Edwin Chen 2.1 20 The Dragino DS03A-LB is a (% style="color:blue" %)**LoRaWAN Door Sensor**(%%) for Internet of Things solution. It detects door open/close status and uplinks to IoT server via LoRaWAN network. user can see the door status, open duration, open counts in the IoT Server.
Edwin Chen 1.1 21 )))
22
23 (((
Edwin Chen 2.1 24 The LoRa wireless technology used in DS03A-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.
Edwin Chen 1.1 25 )))
26
27 (((
Edwin Chen 2.1 28 The DS03A-LB will send periodically data every 2 hours as well as for each door open/close action. It also counts the door open times and calculates the last door open duration. Users can also disable the uplink for each open/close event, instead, DS03A-LB can count each open event and uplink periodically.
Edwin Chen 1.1 29 )))
30

Edwin Chen 2.1 32 DS03A-LB supports (% style="color:blue" %)**Datalog Feature,**(%%) it can save the data when there is no LoRaWAN network and uplink when network recover.
Edwin Chen 1.1 33 )))
34
35 (((
Edwin Chen 2.1 36 DS03A-LB has the (% style="color:blue" %)**Open Alarm Feature**(%%), user can set this feature so the device will send an alarm if the door has been open for a certain time.
37
38 DS03A-LB is designed for outdoor use. It has a weatherproof enclosure and industrial level battery to work in low to high temperatures

Edwin Chen 2.1 169 The DS03A-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 DS03A-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

434
435
Edwin Chen 2.1 436 **Datalog Feature** is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, DS03A-LB will store the reading for future retrieving purposes.

439 === 2.5.1 Ways to get datalog via LoRaWAN ===
440
441
Edwin Chen 2.1 442 Set [[PNACKMD=1>>||anchor="H2.5.4DatalogUplinkpayloadA028FPORT3D329"]], DS03A-LB will wait for ACK for every uplink, when there is no LoRaWAN network,DS03A-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.
Edwin Chen 1.1 443
Edwin Chen 2.1 444 * a) DS03A-LB will do an ACK check for data records sending to make sure every data arrive server.
445 * b) DS03A-LB will send data in **CONFIRMED Mode** when PNACKMD=1, but DS03A-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 DS03A-LB gets a ACK, DS03A-LB will consider there is a network connection and resend all NONE-ACK Message.
Edwin Chen 1.1 446
Edwin Chen 2.1 447 Below is the typical case for the Datalog Feature (Set PNACKMD=1)

470 User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
471
Edwin Chen 2.1 472 Once DS03A-LB Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to DS03A-LB. If DS03A-LB fails to get the time from the server, DS03A-LB will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
Edwin Chen 1.1 473
Edwin Chen 2.1 474 (% 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 and loriot support but TTN 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 v2 if SYNCMOD=1.**
