Hi,

I am testing out uploading data to pachube using the exmaple on wiki and here is my code snippet.

I think all commands are being returned OK from the ascii code , but i cant find my data “98345” on pachube.com/feeds/49954

Anyhelp is greatly appreciated…

OK i figured out that this issue was with my stream on pachube. I had to recreate the keys and it works now
