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.

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.
