I have a VL53L1X ToF sensor working fine (I'm using the VL53L1X-SATEL breakout board). However, when I connect another I2C slave device onto the same bus (its a different type of device and has a different slave address), I see ~60MHz pseudo-sine wave oscillations on both SDA and SCL. Any ideas what might be causing this? I've tried changing the value of I2C pull-ups and also tried putting 33R resistors in series with SDA and SCL, but nothing so far has helped fix the issue.
