I'm trying to connect Sensirion particulate matter sensor(sps30) with the XDK by providing external power source to sps30. But I'm unable to recieve the data. I tried using the example provided in workbench but unable to recieve any signal. I'm using level shifters to convert 5v signal (from sps30) to 3v signal (for XDK) and the pin connections are PB11, PB12 pins on XDK gateway for I2C and PB9, PB10 for UART. I have contacted iot@legic.com but there is no reply. Can anyone provide me some support.
