1164 +
1165 +
1166 +(((
1167 +Datalog Feature is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, SDI-12-LB will store the reading for future retrieving purposes. There are two ways for IoT servers to get datalog from SDI-12-LB.
1168 +)))
1169 +
1170 +
1171 +=== 2.9.1 Ways to get datalog via LoRaWAN ===
1172 +
1173 +
1174 +There are two methods:
1175 +
1176 +(% style="color:blue" %)**Method 1:** (%%)IoT Server sends a downlink LoRaWAN command to [[poll the value>>||anchor="H2.8.4Pollsensorvalue"]] for specified time range.
1177 +
1178 +
1179 +(% style="color:blue" %)**Method 2: **(%%)Set PNACKMD=1, SDI-12-LB will wait for ACK for every uplink, when there is no LoRaWAN network, SDI-12-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.
1180 +
1181 +
1182 +(% style="color:red" %)**Note for method 2:**
1183 +
1184 +* a) SDI-12-LB will do an ACK check for data records sending to make sure every data arrive server.
1185 +* b) SDI-12-LB will send data in **CONFIRMED Mode** when PNACKMD=1, but SDI-12-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 SDI-12-LB gets a ACK, SDI-12-LB will consider there is a network connection and resend all NONE-ACK Message.
1186 +
1187 +=== 2.9.2 Unix TimeStamp ===

1237 +=== 2.9.4 Poll sensor value ===

1248 +Timestamp start and Timestamp end use Unix TimeStamp format as mentioned above. Devices will reply with all data log during this time period, use the uplink interval.
