To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and press the button to activate the S31x-LB/LS. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

	206
	207	The LPS8V2 is already set to connected to [[TTN network >>url:https://console.cloud.thethings.network/]], so what we need to now is configure the TTN server.

	417
	418
73.4	419	Datalog Feature is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, S31x-LB/LS will store the reading for future retrieving purposes.
1.1	420
	421

	423
	424
76.10	425	Set PNACKMD=1, S31x-LB/LS will wait for ACK for every uplink, when there is no LoRaWAN network,S31x-LB/LS will mark these records with non-ack messages and store the sensor data, and it will send all messages (10s interval) after the network recovery.
1.1	426
44.1	427	* (((
73.4	428	a) S31x-LB/LS will do an ACK check for data records sending to make sure every data arrive server.
44.1	429	)))
	430	* (((
73.4	431	b) S31x-LB/LS will send data in CONFIRMED Mode when PNACKMD=1, but S31x-LB/LS won't re-transmit the packet if it doesn't get ACK, it will just mark it as a NONE-ACK message. In a future uplink if S31x-LB/LS gets a ACK, S31x-LB/LS will consider there is a network connection and resend all NONE-ACK messages.

1.1	433
	434	=== 2.5.2 Unix TimeStamp ===
	435

	449
	450
	451	=== 2.5.3 Set Device Time ===
	452
	453
14.24	454	User need to set (% style="color:blue" %)SYNCMOD=1(%%) to enable sync time via MAC command.
1.1	455
73.4	456	Once S31x-LB/LS Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to S31x-LB/LS. If S31x-LB/LS fails to get the time from the server, S31x-LB/LS will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
1.1	457
14.24	458	(% style="color:red" %)Note: LoRaWAN Server need to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature, Chirpstack,TTN V3 v3 and loriot support but TTN V3 v2 doesn't support. If server doesn't support this command, it will through away uplink packet with this command, so user will lose the packet with time request for TTN V3 v2 if SYNCMOD=1.

	498
	499	a) DR0: max is 11 bytes so one entry of data
