30 (((
31 (((
32 The** Dragino LDS02 **is a **LoRaWAN Door Sensor** designed to detect door open/close status and send data to a LoRaWAN Network Server. Users can view the door status, open time, and open counts in an IoT platform by integrating it with the LoRaWAN Network Server.
33 )))
34
35 (((
36 The sensor is powered by **two AAA batteries**, making it suitable for long-term use. These batteries can provide approximately 16,000 to 70,000 uplink packets. When the batteries run out, users can easily open the enclosure and replace them with standard AAA batteries.
37
38 The device sends data periodically every day and for each door open/close action. It also **counts the number of door openings** and **calculates the duration of the last door opening**. Users can disable the uplink for each open/close event if preferred. In this mode, the device will count each event and upload the data periodically instead.
39
40 The LDS02 **features an open alarm**, which can be configured to send an alarm if the door remains open for a specified duration.
41
42 Each sensor comes with information (keys and identifiers) for LoRaWAN Network registration. Registering these keys with a LoRaWAN server allows the device to connect automatically upon powering on.
43
44
45 The following figure shows how the LDS02 is connected to a typical LoRaWAN network server.

110 = 3. How to Install LDS02 =
111
112
113 The LDS02 has two parts: sensor and the magnet. These parts can be attached to a surface using either screws or double sided tapes.For example, if you install it to detect door open/close events, the sensor part can be attached to the door frame, and the magnet can be attached to the door panel.
114
115
116 Fixing with screws:
117
118 * Each part has a bottom lid that can be detached from its enclosure. Detach the bottom lids of both the sensor and the magnet enclosures. You will notice two holes on each bottom lid for inserting screws. First, attach the bottom lids to the surface using screws, ensuring a minimal gap between them. Then snap the top part of the enclosure onto the bottom. You will hear a clicking sound once they are securely fitted together.
119
120 [[image:image-20231222111730-1.jpeg||height="428" width="686"]]
121
122
123 Fixing with double-sided adhesive pads:
124
125 * The double-sided adhesive pad included with the LDS01 has a pre-cut section that can be attached to the bottom of the magnet enclosure (first remove the protective backing of one side only). The remaining section should be affixed to the bottom of the sensor enclosure. Once the tape is in place, remove the protective backing and secure both enclosures to the surface, ensuring a minimal gap between them.

146
147
148 (((
149 The LDS02 is configured as a LoRaWAN Class A device by default. It contains a DevEUI, AppEUI, and AppKey, which allow it to join a LoRaWAN network using OTAA (Over-The-Air Activation). To connect the LDS02 to a LoRaWAN network, you need to configure these keys and identifiers with the LoRaWAN network server first, and then [[power on>>||anchor="H2.PowerONLDS02"]] the LDS02. The device will automatically join the network using OTAA. This device information can be found in your package, printed on a sticker.
150
151 [[image:image-20230426084924-1.png||height="229" width="493"]]
152
153 If you cannot set the device registration information, such as the DevEUI, AppEUI, and AppKey, in the network server, you must use the information generated by the network server, which differs from the information already stored on the device. In this case, you can use [[AT Command>>||anchor="H6.UseATCommand"]]s to write the new information to the device.

157 == 4.2 Example of Joining a LoRaWAN Network ==
158
159
160 The following figure shows how the LDS02 connects to [[The Things Stack>>https://eu1.cloud.thethings.network/]]. The LDS02 sends messages (uplinks) to The Things Stack via a LoRaWAN gateway (e.g., Dragino LPS8N) and can also receive messages (downlinks) from The Things Stack. The Things Stack can be integrated with ThingsEye, allowing it to forward uplinks to ThingsEye. ThingsEye is an IoT platform used for visualizing and analyzing sensor data. You can also send downlinks from ThingsEye (via The Things Stack) to the LDS02.

170 * The LDS02 is installed with the magnet on the door and the sensor part on the door frame to detect open/close events and send the status to the LoRaWAN server. The LDS02 will uplink two types of messages to the server:
171 ** A keep-alive message, which is sent once per day.
172 ** A door event message when a door is opened or closed ([[Alarm event can be disabled>>||anchor="H7.3CanIdisableuplinkforeacheventtosavebatterylife3F"]])

453
454
455 The Things Stack can be integrated with many IoT platforms, including ThingsEye and Datacake, for visualizing and analyzing data coming from the LDS02. Most of these IoT platforms also support sending downlinks to the LDS02.
456
457 === 4.5.1 Integrate with ThingsEye ===
458
459
460 The Things Stack application supports integration with ThingsEye.io. Once integrated, ThingsEye.io acts as an MQTT client for The Things Stack MQTT broker, allowing it to subscribe to upstream traffic and publish downlink traffic.
461
462
463 ==== 4.5.1.1 Configuring The Things Stack ====
464
465 We use The Things Stack Sandbox in this example:
466
467 * In **The Things Stack Sandbox**, go to the **Application **for the LDS02 you added.
468 * Select **MQTT** under **Integrations** in the left menu.
469 * In the **Connection information **section, under **Connection credentials**, The Things Stack displays an auto-generated **username**. You can use it or provide a new one.
470 * Click the **Generate new API key** button to generate a password. You can view it by clicking on the **visibility toggle/eye** icon. The API key works as the password.

933 **It is very important to press the reset button after the upgrade. This sets the device to work in Low Power mode.**
934
935 **If you change to a different LoRa frequency band/region, you need to use the AT+FDR command to restore the factory data after the program is successfully applied.**
936
937
938 == 7.2 How to change the LoRa Frequency Bands/Region? ==
939
940
941 If you have the US915 frequency and want to change it to the AS923 frequency, you can follow the same instructions mentioned in the [[How to upgrade the image?>>doc:||anchor="How to upgrade the image?"]] section to upgrade the image. When downloading the image, select the required file.
942
943
944 == 7.3 Can I disable uplinks for each event to save battery life? ==
945
946
947 Yes, you can use one of the methods below:
948
949
950 (% style="color:blue" %)**Via AT Command**:
951
952 (% style="color:red" %)**AT+DISALARM=1**(%%) : The end node will only send packets during the TDC time.
953
954 (% style="color:red" %)**AT+DISALARM=0**(%%) : The end node will send packets either during the TDC time or when there is a status change in the door sensor.
955
956
957 (% style="color:blue" %)**Via LoRaWAN downlink Command**:
958
959 (% style="color:red" %)**0xA701**(%%) : Equivalent to AT+DISALARM=1
960
961 (% style="color:red" %)**0xA700**(%%) : Equivalent to AT+DISALARM=0
962
963
964 == 7.4 How can I change the Subband for LDS02? ==
965
966
967 **Before v1.6 firmware:**
968 LDS02 operates in Subband 2 by default in the AU915/US915 band. If the LoRaWAN server operates on another subband, LDS02 may have trouble joining the server. In this case, the user can use the AT command to change the subband. See the AT Command chapter for hardware connection details. Below are the steps to change the subband:
969
970 1. Press the reset button.
971 1. Send the password **123456**.
972 1. Send the command: **AT+CFREQBANDMASK=0006** (use 0001 for Subband 1, 0002 for Subband 2, etc.).
973 1. Press the reset button to restart and switch to the new subband.

1002
1003
1004 **Since firmware v1.6:**
1005
1006 LDS02 works with the channel mask 0x0000, which covers all subbands. Therefore, there is no need to use AT commands to change the subband, and it will work for every subband.
1007
1008
1009 == 7.5 My sensor worked for Helium AU915 before, but now it doesn't work. Why? ==
1010
1011
1012 This is a sub-band issue. See chapter 7.4. Helium changed the sub-band for AU915 from subband 2 to subband 6, which caused the sensor to stop working.
1013
1014
1015 == 7.6 Why do I see different working temperatures for the device? ==
1016
1017
1018 The working temperature range of the device depends on the battery the user chooses.
1019
1020 * A standard AAA battery can support a working range of -10°C to 50°C.
1021 * A special AAA battery can support a working range of -40°C to 60°C. For example, [[Energizer L92>>url:https://data.energizer.com/pdfs/l92.pdf]]
1022
1023 == 7.7 The device keeps rejoining the network and is not working properly ==
1024
1025
1026 **Cause of the problem:**
1027
1028 When the DR of AU915 and AS923 is 2 or the DR of US915 is 0, upon receiving the MAC Command from the server, the node will enter deep sleep and will not send packets because the attached MAC answer exceeds the number of bytes.
1029
1030 **Solution:**
1031
1032 1. Manually restart the device, then downlink 21 03 (only needs to be set once to be effective).
1033 1. Manually restart the device, then set AT+RPL=3 (only needs to be set once to be effective).
1034 1. Update the firmware to version v1.8 or above.
