Reply To: Response code 504 from data.envirodiy.org

Hi again.

I ran another test overnight, again using a 2 minute sampling interval, with no code changes, but I removed the build flags for modem debugging from the platformio.ini. Here are the results:

• 427 total samples taken
• 52 sample events received a Response Code 504.
• 246 sample events received a Response Code 201.
• 155 of the samples are absent from the MMW database.

The new wrinkle here is that sometimes the Mayfly apparently didn’t attempt to send to MMW; this happened 129 times. In the log file, one of these occurrences looks like this:

… whereas a “normal” interval across consecutive samples, where the Mayfly does attempt to send, looks like this:

Any idea why the Mayfly didn’t send data at these times?

I’ll attach the log file and a time-series chart of when data was sent/not sent.

Thanks,

Matt
