Determine the logic behind the Vectronic data ID #24

Open HansMartinMT opened 5 years ago

HansMartinMT commented 5 years ago

We want to determine if we can use the data point ID to allow us to access data starting after a previous download. If the data point ID's are unique to 'our' collars, this could allow us to use a single ID to access for all of the collars instead of having a unique data point ID for each collar.

By data point ID, do you mean the first column in a vectronic text file? Eg. the "2674" in the following snippet:

2674 16245 2019-01-01 20:00:31 2019-01-01 12:00:31

Just curious if I can help answer your question. I have lots of these to look at. At first glance, they appear to just increment with each position record for a collar. Not unique to collars or accounts.

Yeah, one guess is that they increment across some large set of collars or even all active collars?

@HansMartinMT or @foresthayes can you please respond to this question "By data point ID, do you mean the first column in a vectronic text file?"

foresthayes commented 5 years ago

Using collar::fetch_vectronics the first column I get back is "idPosition". Below are the last 50 values for a single collar. I have not been able to figure out what these values relate to although they do seem to always increase. Note that the increment is often ~50,000 but is also highly variable.
