Phase data output explanation

[andrewruba]

Hi! This is a really fun api. I got it working with an older Thingmagic Vega reader I bought on ebay and my raspberry pi. I have a question about the phase of the tag. For me, it seems that the phase values are in the range 0 to 65535. Here is a typical time sequence of readings: [65257, 65473, 65359, 65311, 65290, 65465, 65336, 2080, 65052, 65369, 462, 88, 65239, 526, 265, 65439, 2006, 64968, 36, 544, 65143, 64625, 1593, 65406, 601]

Can someone help me understand what these represent? Is it 0 to pi or 0 to 2pi scaled to a 16 bit range? Is it some kind of encoding? Is it just an error?

Do you have your code?

I don't know exactly where it is at the moment (haven't played around with this in a while) but I recall only using a few lines of code to connect the reader and read the phase data from TagReadData Object. Nothing fancy.

Oh ok. I tried using their provided test.py, but it only prints out an empty list. If you have free time, do you mind trying to find it? Thanks!

Your reader might not have phase data to give to the api, just fyi. You can check the docs for your particular model.
