Nexus 7更换NFC控制器,导致不再支持读取Mifare Classic NFC 1k Tags

 In a review conducted by Anandtech, it was found that the Nexus 4 makes use of the Broadcom BCM20793 NFC controller. All previous NFC-enabled Nexus devices (Nexus S, Galaxy Nexus, Nexus Q and Nexus 7), as well as the vast majority of non-Nexus Android phones, have made use of NXP's PN544 controller.

 人们发现,在Nexus 4利用Broadcom的BCM20793 NFC控制器。 以前所有NFC功能的Nexus设备(的Nexus S,Galaxy Nexus的,的Nexus Q和的Nexus 7),以及非Nexus的Andr​​oid手机的绝大多数,都利用恩智浦的PN544控制器。 

 

 太坑了。。。Nexus 4 使用NXP's PN544 controller,而到了 Nexus 7,开始使用 Broadcom BCM20793 NFC controller,导致 m1 卡不能被读取了。以前设计的程序无法正常运行。以后挑选设备的要注意了。
