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.

57 = Configure GroPoint Air via AT Command or LoRaWAN Downlink =
58
59 Use can configure GroPoint Air via AT Command or LoRaWAN Downlink.
60
61 * 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]].
62 * LoRaWAN Downlink instruction for different platforms: [[IoT LoRaWAN Server>>url:http://8.211.40.43/xwiki/bin/view/Main/]]
63
64 There are two kinds of commands to configure GroPoint, they are:
65
66 * (((
67 **~ General Commands**.
68 )))
69
70 These commands are to configure:
71
72 * (((
73 General system settings like: uplink interval.

75 * (((
76 LoRaWAN protocol & radio-related command.
77 )))
78
79 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/]]

231 = Battery & How to replace =
232
233 == Battery Type ==
234
235 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.
236
237 The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance.

247 == Power Consumption Analyze ==
248
249 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.
250
251 Instruction to use as below:
252
253
254 **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/]]

288 === ​Battery Note ===
289
290 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.
291
292
293 === Replace the battery ===
294
295 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.
296
297 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)
