I’m using the SparkFun Mini Spectral UV Sensor with a ESP32 C3 Super Mini board connected to the normal I2C pins. Sensor power light comes on and when I use your Arduino library with my sketch everything says it is successfully connecting. But when i read UVA and UVB they always have the same values…

AS7331 always returns the same values

And yes, the power LED is lit on the Mini Spectral UV Sensor board

AS7331 returns same values each time
