Im trying to connect bluno v2 (DFR0267) with ESP8266 with this code:

Code: Select all
#include <SoftwareSerial.h>  
SoftwareSerial esp8266(2,3); // make RX Arduino line is pin 2, make TX Arduino line is pin 3.
// This means that you need to connect the TX line from the esp to the Arduino's pin 2
// and the RX line from the esp to the Arduino's pin 3
void setup()
{
Serial.begin(9600);
esp8266.begin(115200); // your esp's baud rate might be different
}
void loop()
{
if(esp8266.available()) // check if the esp is sending a message
{
while(esp8266.available())
{
// The esp has data so display its output to the serial window
char c = esp8266.read(); // read the next character.
Serial.write(c);
}
}
if(Serial.available())
{
// the following delay is required because otherwise the arduino will read the first letter of the command but not the rest
// In other words without the delay if you use AT+RST, for example, the Arduino will read the letter A send it, then read the rest and send it
// but we want to send everything at the same time.
delay(1000);
String command="";
while(Serial.available()) // read the command character by character
{
// read one character
command+=(char)Serial.read();
}
esp8266.println(command); // send the read character to the esp8266
}
}

And on serial monitor there are only some continuously garbage words.
I was trying both esp8266.begin(115200) and esp8266.begin(9600) (baunds).
Maybe whos had the same problem, and maybe know how to solve it? :)

Sorry be late to reply.

https://www.dfrobot.com/wiki/index.php?title=SKU:TEL0092_WiFi_Bee-ESP8266_Wirelss_module It should work as long as you did following the wiki page.

I met a problem that the SoftSerial would have no reaction, but once I reset or re-open the software, it will work.

To your question, I think you missed to set the software's serial monitor's baud rate except setting in the sketch. This step could also be found in the wiki page.

God luck,!
