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.

238 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.
239
240 The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance.

Edwin Chen 29.1 291 === ​Battery Note ===
292
Edwin Chen 30.1 293 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 28.1 294
295
Edwin Chen 29.1 296 === Replace the battery ===
297
Edwin Chen 30.1 298 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 28.1 299
Edwin Chen 30.1 300 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)
