Question

Does the VL53L5CX need to download firmware every time?

In vl53l5cx_init, the sensor sends the `VL53L5CX_FIRMWARE` data to the sensor. This means the main application MCU needs to store the ~80kB+ in its data. Can this be modified so the firmware is downloaded only a single time, so there is less memory overhead in the MCU?

Hello DBouc.1,

The VL53L5CX is a RAM-based sensor, so every time that you power off the sensor the memory is cleared. There is no way to store the firmware permanently inside the chip.
