197

198

199

The PS-LB-NA 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 activate the PS-LB-NA. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

PS-LB-NA might connect to different kind of probes, 4~~20mA represent the full scale of the measuring range. So a 12mA output means different meaning for different probe.

**For example.**

379

380

User can set different probe model for above probes. So IoT server is able to se identical how it should parse the 4~~20mA or 0~~30v sensor value and get the correct value.

381

382

383

When connecting to current sensors sold by our company, you can convert current readings to corresponding values by simply configuring the [[AT+PROBE command>>||anchor="H3.3.4SettheProbeModel"]]. If you prefer not to configure this command on the sensor, you can uniformly handle the conversion in the payload decoder instead.

384

385

**Examples for decoder implementation:**

387

~1. For AT+PROBE=0005, add the following processing in your decoder:

561

=== 2.7.2 Set Device Time ===

562

563

564

There are two ways to set the device's time:

565

566

567

(% style="color:blue" %)**1. Through LoRaWAN MAC Command (Default settings)**

568

569

Users need to set SYNCMOD=1 to enable sync time via the MAC command.

570

571

Once PS-LB Joined the LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to CPL01. If CPL01 fails to get the time from the server, PS-LB will use the internal time and wait for the next time request ~[[[via Device Status (FPORT=5)>>||anchor="H2.3.1DeviceStatus2CFPORT3D5"]]].

572

573

574

(% style="color:red" %)**Note: LoRaWAN Server needs to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature.**

575

576

577

(% style="color:blue" %)**2. Manually Set Time**

578

579

Users need to set SYNCMOD=0 to manual time, otherwise, the user set time will be overwritten by the time set by the server.

580

581

582

=== 2.7.3 Poll sensor value ===

583

584

585

Users can poll sensor values based on timestamps. Below is the downlink command.

**Poll Message Flag**: 1: This message is a poll message reply.

632

633

* Poll Message Flag is set to 1.

634

635

* Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.

636

637

For example, in US915 band, the max payload for different DR is:

638

639

**a) DR0:** max is 11 bytes so one entry of data

640

641

**b) DR1:** max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)

642

643

**c) DR2:** total payload includes 11 entries of data

644

645

**d) DR3: **total payload includes 22 entries of data.

646

782

Note: The Internet pin of the old motherboard is a separate pin in the screw terminal, and the interrupt pin of the new motherboard(SIB V1.3) is the **GPIO_EXTI** pin.

Users need to configure this parameter according to the type of external probe. In this way, the server can decode according to this value, and convert the current value output by the sensor into water depth or pressure value.

1120

1121

(% style="color:blue" %)**AT Command: AT** **+PROBE**

AT+PROBE=aabb

When aa=00, it is the water depth mode, and the current is converted into the water depth value; bb is the probe at a depth of several meters.

1126

1127

When aa=01, it is the pressure mode, which converts the current into a pressure value;

1128

1129

bb represents which type of pressure sensor it is.
