241 -# d) in Custom page, select custom script to point to this script. (put this script in /etc/iot/scripts directory)
242 -#
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

254 -# Step2 will cause below change:
255 -# Device1: DI1: ON, DI2: ON , DO1: OFF, DO2: OFF
256 -# Device2: DI1: OFF, DI2: OFF , DO1: ON, DO2: ON

260 -# Device2: DI1: OFF, DI2: OFF , DO1: ON, DO2: ON
