20 == 1.1  What is GroPoint Air ==
21
22
Edwin Chen 2.1 23 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 24
Edwin Chen 3.1 25 (% 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 26
27 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.
28
29 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.
30
31 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.

Xiaoling 64.2 104 == 3.1  Connect to GroPoint Profile ==
David Huang 42.1 105
Edwin Chen 57.2 106 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:
107
108 * Support RS485 Interface
109 * with M12 5pin connector.
110
111 Such model in GroPoint Profile is: **2625-N-T-x-M-M **(Where x is different depending on how many levels it detects).

113
Xiaoling 64.2 114 == 3.2  Connect to LoRaWAN Network? ==
Edwin Chen 57.2 115
David Huang 42.1 116 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
117
118
Xiaoling 64.2 119 == 3.3  Example to use for LoRaWAN network ==
David Huang 42.1 120
121 This section shows an example of how to join the TTN V3 LoRaWAN IoT server. Usages with other LoRaWAN IoT servers are similar.
122
123 * 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
125 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:
126
127 **Step 1**: Create a device in TTN V3 with the OTAA keys from GroPoint Air.
128
129 Each GroPoint Air is shipped with a sticker with the default device EUI as below:

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.

448 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.
449
450 The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance.

462 Dragino Battery-powered products are all runs in Low Power mode. We have an updated battery calculator which base on the measurement of the real device. User can use this calculator to check the battery life and calculate the battery life if want to use different transmit intervals.
463
464 Instruction to use as below:
465
466
467 **Step 1**: Downlink the up-to-date DRAGINO_Battery_Life_Prediction_Table.xlsx from: [[https:~~/~~/www.dragino.com/downloads/index.pHp?dir=LoRa_End_Node/Battery_Analyze/>>url:https://www.dragino.com/downloads/index.php?dir=LoRa_End_Node/Battery_Analyze/]]

Xiaoling 64.3 501 === ​6.2.1  Battery Note ===
Edwin Chen 29.1 502
Edwin Chen 30.1 503 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 29.1 507
Xiaoling 64.3 508 (((
Edwin Chen 30.1 509 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.

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).
