How to to change Gain on RFID-RC522 ???

[rantwhy]

so I just got my RFID-RC522 to work with my arduino But the range is absolute shit.  its less then the thickness of a sticky note stack.

I have read other forums on how to change it but no one gives a clear answer as to were to change the values rather it be in the library or the sketch itself. here is a link to the pdf on the unit http://www.nxp.com/documents/data_sheet/MFRC522.pdf   

My interests are page 59 Table 98.  were do I put the max value witch is 111? do I put it in the sketch or library? and how should it be formatted so I don't throw any  errors?


Thanks a bunch!!!!

What library are you using?

If you're using miguelbalboa's it looks like you should be able to do something like below in your sketch:

X.PCD_SetAntennaGain(0xFF);
Where X is your MFRC522 object var name

Im using the one from Addicore https://www.addicore.com/RFID-AddiKit-p/126.htm

The library was in the pdf as a link

I will try the miguelbalboa it seems like it comes with more bits Thanks! Ill let you know what I come up with

so I looked around and that line of code you showed me is only in the library were should I put this 0xFF value I tryed putting it everywhere and it just gives me errors can you post a mode descriptive example?

Keep the library the same. put that line of code in your sketch.
