How can I switch ST25R3911B from reader/writer mode to the P2P mode

[XShi]

I want to know how to switch ST25R3911B from reader/writer mode to the P2P mode? Are there any register to config the working mode? In the datasheet, I find there is a register called "Operation control register" which can control the rx and tx enable. Is this register control the operating mode?

Hi,

these settings you will find in the Mode Settings Register.

Please beware that there are various lower protocol modes which can be used to implement P2P on the upper layers. All are based on one of A106, F212/424 technologies. But there are different modes:

• Passive initiatior (normal reader/writer modes)
• Passive Target
• Active initiator
• Active target modes

Out of these all except Passive Target are supported by ST25R3911B.
