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.

Edwin Chen 57.2 111
David Huang 42.1 112 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
113

Xiaoling 64.2 115 == 3.3  Example to use for LoRaWAN network ==
David Huang 42.1 116
117 This section shows an example of how to join the TTN V3 LoRaWAN IoT server. Usages with other LoRaWAN IoT servers are similar.
118
119 * 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.

443 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.
444
445 The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance.

Xiaoling 64.3 496 === ​6.2.1  Battery Note ===
Edwin Chen 29.1 497
Edwin Chen 30.1 498 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.

508 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).
