559 +== 2.5 Datalog Feature ==
560 +
561 +
562 +Datalog Feature is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, LDS12-LB will store the reading for future retrieving purposes.

564 +
565 +=== 2.5.1 Ways to get datalog via LoRaWAN ===
566 +
567 +
568 +Set PNACKMD=1, LDS12-LB will wait for ACK for every uplink, when there is no LoRaWAN network,LDS12-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.

571 +a) LDS12-LB will do an ACK check for data records sending to make sure every data arrive server.

573 +* (((
574 +b) LDS12-LB will send data in **CONFIRMED Mode** when PNACKMD=1, but LDS12-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 LDS12-LB gets a ACK, LDS12-LB will consider there is a network connection and resend all NONE-ACK messages.

604 +Once LDS12-LB Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to LDS12-LB. If LDS12-LB fails to get the time from the server, LDS12-LB will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
605 +
606 +(% 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.**

649 +The LiDAR probe is based on TOF, namely, Time of Flight principle. To be specific, the product emits modulation wave of near infrared ray on a periodic basis, which will be reflected after contacting object. The product obtains the time of flight by measuring round-trip phase difference and then calculates relative range between the product and the detection object, as shown below.
