Quite strange...the script worked only one time....next tryes did not update data but no error at all...any idea?
Please note that date('Hmi') is incorrect. This is hours, month, seconds. It should be date('His') for hours, minutes, seconds.
Just used your code (modified for my needs) to send my WX station data to the APRS server. Thanks for posting this for other to use. I'll add a link to my code once it's ready to publish.
