err> VL53LX: Failed to write
[00:00:12.455,722] <err> VL53LX: Failed to write
[00:00:12.455,878] <err> VL53LX: Failed to stop ranging
[00:00:12.656,278] <err> VL53LX: Failed to write
[00:00:12.656,637] <err> VL53LX: Failed to write
[00:00:12.656,794] <err> VL53LX: Failed to start ranging
[00:00:12.707,194] <err> VL53LX: Failed to read

I am trying only 2 sensors but they are both failing to read. If I am lucky, I will sometimes get a 

VL53LX_RANGESTATUS_HARDWARE_FAIL

If I change the calibration to SetOffsetCorrectionMode(PERVCSEL)->PerformOffsetZeroDistanceCalibration(100mm) 

It would enter the calibration routine and hang forever inside waiting for the Measurement Data Ready. Again I would assume that it had something to do with the hardware fail I would randomly see as mentioned above.

 

Any help on the matter would be greatly appreciated.

Best,

Ivaylo
