18 == 1.1 What is LoRaWAN Distance Detection Sensor ==
19
20
21 The Dragino DDS75-LB is a (% style="color:blue" %)** LoRaWAN Distance Detection Sensor**(%%) for Internet of Things solution. It is used to measure the distance between the sensor and a flat object. The distance detection sensor is a module that uses (% style="color:blue" %)** ultrasonic sensing technology**(%%) for (% style="color:blue" %)**distance measurement**(%%), and (% style="color:blue" %)** temperature compensation**(%%) is performed internally to improve the reliability of data. The DDS75-LB can be applied to scenarios such as horizontal distance measurement, liquid level measurement, parking management system, object proximity and presence detection, intelligent trash can management system, robot obstacle avoidance, automatic control, sewer, bottom water level monitoring, etc.
22
23 It detects the distance(% style="color:blue" %)**  between the measured object and the sensor**(%%), and uploads the value via wireless to LoRaWAN IoT Server.
24
25 The LoRa wireless technology used in DDS75-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.
26
27 DDS75-LB (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
28
29 DDS75-LB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long term use up to 5 years.
30
31 Each DDS75-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.

209
210
211 The DDS75-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 DDS75-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

217
218 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.
219
220 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.

484 === 2.6.1 Ways to get datalog via LoRaWAN ===
485
486
487 Set PNACKMD=1, DDS75-LB will wait for ACK for every uplink, when there is no LoRaWAN network,DDS75-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.

In a future uplink if DDS75-LB gets a ACK, DDS75-LB will consider there is a network connection and resend all NONE-ACK messages.

523 Once DDS75-LB Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to DDS75-LB. If DDS75-LB fails to get the time from the server, DDS75-LB will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
524
525 (% 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.

729
730
731 == 7.3  Why does the sensor reading show 0 or "No sensor" ==
732
733
734 ~1. The measurement object is very close to the sensor, but in the blind spot of the sensor.
