after connecting to server I use this sequence to post data to url using esp8266 wifi module String postRequest = String("POST "); postRequest = postRequest + uri + " HTTP/1.1\r\n" + "Host: " + server + "\r\n" + "Content-Type: application/json\r\n"+ "Content-Length: " + 50 + "\r\n" + "\r\n"+data ; delay(1000); Serial.println("Request Sent:"); Serial.println(postRequest); delay(1000); Serial.println("Data Sent:"); delay(1000); ESP826.print("AT+CIPSEND=50\r\n"); delay(1000); while(ESP826.available()) { Serial.write(ESP826.read());//Forward what Software Serial received to Serial Port } delay(1000); Serial.println("Sending.."); delay(1000); ESP826.print(postRequest); delay(2000); while(ESP826.available()) { Serial.write(ESP826.read());//Forward what Software Serial received to Serial Port } delay(2000); I got no response, anyone knows what is the wrong about this?!
