Hi all,
I previously posted this on the pachube forum, no answer , so I copy it there, many thanks all for your help ! 
I'm trying to connect my Arduino UNO to Pachube and send my datas (https://pachube.com/feeds/53223)
My archi :
- Arduino UNO
- RN XV Wifi board (http://rovingnetworks.com/resources/download/16/RN_XV)
- XBEE board Arduino XBee Shield (http://www.arduino.cc/en/Main/ArduinoXbeeShield)
- NTC Temperature Sensor (http://www.cooking-hacks.com/skin/frontend/default/cooking/pdf/159-282-86001.pdf)
- Breadboard
The sensor is connected using this tuto : http://webzone.k3.mah.se/projects/arduino-workshop/projects/arduino_meets_processing/instructions/ntc.html
Due to the mounting of the XBEE shield on the UNO, the "analog Pin 2" coming from the breadboard is connected to it directly
RN XV is plug to the XBEE shield, I load the sketch "WiFly pachube Client" (https://github.com/jcrouchley/WiFly-Shield/tree/master/src/WiFly/examples), and modify it with the right PIN config : pinMode(A2,INPUT) and credentials file to right "passphrase" an "SSID"
So, RNXV is OK, Wifi is connected, can ping the outside world, see below to Pachube
<2.30> ping 216.52.233.122
ping 216.52.233.122
Ping try 216.52.233.122
<2.30> 64 bytes from 216.52.233.122: seq=1 ttl=48 time=203.58 ms
64 bytes from 216.52.233.122: seq=2 ttl=48 time=186.28 ms
I tried to follow a training file given by Roving Networks, that give me the config to upload datas on their website and seems to work. But this test is only for the RN XV itself, and doesn't validate the Arduino and the sketche.
I have the feeling that the Arduino doesn't manage the Rn XV board...
And I can't see anything on my pachube feed ! only "Frozed" because no incoming datas !
(my RN XV and Pachube sketche are attached)
