11 == What is GroPoint Air ==
12
13 The Dragino GroPoint is a (% style="color:blue" %)**LoRaWAN Multi Soil Segment Converter**(%%) for IoT of Agriculture. It is designed to connect to [[GroPoint Profile Multi-depth Soil moisture and temperature profile Sensor>>url:https://www.gropoint.com/products/soil-sensors/gropoint-profile]] and get GroPoint Profile’s reading and send it to IoT server via LoRaWAN wireless network.
14
15 (% style="color:blue" %)**GroPoint Profile is plug-and-play with GroPoint Air**(%%) to get soil moisture and send via wireless. GroPoint Profile is powered by GroPoint Air, (% style="color:blue" %)**no need external power source**(%%).
16
17 The LoRa wireless technology used in GroPoint Air allows devices to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
18
19 GroPoint Air is powered by (% style="color:blue" %)**an 8500mAh Li-SOCI2 battery**(%%), it is designed for long-term use for up to 5 years.
20
21 Each GroPoint Air is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to the local LoRaWAN server and it will auto-connect after power on.

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.

177
178 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:
179
180 **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]]

204 * AT Command Connection: See [[FAQ>>url:http://8.211.40.43/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LLMS01-LoRaWAN%20Leaf%20Moisture%20Sensor%20User%20Manual/#H6.FAQ]].
205 * LoRaWAN Downlink instruction for different platforms: [[IoT LoRaWAN Server>>url:http://8.211.40.43/xwiki/bin/view/Main/]]
206
207 There are two kinds of commands to configure GroPoint Air, they are:
208
209 * (((

212
213 These commands are to configure:
214
215 * General system settings like: uplink interval.
216 * LoRaWAN protocol & radio-related command.
217
218 They are the same for all Dragino Device that support DLWS-005 LoRaWAN Stack. These commands can be found on the wiki: [[End Device AT Commands and Downlink Command>>url:http://8.211.40.43/xwiki/bin/view/Main/End%20Device%20AT%20Commands%20and%20Downlink%20Command/]]

234
235 **Downlink Command: 0x01**
236
237 Format: Command Code (0x01) followed by 3 bytes time value.
238
239 If the downlink payload=0100003C, it means set the END Node’s Transmit Interval to 0x00003C=60(S), while type code is 01.
240
241 * Example 1: Downlink Payload: 0100001E ~/~/ Set Transmit Interval (TDC) = 30 seconds
242 * Example 2: Downlink Payload: 0100003C ~/~/ Set Transmit Interval (TDC) = 60 seconds

251
252 **Downlink Command: 0x06**
253
254 Format: Command Code (0x06) followed by 3 bytes.
255
256 This means that the interrupt mode of the end node is set to 0x000003=3 (rising edge trigger), and the type code is 06.
257
258 * Example 1: Downlink Payload: 06000000 ~/~/ Turn off interrupt mode
259 * Example 2: Downlink Payload: 06000003 ~/~/ Set the interrupt mode to rising edge trigger
260
261 == (% id="cke_bm_55968S" style="display:none" %) (%%)3.3 Set the sensor delay time ==
262
263 Feature: Change the sensor delay time.
264
265 There are six models of GroPoint Air, and each model returns a different number of temperature and humidity. The more bytes of the returned value, the longer the delay. The AT+SDELAY command can adjust the time that the sensor returns data to the node, and can adjust different delays according to different types of sensors.
266
267 The default delay is 1000ms.
268
269 **AT Command: AT+SDELAY**

274
275 Format: Command Code (0xA1) followed by 3 bytes time value.
276
277 If the downlink payload=A10007D0, it means set the sensor delay time to 0x0007D0=2000ms, while type code is A1.
278
279 * Example 1: Downlink Payload: A10003E8 ~/~/ Set the sensor delay time = 1000ms
280 * Example 2: Downlink Payload: A10007D0 ~/~/ Set the sensor delay time = 2000ms

449 === ​Battery Note ===
450
451 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.
452
453
454 === Replace the battery ===
455
456 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.
457
458 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)

475 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.
476
477 == Why i see the payload is 7FFF? ==
478
479 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.
