Edwin Chen 8.1 11 == What is GroPoint Air ==
Edwin Chen 7.1 12
Edwin Chen 2.1 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.
Edwin Chen 1.1 14
Edwin Chen 3.1 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**(%%).
Edwin Chen 1.1 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.

Edwin Chen 57.2 74 = How to use? =
Edwin Chen 36.1 75
Edwin Chen 57.2 76 == Connect to GroPoint Profile ==
David Huang 42.1 77
Edwin Chen 57.2 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
David Huang 42.1 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
Edwin Chen 56.1 91 == Example to use for LoRaWAN network ==
David Huang 42.1 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:

Edwin Chen 56.2 138 == Uplink Payload Analyze ==
139
David Huang 61.1 140 Uplink payloads have two types:
Edwin Chen 56.2 141
David Huang 61.1 142 * (((
143 Report temperature and humidity status normally: Use FPORT=2
144 )))
145 * (((
146 Other control commands: Use other FPORT fields.
147 )))
Edwin Chen 56.2 148
David Huang 61.1 149 The application server should parse the correct value based on FPORT settings.
Edwin Chen 56.2 150
David Huang 61.1 151
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.

Edwin Chen 55.3 180 == Show data on Datacake ==
David Huang 42.1 181
182 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:
183
184 **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]]

239 **Downlink Command: 0x01**
240
241 Format: Command Code (0x01) followed by 3 bytes time value.
242
243 If the downlink payload=0100003C, it means set the END Node’s Transmit Interval to 0x00003C=60(S), while type code is 01.
244
Edwin Chen 35.1 245 * Example 1: Downlink Payload: 0100001E ~/~/ Set Transmit Interval (TDC) = 30 seconds

268
David Huang 62.1 269 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.
270

400 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.
401
402 The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance.

Edwin Chen 29.1 453 === ​Battery Note ===
454
Edwin Chen 30.1 455 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.
Edwin Chen 28.1 456
457
Edwin Chen 29.1 458 === Replace the battery ===
459
Edwin Chen 30.1 460 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.
Edwin Chen 28.1 461
Edwin Chen 30.1 462 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)

Edwin Chen 18.1 482
David Huang 62.1 483 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.
