There is a new Windows and Mac Video Creator program called Eplaindio that recently became available. You may not think this post has a lot to do with MicroController Electronics, however, read on before you formulate an opinion. Serial.println("Can not connect to WiFi.") Serial.println("Enter Commands Manually.") Serial.println("ESP8266 Module did not respond.") If (Serial1.find("ready")) Serial.println("Module is ready") Here is a sketch showing the Reset function. You can download the Fritzing diagram source here. Fortunately there is a way to ‘RESET’ the ESP8266 from code if this situation occurs. However that is not a programatic solution. To recover you can power off the device and power back on. The ESP8266 is essentially locked up (i.e. Sometimes the ESP8266 will return ‘busy’ when you enter a command. I ran into a common problem with the ESP8266. Now I can add sensors to this circuit and send the information they gather through the ESP8266 to the WEB. Testing the ESP8266 on an Arduino with two hardware serial ports is much easier than my original way. Any response from the ESP8266 will be ‘echoed’ in the serial monitor. Once you upload the sketch to the Arduino, run the serial monitor and the commands you type will be sent to the ESP8266. You only need to change the serial BAUD rate for Serial1 (the ESP8266) from the default of 9600 to 115200.
