243 +# How it works?
244 +# a) Devices 1 sends a uplink payload to LPS8. LPS8 will get the DI1 and DI2 info from the payload
245 +# b) LPS8 will send a message to Device 2 to set the Device2 DO1 = Device1 DI1, and Device DO2 = Device DI2.
246 +# c) Device2 will change DO1 and DO2 to according to the message from LPS8, and send back a message to LPS8 with the its DO1
247 +# 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.
248 +# ( The purpose of this step is to show that the Device2 has already do the change there).
249 +#
250 +# For example: If current status of Device1 and Device2 leds shows:
251 +# Device1: DI1: ON, DI2: ON , DO1: OFF, DO2: OFF
252 +# Device2: DI1: OFF, DI2: OFF , DO1: OFF, DO2: OFF
