Resolved! Vl53L7 ranging result distance not correct with status 6

Hi guys, I'm using vl53l7cx without cover glass.I use the Example_1_ranging_basic in VL53LMZ_ULD_API driver, but i alway receive the result with target_status 6 and the  result's distance_mm seem not correct.Eg i put an target about 300mm in front of...

Resolved! RSVD6 of VL53L5CXV0GC

Resolved! VL53L5CX Calibration after cover glass

Hi, I have two VL53L5CX and use glass to cover them. We can call them A&B.To A, I use the VL53L5CX_XTalkCalibration   function after init. To B, I do nothing.But result of both are close. Does it mean I can cover the glass without calibration?@John E...

VL53L0X inaccurate off-perpendicular?

I'm using the VL35L0X.ino demo code on an Arduino UNO and a clone VL53L0X sensor. I very carefully measured the off-perpendicular distance measurements obtained from the VL53L0X and compared them to actual tape measure measurements. On average there...

Resolved! Long Range TOF

Hello, I want to ask about the maximum range of VL53L1CB, as it says in the table (as seen in attached photo) that it's up to 8m. However, in data sheet or specification just says over 400cm.1) So is the performance should be good at 8m range outdoor...
