9.2	29
121.3	30
118.1	31	The Dragino D2x-LB is a (% style="color:blue" %)LoRaWAN Temperature Sensor(%%) for Internet of Things solution. D2x-LB has 1 ~~ 3 temperature probes. D2x-LB will convert the Temperature reading to LoRaWAN wireless data and send to IoT platform via LoRaWAN gateway.
72.5	32
116.1	33	The LoRa wireless technology used in D2x-LB allows device 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.
6.2	34
118.1	35	The temperature sensor used in D2x-LB can (% style="color:blue" %)measure -55°C ~~ 125°C with accuracy ±0.5°C (max ±2.0 °C)(%%).
6.2	36
118.1	37	D2x-LB supports (% style="color:blue" %)temperature alarm feature(%%), user can set temperature alarm for instant notice. D2x-LB supports Datalog feature, it can save the data when there is no LoRaWAN network and uplink when network recover.
63.1	38
116.1	39	D2x-LB has max 3 probes which measure maximum 3 temperature points.
63.1	40
118.1	41	D2x-LB (% style="color:blue" %)supports BLE configure(%%) and (% style="color:blue" %)wireless OTA update(%%) which make user easy to use.

67.1	217	The D2x-LB is configured as (% style="color:#037691" %)LoRaWAN OTAA Class A(%%) mode by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and press the button to activate the D2x-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

	224
	225	The LPS8V2 is already set to connected to [[TTN network >>url:https://console.cloud.thethings.network/]], so what we need to now is configure the TTN server.

	486
84.2	487
81.1	488	Datalog Feature is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, D2x-LB will store the reading for future retrieving purposes.
	489
	490
	491	=== 2.5.1 Ways to get datalog via LoRaWAN ===
	492
84.2	493
98.9	494	Set [[PNACKMD=1>>\|\|anchor="H2.5.4DatalogUplinkpayloadA028FPORT3D329"]], D2x-LB will wait for ACK for every uplink, when there is no LoRaWAN network,D2x-LB will mark these records with non-ack messages and store the sensor data, and it will send all messages (10s interval) after the network recovery.
81.1	495
	496	* a) D2x-LB will do an ACK check for data records sending to make sure every data arrive server.
	497	* b) D2x-LB will send data in CONFIRMED Mode when PNACKMD=1, but D2x-LB won't re-transmit the packet if it doesn't get ACK, it will just mark it as a NONE-ACK message. In a future uplink if D2x-LB gets a ACK, D2x-LB will consider there is a network connection and resend all NONE-ACK Message.
	498

81.1	524
	525	Once D2x-LB Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to D2x-LB. If D2x-LB fails to get the time from the server, D2x-LB will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
	526
98.12	527	(% style="color:red" %)Note: LoRaWAN Server need to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature, Chirpstack,TTN V3 v3 and loriot support but TTN V3 v2 doesn't support. If server doesn't support this command, it will through away uplink packet with this command, so user will lose the packet with time request for TTN V3 v2 if SYNCMOD=1.
