可以使用AES-CCM模式对BLE广告数据包进行加密和解密。以下是使用ESP32开发板和Arduino IDE实现BLE广告包加密和解密的示例代码：

#include 
#include 
#include 
#include 
#include "esp_spp_api.h"
#include 

#define ADV_DATA_LEN    12
#define AES_KEY_LEN     16
#define AES_NONCE_LEN   12
#define AES_MIC_LEN     4

static uint8_t* g_aes_key = (uint8_t*)"1234567890123456";
static uint8_t g_aes_nonce[AES_NONCE_LEN] = {0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0A, 0x0B, 0x0C};
static uint8_t* g_adv_data = (uint8_t*)"Hello BLE";
static uint8_t g_enc_data[ADV_DATA_LEN + AES_MIC_LEN];

void setup() {
  Serial.begin(115200);
  BLEDevice::init("MyDevice");
}

void loop() {
  aesEncrypt(g_aes_key, g_aes_nonce, g_adv_data, ADV_DATA_LEN, g_enc_data, AES_MIC_LEN);

  BLEAdvertisementData adv_data;
  adv_data.setFlags(0x04);
  adv_data.addData(g_enc_data, ADV_DATA_LEN + AES_MIC_LEN);

  BLEAdvertisementDataScanResponse scan_rsp;
  scan_rsp.setAppearance(0x0080);

  BLEAdvertising *pAdvertising = BLEDevice::getAdvertising();
  pAdvertising->setAdvertisementData(adv_data);
  pAdvertising->setScanResponseData(scan_rsp);
  pAdvertising->start();
  delay(10000);
  pAdvertising->stop();  
}

void aesEncrypt(uint8_t *key, uint8_t *nonce, uint8_t *data, uint8_t data_len, uint8_t *enc_data, uint8_t mic_len) {
  uint8_t iv[AES_NONCE_LEN + 2];
  memcpy(iv, nonce, AES_NONCE_LEN);
  iv[AES_NONCE_LEN] = 0;
  iv[AES_NONCE_LEN + 1] = data_len;

  AES128_CCM aes_ccm;
  aes_ccm.setKey((byte*)key, AES_KEY_LEN);
  aes_ccm.setNonce((byte*)iv, AES_NONCE_LEN + 2);
  aes_ccm.encrypt(data, data_len, NULL, 0, enc_data, mic_len);
}

以上代码演
