Configure GEETECH Iduino Yun Shield

gistfile1.txt

### Problem: Cannot send console messages from arduino console sample: https://www.arduino.cc/en/Tutorial/ConsoleRead

### Config: 

1.- Original Arduino Uno Board
2.- Geetech Iduino Yun Shield Clone
3.- Arduino IDE 1.8.5
4.- Ubuntu 18.04 Linux 64

### Symptom: 
1.- Applied Jumper setting from http://www.geeetech.com/wiki/index.php/Iduino_Yun_Shield#Connect_to_Arduino_Uno
2.- Connected and Condigured Yun shield using Wifi (using web interface: http://arduinoyun.local/)
3.- Can upload sketch using network upload (from Arduino IDE)
3.- Serial monitor says:
Unable to connect: retrying (1)... 
Unable to connect: retrying (2)... 
Unable to connect: retrying (3)... 
Unable to connect: retrying (4)... 
Unable to connect: is the sketch using the bridge?

### Fix: Modify arduino IDE configuration

1.- Download both files (or edit online)

wget https://github.com/dragino/modules/tree/m1aster/hardware/YunShield/sketchbook/hardware/YunShield/avr

2.- Go to folder <arduino_install_folder>/hardware/arduino/avr

cd /home/diego/arduino-1.8.5/hardware/arduino/avr

3.- Edit Board File:

gedit boards.txt

4.- Find the right board parameters (mine was Arduino uno) and paste into boards.txt
