All I need to achieve now is getting the data from that CSV up to the internet, any thoughts on this? Perhaps I could upload the file to an FTP server for cron processing and then delete the file from the Arduino after?
I just send data direct to both the SD and Xively, no reading off SD. The data is the same and at the same interval, but Xively doesn't get the time stamping. The SD is for backup and the files stay there for eventual downloading.
