Salve a tutti, ho collegato esp8266 secondo cio’ che c’è scritto nel codice che ho scaricato da internet, mettendo ovviamente nome della rete e password che ora ho cancellato (non capisco perchè mi chiede due volte SSID e PASSWORD), mi si accende un solo led sul modulo wifii e non vedo lampeggiare l’altro, poi ho impostato il Baud a 19200 ed entrambi (NL e CR) e quando apro il monitor seriale mi dice:
AT + RST
module have no response
Begin error
Init error.
qualcuno potrebbe aiutarmi?
Grazie in anticipo
/*
ESP8266 library
Connection:
When you use it with UNO board, the connection should be like these:
ESP8266_TX->RX(D10)
ESP8266_RX->TX(D11)
ESP8266_CH_PD->3.3V
ESP8266_VCC->3.3V
ESP8266_GND->GND
When you want to output the debug information, please use DebugSerial. For example,
DebugSerial.println("hello");
Note: The size of message from ESP8266 is too big for arduino sometimes, so the library can't receive the whole buffer because
the size of the hardware serial buffer which is defined in HardwareSerial.h is too small.
Open the file from \arduino\hardware\arduino\avr\cores\arduino\HardwareSerial.h.
See the follow line in the HardwareSerial.h file.
#define SERIAL_BUFFER_SIZE 64
The default size of the buffer is 64. Change it into a bigger number, like 256 or more.
