285 +# b) ABP Mode ;
253 253  # c) AT+Mod=1

260 -# How it works?
261 -# a) Devices 1 sends a uplink payload to LPS8. LPS8 will get the DI1 and DI2 info from the payload
262 -# b) LPS8 will send a message to Device 2 to set the Device2 DO1 = Device1 DI1, and Device DO2 = Device DI2.
263 -# 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
264 -# 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.
265 -# ( The purpose of this step is to show that the Device2 has already do the change there).
266 -#
267 -# For example: If current status of Device1 and Device2 leds shows:
268 -# Device1: DI1: ON, DI2: ON , DO1: OFF, DO2: OFF
269 -# Device2: DI1: OFF, DI2: OFF , DO1: OFF, DO2: OFF

271 -# Step2 will cause below change:
272 -# Device1: DI1: ON, DI2: ON , DO1: OFF, DO2: OFF
273 -# Device2: DI1: OFF, DI2: OFF , DO1: ON, DO2: ON
274 -#
275 -# Step3 will cause below change:
276 -# Device1: DI1: ON, DI2: ON , DO1: ON, DO2: ON
277 -# Device2: DI1: OFF, DI2: OFF , DO1: ON, DO2: ON
278 -# 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
279 -# whether the Device 2 has been changed.}}}
