Bluno + esp8266

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,!
