== 1.1 What is GroPoint Air ==

30

31

32

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.

33

34

(% 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**(%%).

35

36

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.

37

38

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.

39

40

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.

= 3. How to use? =

== 3.1 Connect to GroPoint Profile ==

102

103

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:

104

105

* Support RS485 Interface

106

* with M12 5pin connector.

107

108

Such model in GroPoint Profile is: (% style="color:blue" %)**2625-N-T-x-M-M **(%%)(Where x is different depending on how many levels it detects).

109

110

111

== 3.2 Connect to LoRaWAN Network? ==

112

113

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

114

115

116

== 3.3 Example to use for LoRaWAN network ==

117

118

This section shows an example of how to join the TTN V3 LoRaWAN IoT server. Usages with other LoRaWAN IoT servers are similar.

119

120

* 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>>||anchor="H3.4A0UplinkPayloadAnalyze"]] for detail.

121

122

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:

123

124

125

(% style="color:blue" %)**Step 1**(%%): Create a device in TTN V3 with the OTAA keys from GroPoint Air.

126

127

Each GroPoint Air is shipped with a sticker with the default device EUI as below:

== 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:

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.

212

213

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:

214

215

This means that the interrupt mode of the end node is set to 0x000003=3 (rising edge trigger), and the type code is 06.

== 4.3 Set the sensor delay time ==

314

315

Feature: Change the sensor delay time.

316

317

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.

318

319

The default delay is 1000ms.

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.

512

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.

515

=== 6.2.2 Replace the battery ===

518

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.

)))

(((

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).
