ESP8266 Thing and Python serial communications

Development Boards ESP32

I have been trying to use python 2.7 to listen to the ESP8266 Thing. I am using the Arduino programming environment to program the ESP8266. The Arduino IDE debugging terminal receives and displays the information from the Thing fine. When I try to use python to listen to the serial port the Thing stops sending serial data (judging from the LED on the SparkFun Serial Basic Breakout - CH340G).

I tried the same python and Arduino code on an Arduino Uno and it works fine.

What am I doing wrong? I think python may be sending some sort of reset to the ESP and that might be the problem but I really do not know where to go from here.

ESP8266 Code:

 int count = 0;

  void setup() {
    Serial.begin(115200);
  }
  void loop() {
    Serial.println(count, DEC);
     count++;
    delay(1000);
  }

Python Code:

import serial

ser = serial.Serial(port='/dev/ttyACM1', baudrate=115200)

while True:
    print ser.readline()

Python 2.7.12

Thank you.

Just saw a similar problem on the forum (no solution yet).

OK, silly me. I have to remove the jumper tying the GPIO0 pin to the DTR pin.

I hope this helps some one. It was frustrating to me but now it works.
