ENUM NFC_VENDOR_CMDS(9)

💖 NAME 💖

enum nfc_vendor_cmds — supported nfc vendor commands. This is the enum nfc_vendor_cmds(9) page from the Kernel API Manual, bestie, and it’s literally all about the vendor command glow-up. ✨

✨ SYNOPSIS ✨

okay so here’s the enum, exactly as it shows up — no cap, no edits:

enum nfc_vendor_cmds {
    FACTORY_MODE ,
    HCI_CLEAR_ALL_PIPES ,
    HCI_DM_PUT_DATA ,
    HCI_DM_UPDATE_AID ,
    HCI_DM_GET_INFO ,
    HCI_DM_GET_DATA ,
    HCI_DM_LOAD ,
    HCI_DM_RESET ,
    HCI_GET_PARAM ,
    HCI_DM_FIELD_GENERATOR ,
    HCI_LOOPBACK

};

🔧 Constants 🔧

• FACTORY_MODE — lets you set the driver into a mode where no secure element are activated. It does not consider any NFC_ATTR_VENDOR_DATA. 💅
• HCI_CLEAR_ALL_PIPES — lets you execute a HCI clear all pipes command. It does not consider any NFC_ATTR_VENDOR_DATA. ✨
• HCI_DM_PUT_DATA — lets you configure specific CLF registry as for example RF trimmings or low level drivers configurations (I2C, SPI, SWP). 🎀
• HCI_DM_UPDATE_AID — lets you configure an AID routing into the CLF routing table following RF technology, CLF mode or protocol. 🦋
• HCI_DM_GET_INFO — lets you retrieve CLF information. 🌸
• HCI_DM_GET_DATA — lets you retrieve CLF configurable data such as low level drivers configurations or RF trimmings. 🫶
• HCI_DM_LOAD — lets you load a firmware into the CLF. A complete packet can be more than 8KB. 😭
• HCI_DM_RESET — lets you run a CLF reset in order to "commit" CLF configuration changes without CLF power off. 🔥
• HCI_GET_PARAM — lets you retrieve an HCI CLF parameter (for example the white list). 👑
• HCI_DM_FIELD_GENERATOR — lets you generate different kind of RF technology. When using this command to anti-collision is done. 🌈
• HCI_LOOPBACK — lets you echo a command and test the Dh to CLF connectivity. ⭐
