HI

Have just compiled and checked example 2 to be sure. All works fine.

Do you have pull-up resistors on both SCL and SDA to 3V3? Do you power the SPS30 with 5V external ? the xxx behind the serial number did you add those manual ?

regards, Paul

Hi Paul,

Yes the pullups are there 10K to 3v3. I use the VIN pin on the ESP8266 which is 5V (from usb), my USB port can supply 3A. I checked with a multimeter, just also tried external 5v, no change in behavior. And yes i added the xxx (although it is not sensitive information).

It is clear the connection is working as you get the serial number and can read the results. I have just connected the ESP8266 and did the same test example2. and added some comments in between. My SPS30 answers to the request: I2C Sending: 0x80 0x04, where yours is not.

Try this : remove both power source, count to 10 and reconnect (5V first). Maybe the SPS30 is in state of flux. What happens if you try to set the autocleaning ?

regards, Paul
