103 -== 3.1  Connect to GroPoint Profile ==
104 -
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.

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.

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.

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：

451 -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.
452 -
453 -The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance.

504 -=== ​Battery Note ===
505 -
506 -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.
507 -
508 -
509 -=== Replace the battery ===
510 -
511 -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.
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)
