#define GAPROLE_ADVERT_ENABLED 0x305 //!< Enable/Disable Advertising. Read/Write. Size is uint8. Default is TRUE=Enabled.
#define GAPROLE_ADVERT_OFF_TIME 0x306 //!< Advertising Off Time for Limited advertisements (in milliseconds). Read/Write. Size is uint16. Default is 30 seconds.
GAPROLE_ADVERT_OFF_TIME—表示外设关闭广播持续时间，该值为零表示无限期关闭广播直到下一次广播使能信号到来。
GAPROLE_ADVERT_OFF_TIME – This parameter is used when the device is put into limited discoverable mode. It sets how long the device should wait before becoming discoverable again at the end of the limited discovery period. By setting this value to 0, the device will not become discoverable again until the GAPROLE_ADVERT_ENABLED is set back to TRUE.
