104 == 3.1  Connect to GroPoint Profile ==
105
106 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:
107
108 * Support RS485 Interface
109 * with M12 5pin connector.
110
111 Such model in GroPoint Profile is: **2625-N-T-x-M-M **(Where x is different depending on how many levels it detects).
112
113
114 == 3.2  Connect to LoRaWAN Network? ==
115
116 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
117
118
119 == 3.3  Example to use for LoRaWAN network ==
120
121 This section shows an example of how to join the TTN V3 LoRaWAN IoT server. Usages with other LoRaWAN IoT servers are similar.
122
123 * 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.
124
125 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:
126
127 **Step 1**: Create a device in TTN V3 with the OTAA keys from GroPoint Air.
128
129 Each GroPoint Air is shipped with a sticker with the default device EUI as below:

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

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

448 GroPoint Air is equipped with a [[8500mAH ER26500 Li-SOCI2 battery>>url:https://www.dragino.com/downloads/index.php?dir=datasheet/Battery/ER26500/]]. The battery is an un-rechargeable battery with a low discharge rate targeting more than 5 years use. This type of battery is commonly used in IoT targets for long-term running, such as water meters.
449
450 The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance.

501 === ​6.2.1  Battery Note ===
502
503 The Li-SICO battery is designed for small current / long period applications. It is not good to use a high current, short period transmit method. The recommended minimum period for use of this battery is 5 minutes. If you use a shorter period to transmit LoRa, then the battery life may be decreased.
504
505
506 === 6.2.2  Replace the battery ===
507
508 (((
509 You can change the battery in GroPoint Air. The type of battery is not limited as long as the output is between 3v to 3.6v.

511
512 (((
513 The default battery pack of GroPoint Air includes a ER26500 plus supercapacitor. If users can’t find this pack locally, they can find ER26500 or equivalence, which will also work in most cases. The SPC can enlarge the battery life for high-frequency use (update period below 5 minutes).
