300
301 == 2.1 How it works ==
302
303
304 The PS-LB/LS is configured as 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/LS. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

308
309
310 Following is an example for how to join the [[TTN v3 LoRaWAN Network>>url:https://console.cloud.thethings.network/]]. Below is the network structure; we use the [[LPS8v2>>url:https://www.dragino.com/products/lora-lorawan-gateway/item/228-lps8v2.html]] as a LoRaWAN gateway in this example.
311
312 [[image:image-20250419162538-1.png]]
313
314
315 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.
316
317
318 (% style="color:blue" %)**Step 1: Create a device in TTN with the OTAA keys from PS-LB/LS.**
319
320 Each PS-LB/LS is shipped with a sticker with the default device EUI as below:

460 === 2.3.3 Battery Info ===
461
462
463 Check the battery voltage for PS-LB/LS.
464
465 Ex1: 0x0B45 = 2885mV
466
467 Ex2: 0x0B49 = 2889mV
468
469
470 === 2.3.4 Probe Model ===
471
472
473 PS-LB/LS has different kind of probe, 4~~20mA represent the full scale of the measuring range. So a 12mA output means different meaning for different probe. 
474
475 For example.
476

482
483 The probe model field provides the convenient for server to identical how it should parse the 4~~20mA sensor value and get the correct value.
484
485
486 When connecting to current sensors sold by our company, you can convert current readings to corresponding values by simply configuring the [[AT+PROBE>>||anchor="H3.3.4SettheProbeModel"]] command. If you prefer not to configure this command on the sensor, you can uniformly handle the conversion in the payload decoder instead.
487
488 **Examples for decoder implementation:**
489
490 ~1. For AT+PROBE=0005, add the following processing in your decoder:
491
492 [[image:image-20250512144042-1.png]]
493
494 [[image:image-20250512144122-2.png]]
495
496 2. For AT+PROBE=0102, add the following processing in your decoder(Corresponding to the position shown in the above screenshot).
497
498 bytes[i]=0x01;bytes[1+i]=0x02;
499
500 bytes[2]=0x01;bytes[3]=0x02;
501
502
503 === 2.3.5 0~~20mA value (IDC_IN) ===
504
505
506 The output value from Pressure Probe, use together with Probe Model to get the pressure value or water level.
507
508 Example:
509
510 27AE(H) = 10158 (D)/1000 = 10.158mA.
511
512
513 Instead of pressure probe, User can also connect a general 4~~20mA in this port to support different types of 4~~20mA sensors. below is the connection example:
514
515 [[image:image-20230225154759-1.png||height="408" width="741"]]
516
517
518 === 2.3.6 0~~30V value (pin VDC_IN) ===
519
520
521 Measure the voltage value. The range is 0 to 30V.
522
523 Example:
524
525 138E(H) = 5006(D)/1000= 5.006V
526
527
528 === 2.3.7 IN1&IN2&INT pin ===
529
530
531 IN1 and IN2 are used as digital input pins.
532
533 Example:
534
535 09 (H): (0x09&0x08)>>3=1    IN1 pin is high level.
536
537 09 (H): (0x09&0x04)>>2=0    IN2 pin is low level.
538
539
540 This data field shows if this packet is generated by Interrupt Pin or not. [[Click here>>||anchor="H3.3.2SetInterruptMode"]] for the hardware and software set up. Note: The Internet Pin is a separate pin in the screw terminal.
541
542 Example:
543
544 09 (H): (0x09&0x02)>>1=1    The level of the interrupt pin.
545
546 09 (H): 0x09&0x01=1              0x00: Normal uplink packet.
547
548 0x01: Interrupt Uplink Packet.

592
593 Step 1: Be sure that your device is programmed and properly connected to the network at this time.
594
595 Step 2: To configure the Application to forward data to DATACAKE you will need to add integration. To add the DATACAKE integration, perform the following steps:

631
632 When a user wants to retrieve sensor value, he can send a poll command from the IoT platform to ask the sensor to send value in the required time slot.
633
634
635 === 2.6.1 Unix TimeStamp ===
636
637
638 PS-LB uses Unix TimeStamp format based on
639
640 [[image:image-20250401163826-3.jpeg]]
641
642 Users can get this time from the link:  [[https:~~/~~/www.epochconverter.com/>>url:https://www.epochconverter.com/]] :
643
644 Below is the converter example:
645

647
648
649 === 2.6.2 Set Device Time ===
650
651
652 There are two ways to set the device's time:
653
654
655 ~1. Through LoRaWAN MAC Command (Default settings)
656
657 Users need to set SYNCMOD=1 to enable sync time via the MAC command.
658
659 Once CPL01 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, CPL01 will use the internal time and wait for the next time request ~[[[via Device Status (FPORT=5)>>url:http://wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/CPL01%20LoRaWAN%20Outdoor%20PulseContact%20%20Sensor%20Manual/#H2.3.1DeviceStatus2CFPORT3D5]]].
660
661 Note: LoRaWAN Server needs to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature.
662
663
664 2. Manually Set Time
665
666 Users need to set SYNCMOD=0 to manual time, otherwise, the user set time will be overwritten by the time set by the server.
667
668
669 === 2.6.3 Poll sensor value ===
670
671 Users can poll sensor values based on timestamps. Below is the downlink command.
672
673 (% border="1" cellspacing="3" style="background-color:#f2f2f2; width:470px" %)
674 |=(% colspan="4" style="width: 160px; background-color:#4F81BD;color:white" %)Downlink Command to poll Open/Close status (0x31)

677 Timestamp end
678 )))|(% style="background-color:#f2f2f2; width:163px" %)Uplink Interval
679
680 Timestamp start and Timestamp end-use Unix TimeStamp format as mentioned above. Devices will reply with all data logs during this period, using the uplink interval.
681
682 For example, downlink command[[image:image-20250117104812-1.png]]
683
684 Is to check 2024/12/20 09:34:59 to 2024/12/20 14:34:59's data
685
686 Uplink Internal =5s，means PS-LB will send one packet every 5s. range 5~~255s.

716
717 Poll Message Flag: 1: This message is a poll message reply.
718
719 * Poll Message Flag is set to 1.
720
721 * Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
722
723 For example, in US915 band, the max payload for different DR is:
724
725 a) DR0: max is 11 bytes so one entry of data
726
727 b) DR1: max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
728
729 c) DR2: total payload includes 11 entries of data
730
731 d) DR3: total payload includes 22 entries of data.
732
733 If devise doesn't have any data in the polling time. Device will uplink 11 bytes of 0   
734
735 Example:
736
737 If PS-LB-NA has below data inside Flash:
738

1166 Downlink Command: 0x07
1167
1168 Format: Command Code (0x07) followed by 3 bytes.
1169
1170 The first byte is which power, the second and third bytes are the time to turn on.
1171
1172 * Example 1: Downlink Payload: 070101F4  ~-~-->  AT+3V3T=500
1173 * Example 2: Downlink Payload: 0701FFFF   ~-~-->  AT+3V3T=65535
1174 * Example 3: Downlink Payload: 070203E8  ~-~-->  AT+5VT=1000
1175 * Example 4: Downlink Payload: 07020000  ~-~-->  AT+5VT=0
1176 * Example 5: Downlink Payload: 070301F4  ~-~-->  AT+12VT=500
1177 * Example 6: Downlink Payload: 07030000  ~-~-->  AT+12VT=0
1178
1179 Note: Before v1.2, the maximum settable time of 3V3T, 5VT and 12VT is 65535 milliseconds. After v1.2, the maximum settable time of 3V3T, 5VT and 12VT is 180 seconds.
1180
1181 Therefore, the corresponding downlink command is increased by one byte to five bytes.
1182
1183 Example:
1184
1185 * 120s=120000ms(D) =0x01D4C0(H), Downlink Payload: 07 01 01 D4 C0  ~-~-->  AT+3V3T=120000

1187 * 80s=80000ms(D) =0x013880(H), Downlink Payload: 07 03 01 38 80  ~-~-->  AT+12VT=80000

1417 Test the current values at the depth of different liquids and convert them to a linear scale.
1418 Replace its ratio with the ratio of water to current in the decoder.
1419
1420 Example:
1421
1422 Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
1423
1424 Calculate scale factor:
1425 Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
1426
1427 Calculation formula:
1428
1429 Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
1430
1431 Actual calculations:
1432
1433 Use this formula to calculate the value corresponding to the current at a depth of 1.5 meters: (6.918-5.035)/1.86470588235294+0.51=1.519810726
