Question

Sensor init failed on using VL53L1X ultra low power driver

We have been using the full driver for VL53L1X and would like to try out the new ultra low power driver on our board. Everything works fine with the full driver.

However, we are facing a problem on VL53L1X_ULP_SensorInit() when using the ultra low power driver. It always return VL51L1X_ULP_ERROR_TIMEOUT as VL53L1X_ULP_CheckForDataReady() always return 0. We believe the I2C driver is working properly as it return 0x03 on reading VL53L1X_ULP_FIRMWARE__SYSTEM_STATUS on earlier state of the init routine.

We are using our board with STM32L072 and a VL53L1x. We have been using the full driver and everything works fine.
