	804	+This feature support since firmware v1.4
	805	+
	806	+RS485-LN supports listening mode, it can listen the RS485 network packets and send them via LoRaWAN uplink. Below is the structure. The blue arrow shows the RS485 network packets to RS485-LN.

	827	+The RS485-LN is set to AT+RXMODE=2,1000
	828	+
	829	+There is a two Modbus commands in the RS485 network as below:
	830	+
	831	+The Modbus master send a command: (% style="background-color:#ffc000" %)01 03 00 00 00 02 c4 0b
	832	+
	833	+And Modbus slave reply with: (% style="background-color:green" %)01 03 04 00 00 00 00 fa 33
	834	+
	835	+RS485-LN will capture both and send the uplink: (% style="background-color:#ffc000" %)01 03 00 00 00 02 c4 0b  (% style="background-color:green" %)01 03 04 00 00 00 00 fa 33

	838	+
	839	+
	840	+Notice: Listening mode can work with the default polling mode of RS485-LN. When RS485-LN is in to send the RS485 commands (from AT+COMMANDx), the listening mode will be interrupt for a while.
