ESP_BD_ADDR_LEN	Bluetooth address length.
ESP_BLE_ENC_KEY_MASK	Used to exchange the encryption key in the init key & response key.
ESP_BLE_ID_KEY_MASK	Used to exchange the IRK key in the init key & response key.
ESP_BLE_CSR_KEY_MASK	Used to exchange the CSRK key in the init key & response key.
ESP_BLE_LINK_KEY_MASK	Used to exchange the link key(this key just used in the BLE & BR/EDR coexist mode) in the init key & response key.
ESP_APP_ID_MIN	Minimum of the application id.
ESP_APP_ID_MAX	Maximum of the application id.
ESP_BD_ADDR_STR
ESP_BD_ADDR_HEX(addr)
