前言：

针对HID设备配对绑定获取信息常用代码做汇总。

一、获取主机MAC地址

需先绑定以获取固定MAC地址

{
    gapBondRec_t bond_info;

    uint8_t adv_event_type = GAP_ADTYPE_ADV_HDC_DIRECT_IND;
    uint8_t Adv_Direct_Addr[B_ADDR_LEN];
    uint8_t Adv_Direct_Type = adv_direct.advtype;

    tmos_snv_read(mainRecordNvID(0), sizeof(gapBondRec_t), &bond_info);
    tmos_memcpy(Adv_Direct_Addr, bond_info.publicAddr, 6);

    PRINT("Adv Direct type：%#x (", Adv_Direct_Type);
    for (int i = 0; i < 6; i++) {
        PRINT("%#x ", Adv_Direct_Addr[i]);
    } PRINT(")\n");
}

二、获取当前绑定数目

uint16_t bonding = 0;
if(events & BONDNUM_EVT)
{
    GAPBondMgr_GetParameter(GAPBOND_BOND_COUNT, &bonding);    //2022/7/21
    printf("BondNum = %x\n", bonding);
    tmos_start_task(hidEmuTaskId, BONDNUM_EVT, 6400);
    return (events ^ BONDNUM_EVT);
}
