10. Data Logger
The logger utilizes circular buffer in FLASH memory. When it is full, the new data overwrites the
oldest one. In this manner FLASH memory stores full log all the time. There isn’t a command to clear
the log. A copy of the full log is always available for download.
The number of records depends on how long descriptions and what kind of characters are used. In
the worst case (15 bytes description with characters from the highest part of UTF-8) a number of
records are about 37000. This number is enough for 25 days with records on every 1 minute.
In most of the cases, the data logger can keep 53000 records, which is enough for 36 days with
records on every 1 minute.
The new records can be periodically uploaded as a file to a dedicated HTTP server in time intervals –
1, 2, 3, 4, 6, 8, 12 and 24 hours. The file is in CSV format. A semicolon is used as a delimiter.
The first row of the log file is always header. All rows, including the header, start with record ID and
time stamp.
