Good afternoon.
I have an Arduino Uno and a pair of Wemos D1 mini. Arduino Uno works perfectly and the serial too.
When connecting ESP8266 cards, I cannot get the serial to work at any baud rate. I don't get a final "ready" and it doesn't respond to any AT command. The frequency with a more consistent response is 74880, but as I said without a final "ready". I'm desperate. Any help please.
