hardware:pca1001
software:s120 v2.0.0 sdk 6.1.0
my question is the s120 v2.0.0 request hardware about the Chip Type. for example :xxaa xxac xxab
I'm not sure what you are asking about here. There is really not any official SDK for s120 v2 at the moment. Since you have the pca10001, I believe you have the QFAAG0. This chip version is compatible with SDK 6.1.0 and s120 1.0.0.
