57.2	130	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:
	131
	132	* Support RS485 Interface
	133	* with M12 5pin connector.
	134
65.5	135	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).

	137
64.2	138	== 3.2 Connect to LoRaWAN Network? ==
57.2	139
42.1	140	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
	141
	142
64.2	143	== 3.3 Example to use for LoRaWAN network ==
42.1	144
	145	This section shows an example of how to join the TTN V3 LoRaWAN IoT server. Usages with other LoRaWAN IoT servers are similar.
	146
65.9	147	* 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	148
