782 -== 2.5 Frequency Plans ==
783 783  
785 +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 will store the reading for future retrieving purposes.
784 784  
785 -The SN50v3-LB uses OTAA mode and below frequency plans by default. If user want to use it with different frequency plan, please refer the AT command sets.

788 +=== 2.5.1 Ways to get datalog via LoRaWAN ===
789 +
790 +
791 +Set [[PNACKMD=1>>||anchor="H2.5.4DatalogUplinkpayloadA028FPORT3D329"]], S31x-LB will wait for ACK for every uplink, when there is no LoRaWAN network,S31x-LB 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.
792 +
793 +* a) S31x-LB will do an ACK check for data records sending to make sure every data arrive server.
794 +* b) S31x-LB will send data in **CONFIRMED Mode** when PNACKMD=1, but S31x-LB 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 gets a ACK, S31x-LB will consider there is a network connection and resend all NONE-ACK messages.
795 +
796 +Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)
797 +
798 +[[image:http://wiki.dragino.com/xwiki/bin/download/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LHT65N%20LoRaWAN%20Temperature%20%26%20Humidity%20Sensor%20Manual/WebHome/image-20220703111700-2.png?width=1119&height=381&rev=1.1||alt="图片-20220703111700-2.png" height="381" width="1119"]]

803 +S31x-LB uses Unix TimeStamp format based on

807 +User can get this time from link:  [[https:~~/~~/www.epochconverter.com/>>url:https://www.epochconverter.com/]] :

812 +
813 +So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
814 +
815 +
816 +=== 2.5.3 Set Device Time ===
817 +
818 +
819 +User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
820 +
821 +Once S31x-LB 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. If S31x-LB fails to get the time from the server, S31x-LB will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
822 +
823 +(% 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.**

844 +
845 +**No ACK Message**:  1: This message means this payload is fromn Uplink Message which doesn't get ACK from the server before ( for **PNACKMD=1** feature)
846 +
847 +**Poll Message Flag**: 1: This message is a poll message reply.
848 +
849 +* Poll Message Flag is set to 1.
850 +
851 +* Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
852 +
853 +For example, in US915 band, the max payload for different DR is:
854 +
855 +**a) DR0:** max is 11 bytes so one entry of data
856 +
857 +**b) DR1:** max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
858 +
859 +**c) DR2:** total payload includes 11 entries of data
860 +
861 +**d) DR3: **total payload includes 22 entries of data.
862 +
863 +If devise doesn't have any data in the polling time. Device will uplink 11 bytes of 0   
864 +

866 +**Example:**
867 +
868 +If S31x-LB has below data inside Flash:
