how to disable random id feature on SN100T?

[jeremyliu]

Hi,

I want to get the static 7byte UID from SN100T as a card emulation, but I get a 4byte random id every time, is there a solution to solve this?  thanks a lot.

ok, get it, but I hope get more infomation about random id,  RID is enabled on SL3,  I can't change SL3 to SL2 or lower level,  but I think it can be enabled/disabled if it just a feature, I hava same issue on other NFC IC,  can you give me some suggestion? thanks a lot

is there any ideas?

HI @jeremyliu 

SN100T is not a mass market product.  You need to contact with NXP local FAE or representative for support.
