I'm trying to connect a Sensirion sps30 with a ESP8266 on wifi. I used Arduino to program the ESP8266, but this is the first time I'm doing this. I found a filled out sketch and I only had to put in the SSID and password. I did that and the sensor now does a couple of measurements and then tries to connect to the wifi. After that it just tries to connect, but nothing happens. I used a guide from GLOBE.nl for the set-up. I can't figure out what I'm doing wrong. Any ideas?
I tried the Adafruit website and follow the steps, but nothing changed. I've tried finding a YouTube video, but that didn't help either.
