76 76  
105 +GroPoint Air must be used with [[GroPoint Profile>>https://www.gropoint.com/products/soil-sensors/gropoint-profile]]. There are different interface model from GroPoint, users need to choose the one:
106 +
107 +* Support RS485 Interface
108 +* with M12 5pin connector.
109 +
110 +Such model in GroPoint Profile is: **2625-N-T-x-M-M **(Where x is different depending on how many levels it detects).
111 +
112 +
113 +== 3.2  Connect to LoRaWAN Network? ==
114 +
115 +Each GroPoint Air is shipped with a worldwide unique set of OTAA keys. To use GroPoint Air in a LoRaWAN network, user needs to input the OTAA keys in the LoRaWAN network server. So GroPoint Air can join the LoRaWAN network and start to transmit sensor data
116 +
117 +
118 +== 3.3  Example to use for LoRaWAN network ==
119 +
120 +This section shows an example of how to join the TTN V3 LoRaWAN IoT server. Usages with other LoRaWAN IoT servers are similar.
121 +
122 +* In this use case, the GroPoint Air measures soil moisture and temperature and sends the status to the LoRaWAN server.The GroPoint Air will uplink different types of messages to the LoRaWAN server. See [[Uplink payload>>url:http://wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/SW3L%20LoRaWAN%20Outdoor%20Flow%20Sensor/#H2.3UplinkPayload]] for detail.
123 +
124 +Assume the DLOS8 is already set to connect to the [[TTN V3 network >>url:https://eu1.cloud.thethings.network/]]. We need to add the GroPoint Air device in TTN V3:
125 +
126 +**Step 1**: Create a device in TTN V3 with the OTAA keys from GroPoint Air.
127 +
128 +Each GroPoint Air is shipped with a sticker with the default device EUI as below:

165 +== 3.4  Uplink Payload Analyze ==
166 +
167 +Uplink payloads have two types:
168 +
169 +* (((
170 +Report temperature and humidity status normally: Use FPORT=2
171 +)))
172 +* (((
173 +Other control commands: Use other FPORT fields.
174 +)))
175 +
176 +The application server should parse the correct value based on FPORT settings.
177 +
178 +
179 +== 3.5  temperature and humidity Value, Uplink FPORT~=2 ==
180 +
181 +
182 +GroPoint Air will send this uplink after Device Status once join the LoRaWAN network successfully. And GroPoint Air will:
183 +
184 +periodically send this uplink every 20 minutes, this interval can be changed.
185 +
186 +The drawing below shows the probe dimensions of the 2-8 segment probes, Temperature sen sor locations provided in table below:
187 +
188 +[[image:image-20220621093414-1.png||height="932" width="816"]]
189 +
190 +GroPoint Air's sensors come in six models:GPLP-2，GPLP-3，GPLP-4，GPLP-5，GPLP-6，GPLP-8.
191 +
192 +The amount of temperature and humidity is different for each model, so the payload of each model is different.
193 +
194 +Take GPLP-3 as an example：
195 +
196 +Uplink Payload totals 21 bytes.

201 +
202 +
203 +For US915 frequency, when DR=0 and the payload length exceeds 11, the DR of this packet is switched to 1.
204 +
205 +For AU915 frequency, when DR=2，Dwelltime=1 and the payload length exceeds 11, the DR of this packet is switched to 3.
206 +
207 +For AS923 frequency, when DR=2，Dwelltime=1 and the payload length exceeds 11, the DR of this packet is switched to 3.

210 +== 3.6  Show data on Datacake ==
211 +
212 +Datacake IoT platform provides a human-friendly interface to show the sensor data, once we have sensor data in TTN V3, we can use Datacake to connect to TTN V3 and see the data in Datacake. Below are the steps:
213 +
214 +**Step 1**: Link TTNv3 to Datacake [[https:~~/~~/docs.datacake.de/lorawan/lns/thethingsindustries#create-integration-on-tti>>url:https://docs.datacake.de/lorawan/lns/thethingsindustries#create-integration-on-tti]]
