Plan A:
Hardware mod of Yun.

Plan B:  
Put shield into Uno, connect Uno via UART to Yun.

It seems that the  AQE shield is not correctly powered with the 5v 500ma µ-usb power source connected to the Yun. The shield's power/info led flash once and no more. (tested N times of course).

The reason it is not working is here:

The Shield has a power connector ( 9 v ) maybe i could power it  via this one, and use it to power the Yun . Is this dangerous for the Yun ?

The power connector is direct feed VIN for 7-15V, and Yun only support 5V.  It will kill the Yun. No go here.

Plan A: Enable ipv6 at OS

http://wiki.openwrt.org/doc/howto/ipv6

Plan B: Recompile your own gpsd with disable-ipv6

Plan C: Ignore complaining about IPv6.

Plotly seems to be free and they have a python api that you can call from the linux side on the Yun to upload data that in my case is stored on the SD card.

Nice.

nano /etc/config/gpsd

Code:
config gpsd core
    option device    "/dev/ttyUSB0"
    option port    "2947"
    option listen_globally    "false"
    option enabled    "true"

make sure  option device    "/dev/ttyUSB0" match with your port.

1. Use fresh OS/software.

/usr/bin/reset-to-factory-anyway
reboot
nano /usr/bin/run-avrdude
Change the efuse value from FB to CB

/usr/bin/run-avrdude /etc/arduino/Caterina-Yun.hex

2. Chang power supply, make 5.0 V close to 5.0 V say ~4.8 V.

3. Use External Programmer.

Exit while loop once done. Add break.
Code:
Serial.println(result); // print the number as well
break;

GP21 default is low, only high while use as internal programmer.

Code:
#!/bin/sh

echo 1 > /sys/class/gpio/gpio21/value

If I were you, I will be waiting official answer.
