I bought the Cactus Micro Rev2, and everything seems to work except the WiFi chip.
I can’t control the chip via AT commands and when I try to connect to WiFi I can never connect.
I’ve tried running the programmer sketch, but when I input “AT” or any other command, I get no output.
Could you clarify how can I exactly work with the ESP8266? My project depends on WiFi and I don’t think my board is defective.
