	363	During each sampling, we need confirm what commands we need to send to the RS485 sensors to read data. After the RS485 sensors send back the value, it normally include some bytes and we only need a few from them for a shorten payload.
	364
	365	To save the LoRaWAN network bandwidth, we might need to read data from different sensors and combine their valid value into a short payload.
	366
	367	This section describes how to achieve above goals.
	368
	369	During each sampling, the RS485-LN can support 15 commands to read sensors. And combine the return to one or several uplink payloads.
	370

58.22	373
	374	~1. What commands RS485-LN will send to the RS485 sensors. There are total 15 commands from AT+COMMAD1, ATCOMMAND2,…, to AT+COMMANDF. All commands are of same grammar.
	375
	376	2. How to get wanted value the from RS485 sensors returns from by 1). There are total 15 AT Commands to handle the return, commands are AT+DATACUT1,AT+DATACUT2,…, AT+DATACUTF corresponding to the commands from 1). All commands are of same grammar.
	377
	378	3. Some RS485 device might has longer delay on reply, so user can use AT+CMDDL to set the timeout for getting reply after the RS485 command is sent. For example AT+CMDDL1=1000 to send the open time to 1000ms
	379
	380
	381	After we got the valid value from each RS485 commands, we need to combine them together with the command AT+DATAUP.
