	78	+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:
	79	+
	80	+* Support RS485 Interface
	81	+* with M12 5pin connector.
	82	+
	83	+Such model in GroPoint Profile is: **2625-N-T-x-M-M **(Where x is different depending on how many levels it detects).

78	78	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

	138	+== Uplink Payload Analyze ==
129	129
	140	+Uplink payloads have two types:
	141	+
	142	+* (((
	143	+Report temperature and humidity status normally: Use FPORT=2
	144	+)))
	145	+* (((
	146	+Other control commands: Use other FPORT fields.
	147	+)))
	148	+
	149	+The application server should parse the correct value based on FPORT settings.
	150	+
	151	+
	152	+== temperature and humidity Value, Uplink FPORT~=2 ==
	153	+
	154	+
	155	+GroPoint Air will send this uplink after Device Status once join the LoRaWAN network successfully. And GroPoint Air will:
	156	+
	157	+periodically send this uplink every 20 minutes, this interval can be changed.
	158	+
	159	+The drawing below shows the probe dimensions of the 2-8 segment probes, Temperature sen sor locations provided in table below:
	160	+
	161	+[[image:image-20220621093414-1.png||height="932" width="816"]]
	162	+
	163	+GroPoint Air's sensors come in six models:GPLP-2，GPLP-3，GPLP-4，GPLP-5，GPLP-6，GPLP-8.
	164	+
	165	+The amount of temperature and humidity is different for each model, so the payload of each model is different.
	166	+
	167	+Take GPLP-3 as an example：
	168	+
	169	+Uplink Payload totals 21 bytes.

130	130	Datacake IoT platform provides a human-friendly interface to show the sensor data, once we have sensor data in TTN V3, we can use Datacake to connect to TTN V3 and see the data in Datacake. Below are the steps:

132	132	**Step 1**: Link TTNv3 to Datacake [[https:~~/~~/docs.datacake.de/lorawan/lns/thethingsindustries#create-integration-on-tti>>url:https://docs.datacake.de/lorawan/lns/thethingsindustries#create-integration-on-tti]]
