21 == 1.1 What is LoRaWAN LiDAR ToF Distance Sensor ==
22
23
24 The Dragino LDS12-LB is a (% style="color:blue" %)**LoRaWAN LiDAR ToF (Time of Flight) Distance Sensor**(%%) for Internet of Things solution. It is capable to measure the distance to an object as close as 10 centimeters (+/- 5cm up to 6m) and as far as 12 meters (+/-1% starting at 6m)!. The LiDAR probe uses laser induction technology for distance measurement.
25
26 The LDS12-LB can be applied to scenarios such as horizontal distance measurement, parking management system, object proximity and presence detection, intelligent trash can management system, robot obstacle avoidance, automatic control, sewer, etc.
27
28 It detects the distance between the measured object and the sensor, and uploads the value via wireless to LoRaWAN IoT Server.
29
30 The LoRa wireless technology used in LDS12-LB allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
31
32 LDS12-LB (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
33
34 LDS12-LB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long term use up to 5 years.
35
36 Each LDS12-LB is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.

283
284 The LDS12-LB is configured as (% style="color:#037691" %)**LoRaWAN OTAA Class A**(%%) mode by default. It has OTAA keys to join LoRaWAN network. 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 LDS12-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

486
487
488 === 2.6.1 Ways to get datalog via LoRaWAN ===
489
490
491 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.

497 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.

524
525 User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
526
527 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).
528
529 (% 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.**
