MLX90640 returning alternating 0.0 / 222 measurements

Hi guys,

hopefully somebody on here can help me: I’ve got an MLX90640 from here two days ago, which worked well with my ESP32. Not quite sure what happend - but today alle the temperature readings from mlx.getFrame(frame) are 0.0; 222.x; 0.0; 223.x;…

Can I someway reset the camera? Is it broken? I tried slower comunication, lower refresh rates, lower ADC resolution… nothing seem to work.

If anyone has an idea would be really apprechiated!
