auto-clean on esp8266 not working about sps30

[paulvha]

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 SPS30-Example2: Basic reading + clean. press <enter> to start Trying to connect I2C Sending: 0xD0 0x33 I2C Received: 0x33 0x36 0x31 0x44 0x34 0x46 0x44 0x33 0x41 0x41 0x39 0x34 0x31 0x41 0x37 0x36 0x00 0x00 length: 18 PROBE = SAME AS ASKING SERIAL NUMBER Detected SPS30.

As discussed by email, add this to the sps30.cpp file on line 1144 ofter I2C_Setpointer() function.
