	30
	31
2.1	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.
1.1	33
3.1	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(%%).
1.1	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.

42.1	102
57.2	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
65.5	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).
57.2	109
	110
64.2	111	== 3.2 Connect to LoRaWAN Network? ==
57.2	112
42.1	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
64.2	116	== 3.3 Example to use for LoRaWAN network ==
42.1	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
65.9	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.
42.1	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:

	172	)))
	173	* (((

61.1	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.
