26 == 1.1 What is LoRaWAN Microwave Radar Distance Sensor ==
27
28
29 The Dragino MDS120-LB/LS is a (% style="color:blue" %)**LoRaWAN Microwave Radar distance sensor**(%%). It uses use Microwave Radar to detect the distance between sensor and different objects. Different from ultrosonic or Lidar measurement. Microwave Radar is (% style="color:blue" %)**more reliable for condensation / dusty environment**(%%). It can sense correct distance even there is water or think dust on top of the sensor.
30
31 The MDS120-LB/LS 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.
32
33 The LoRa wireless technology used in MDS120-LB/LS 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.
34
35 MDS120-LB/LS (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
36
37 MDS120-LB/LS is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery **(%%)or (% style="color:blue" %)**solar powered + li-on battery**(%%) , it is designed for long term use up to 5 years.
38
39 Each MDS120-LB/LS 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.

177
178 The MDS120-LB/LS 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 MDS120-LB/LS. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

184
185 Following is an example for how to join the [[TTN v3 LoRaWAN Network>>url:https://console.cloud.thethings.network/]]. Below is the network structure; we use the [[LPS8v2>>url:https://www.dragino.com/products/lora-lorawan-gateway/item/228-lps8v2.html]] as a LoRaWAN gateway in this example.
186
187 The LPS8v2 is already set to connected to [[TTN network >>url:https://console.cloud.thethings.network/]], so what we need to now is configure the TTN server.

382 == 2.6 Datalog Feature ==
383
384
385 Datalog Feature is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, MDS120-LB/LS will store the reading for future retrieving purposes.
386
387
388 === 2.6.1 Ways to get datalog via LoRaWAN ===
389
390
391 Set PNACKMD=1, MDS120-LB/LS will wait for ACK for every uplink, when there is no LoRaWAN network, MDS120-LB/LS 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.
392
393 * (((
394 a) MDS120-LB/LS will do an ACK check for data records sending to make sure every data arrive server.
395 )))
396 * (((
397 b) MDS120-LB/LS will send data in **CONFIRMED Mode** when PNACKMD=1, but MDS120-LB/LS 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 MDS120-LB/LS gets a ACK, MDS120-LB/LS will consider there is a network connection and resend all NONE-ACK messages.

399
400 === 2.6.2 Unix TimeStamp ===
401
402
403 MDS120-LB/LS uses Unix TimeStamp format based on

414 So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
415
416
417 === 2.6.3 Set Device Time ===
418
419
420 User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
421
422 Once MDS120-LB/LS Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to MDS120-LB/LS. If MDS120-LB/LS fails to get the time from the server, MDS120-LB/LS will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
423
424 (% 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.**

430 Users can poll sensor values based on timestamps. Below is the downlink command.
