Hi All,
I Have a CR300 cell215 logger with a Garmin GPS 16X HVS and a water-quality sonde on SDI12. I am trying to send the data from sonde data table to a https server. I can see the first attempt by the logger after compiling the program is successful and it's connecting with the server. But the subsequent requests are failing and I am receiving the below error. i believe the connection was never closed after the first attempt. what should I add to send data to the server at 15min intervals and append to the same file.? any suggestions and help would be highly appreciated. Thanks

I suggest trying the following,
1) Clearing http_put_response and http_header before each call of HTTPPost.
2) Not negating the FileOption parameter. A negative FileOption is not applicable to HTTPPost. Appending would be a function of what ever service reprsented by mis_ott.php. Functions like LIST/APPEND are not applicable to HTTPPost, but are used by FTPClient.
http_put_response = "" http_header = "" http_put_tx = HTTPPost (SERVER_PATH,"Butinah_sonde_data", http_put_response, http_header,0,0,Min,1008)
Your suggestion to clear http_put_response and http_header before each call of HTTPPost is a good one, as it ensures that each request is independent and doesn’t carry over any residual data from the previous one.
Also, your point about not negating the FileOption parameter is valid. In the context of HTTPPost, a negative FileOption isn’t applicable. The appending function would be dependent on the service represented by mis_ott.php.
Here’s how you might modify your code:
http_put_response = "" http_header = "" http_put_tx = HTTPPost (SERVER_PATH,"Butinah_sonde_data", http_put_response, http_header,0,0,Min,1008)
This should send data to the server at 15-minute intervals and append to the same file, assuming that the server-side script at mis_ott.php is set up to handle data in this way.
Remember to test your setup thoroughly to ensure that everything (especially geometry dash) is working as expected.
