为了实现蓝牙OTA升级，需要用到的例程分别有BLE_ApplicationInstallManager、BLE_p2pServer_ota以及BLE_HeartRate_ota

首先向开发板中分别烧录BLE_ApplicationInstallManager和BLE_p2pServer_ota，观察两者的FLASH.ld文件，可以看到BLE_ApplicationInstallManager的烧录地址起始于0x08000000，而BLE_p2pServer_ota的烧录地址起始于0x08006000

BLE_ApplicationInstallManager

MEMORY
{
  RAM      (rw)     : ORIGIN = 0x20000010,   LENGTH = (512K - 0x10)

  FLASH    (rx)     : ORIGIN = 0x08000000,   LENGTH = 0x6000
}

BLE_p2pServer_ota

MEMORY
{
  RAM      (rw)     : ORIGIN = 0x20000020,   LENGTH = (512K - 0x20)

  NVM      (r)      : ORIGIN = 0x081FC000,   LENGTH = 16K
  DATA     (r)      : ORIGIN = 0x081FA000,   LENGTH = 8K
  FLASH    (rx)     : ORIGIN = 0x08006000,   LENGTH = 1000K
}

完成烧录后，打开ST BLE Toolbox，可以看到产生了p2pS_34

连接该设备，点击Over The Air Update Server用于OTA升级

在firmware中选择BLE_HeartRate_ota_reference.bin，点击烧录

完成烧录后，开发板会自动进行复位，再次打开ST BLE Toolbox，可以看到开发板对应为心跳检测的功能。连接进入界面后，可以看到以下内容
