一从机多主机蓝牙连接里面很多UUID，为什么你这里值比较一个UUID呢？请给出多UUID比较的例子

如果在一个从机可以同时与多个主机设备建立蓝牙连接的情况下，每个主机设备可能使用不同的UUID来识别自己，那么需要使用一个UUID数组来存储这些UUID，并在BLE_GAP_EVT_ADV_REPORT事件处理程序中遍历数组以查找与收到的广播包匹配的UUID。

下面是一个示例代码，用于比较多个UUID：

#include <stdbool.h>
#include <stdint.h>
#include "nrf.h"
#include "nrf_soc.h"
#include "nrf_delay.h"
#include "app_uart.h"
#include "ble.h"
#include "ble_gap.h"

#define UUID_LENGTH     16

static uint8_t m_uuid1[UUID_LENGTH] = {0x01,0x02,0x03,0x04,0x05,0x06,0x07,0x08,0x09,0x0A,0x0B,0x0C,0x0D,0x0E,0x0F,0x10};
static uint8_t m_uuid2[UUID_LENGTH] = {0x11,0x12,0x13,0x14,0x15,0x16,0x17,0x18,0x19,0x1A,0x1B,0x1C,0x1D,0x1E,0x1F,0x20};
static uint8_t m_uuid3[UUID_LENGTH] = {0x21,0x22,0x23,0x24,0x25,0x26,0x27,0x28,0x29,0x2A,0x2B,0x2C,0x2D,0x2E,0x2F,0x30};

static uint32_t m_device_count1 = 0;
static uint32_t m_device_count2 = 0;
static uint32_t m_device_count3 = 0;

static uint8_t* m_uuid_array[] = {m_uuid1, m_uuid2, m_uuid3};
static uint32_t m_device_count_array[] = {&m_device_count1, &m_device_count2, &m_device_count3};
static uint8_t m_uuid_count = 3;

static void ble_evt_handler(ble_evt_t * p_ble_evt)
{
    switch (p_ble_evt->header.evt_id)
    {
        case BLE_GAP_EVT_ADV_REPORT:
        {
            ble_gap_evt_adv_report_t * p_adv_report = &p_ble_evt->evt.gap_evt.params.adv_report;

            if (p_adv_report->type.connectable)
            {
                for (int i = 0; i < m_uuid_count; i++)
                {
                    if (memcmp(p_adv_report->data.uuid.uuid128, m_uuid_array[i], UUID_LENGTH) == 0)
                    {
                        (*m_device_count_array[i])++;
                    }
                }
            }
        } break;

        default:
            // No implementation needed.
            break;
    }
}

int main(void)
{
    uint32_t err_code;

    // Initialize BLE stack.
    err_code = sd_softdevice_enable(NRF_CLOCK_LFCLKSRC_XTAL_20_PPM, NULL);
    APP_ERROR_CHECK(err_code);

    err_code = sd_ble_enable(&m_ram_start);
    APP_ERROR_CHECK(err_code);

    err_code = sd_ble_gap_adv_start(&m_adv_params);
    APP_ERROR_CHECK(err_code);

    while (true)
    {
        // Wait for events.
        err_code = sd_app_evt_wait();
        APP_ERROR_CHECK(err_code);

        // Handle BLE events.
        ble_evt_handler(p_ble_evt);
    }
}

在此示例代码中，我们定义了三个不同的UUID，并使用一个UUID数组来存储它们。在BLE_GAP_EVT_ADV_REPORT事件处理程序中，我们遍历UUID数组以查找与收到的广播包匹配的UUID。如果找到匹配的UUID，则增加相应的m_device_count变量的值。
