74 = How to use? =
75
76 == Connect to GroPoint Profile ==
77
78 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:
79
80 * Support RS485 Interface
81 * with M12 5pin connector.
82
83 Such model in GroPoint Profile is: **2625-N-T-x-M-M **(Where x is different depending on how many levels it detects).
84
85
86 == Connect to LoRaWAN Network? ==
87
88 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
89
90
91 == Example to use for LoRaWAN network ==
92
93 This section shows an example of how to join the TTN V3 LoRaWAN IoT server. Usages with other LoRaWAN IoT servers are similar.
94
95 * 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.
96
97 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:
98
99 **Step 1**: Create a device in TTN V3 with the OTAA keys from GroPoint Air.
100
101 Each GroPoint Air is shipped with a sticker with the default device EUI as below:

138 == Uplink Payload Analyze ==
139
140 Uplink payloads have two types:
141
142 * (((
143 Report temperature and humidity status normally: Use FPORT=2
144 )))
145 * (((
146 Other control commands: Use other FPORT fields.
147 )))
148
149 The application server should parse the correct value based on FPORT settings.
150
151
152 == temperature and humidity Value, Uplink FPORT~=2 ==
153
154
155 GroPoint Air will send this uplink after Device Status once join the LoRaWAN network successfully. And GroPoint Air will:
156
157 periodically send this uplink every 20 minutes, this interval can be changed.
158
159 The drawing below shows the probe dimensions of the 2-8 segment probes, Temperature sen sor locations provided in table below:
160
161 [[image:image-20220621093414-1.png||height="932" width="816"]]
162
163 GroPoint Air's sensors come in six models:GPLP-2，GPLP-3，GPLP-4，GPLP-5，GPLP-6，GPLP-8.
164
165 The amount of temperature and humidity is different for each model, so the payload of each model is different.
166
167 Take GPLP-3 as an example：
168
169 Uplink Payload totals 21 bytes.

176 For US915 frequency, when DR=0 and the payload length exceeds 11, the DR of this packet is switched to 1.
177
178 For AU915 frequency, when DR=2，Dwelltime=1 and the payload length exceeds 11, the DR of this packet is switched to 3.
179
180 For AS923 frequency, when DR=2，Dwelltime=1 and the payload length exceeds 11, the DR of this packet is switched to 3.
181
182 == Show data on Datacake ==
183
184 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:
185
186 **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]]

455 === ​Battery Note ===
456
457 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.
458
459
460 === Replace the battery ===
461
462 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.
463
464 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)

481 In case if user can see the console output but can’t type input to the device. Please check if you already include the (% style="color:green" %)**ENTER**(%%) while sending out the command. Some serial tool doesn’t send (% style="color:green" %)**ENTER**(%%) while pressing the send key, user need to add ENTER in their string.
482
483 == Why i see the payload is 7FFF? ==
484
485 The device will judge the length of the data received by the serial port. If the length of the received data is 0, it means that there is a problem with the sensor communication or the sensor is not connected properly, it is invalid data, and the uploaded data is 7FFF.
