274 -#   and DO2 value. LPS8 will ask Device1 to change its DO1 to same as Device 2, and change the DO2 to the same as Device 2.
275 -#   ( The purpose of this step is to show that the Device2 has already do the change there).

277 -#  For example: If current status of Device1 and Device2 leds shows:
278 -#  Device1: DI1: ON, DI2: ON , DO1: OFF,  DO2: OFF
279 -#  Device2: DI1: OFF, DI2: OFF , DO1: OFF,  DO2: OFF

282 -#  Device1: DI1: ON, DI2: ON , DO1: OFF,  DO2: OFF
283 -#  Device2: DI1: OFF, DI2: OFF , DO1: ON,  DO2: ON
284 -# 
285 -#  Step3 will cause below change:
286 -#  Device1: DI1: ON, DI2: ON , DO1: ON,  DO2: ON
287 -#  Device2: DI1: OFF, DI2: OFF , DO1: ON,  DO2: ON
288 -#  So if a person is in the Device 1 location, he can check if the DO LED match DI LEDs on Device 1 to confirm
289 -#  whether the Device 2 has been changed.
