300 == 2.1 How it works ==
301
302
303 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.

305
306 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
307
308
309 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.
310
311 [[image:image-20250419162538-1.png]]
312
313
314 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.
315
316
317 (% style="color:blue" %)**Step 1: Create a device in TTN with the OTAA keys from PS-LB/LS.**
318
319 Each PS-LB/LS is shipped with a sticker with the default device EUI as below:

459 === 2.3.3 Battery Info ===
460
461
462 Check the battery voltage for PS-LB/LS.
463
464 Ex1: 0x0B45 = 2885mV
465
466 Ex2: 0x0B49 = 2889mV
467
468
469 === 2.3.4 Probe Model ===
470
471
472 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. 
473
474 For example.
475

481
482 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.
483
484
485 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.
486
487 **Examples for decoder implementation:**
488
489 ~1. For AT+PROBE=0005, add the following processing in your decoder:
490
491 [[image:image-20250512144042-1.png]]
492
493 [[image:image-20250512144122-2.png]]
494
495 2. For AT+PROBE=0102, add the following processing in your decoder(Corresponding to the position shown in the above screenshot).
496
497 bytes[i]=0x01;bytes[1+i]=0x02;
498
499 bytes[2]=0x01;bytes[3]=0x02;
500
501
502 === 2.3.5 0~~20mA value (IDC_IN) ===
503
504
505 The output value from Pressure Probe, use together with Probe Model to get the pressure value or water level.
506
507 Example:
508
509 27AE(H) = 10158 (D)/1000 = 10.158mA.
510
511
512 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:
513
514 [[image:image-20230225154759-1.png||height="408" width="741"]]
515
516
517 === 2.3.6 0~~30V value (pin VDC_IN) ===
518
519
520 Measure the voltage value. The range is 0 to 30V.
521
522 Example:
523
524 138E(H) = 5006(D)/1000= 5.006V
525
526
527 === 2.3.7 IN1&IN2&INT pin ===
528
529
530 IN1 and IN2 are used as digital input pins.
531
532 Example:
533
534 09 (H): (0x09&0x08)>>3=1    IN1 pin is high level.
535
536 09 (H): (0x09&0x04)>>2=0    IN2 pin is low level.
537
538
539 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.
540
541 Example:
542
543 09 (H): (0x09&0x02)>>1=1    The level of the interrupt pin.
544
545 09 (H): 0x09&0x01=1              0x00: Normal uplink packet.
546
547 0x01: Interrupt Uplink Packet.

591
592 Step 1: Be sure that your device is programmed and properly connected to the network at this time.
593
594 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 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.
632
633
634 === 2.6.1 Unix TimeStamp ===
635
636
637 PS-LB uses Unix TimeStamp format based on
638
639 [[image:image-20250401163826-3.jpeg]]
640
641 Users can get this time from the link:  [[https:~~/~~/www.epochconverter.com/>>url:https://www.epochconverter.com/]] :
642
643 Below is the converter example:
644

646
647
648 === 2.6.2 Set Device Time ===
649
650
651 There are two ways to set the device's time:
652
653
654 ~1. Through LoRaWAN MAC Command (Default settings)
655
656 Users need to set SYNCMOD=1 to enable sync time via the MAC command.
657
658 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]]].
659
660 Note: LoRaWAN Server needs to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature.
661
662
663 2. Manually Set Time
664
665 Users need to set SYNCMOD=0 to manual time, otherwise, the user set time will be overwritten by the time set by the server.
666
667
668 === 2.6.3 Poll sensor value ===
669
670 Users can poll sensor values based on timestamps. Below is the downlink command.
671
672 (% border="1" cellspacing="3" style="background-color:#f2f2f2; width:470px" %)
673 |=(% colspan="4" style="width: 160px; background-color:#4F81BD;color:white" %)Downlink Command to poll Open/Close status (0x31)

676 Timestamp end
677 )))|(% style="background-color:#f2f2f2; width:163px" %)Uplink Interval
678
679 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.
680
681 For example, downlink command[[image:image-20250117104812-1.png]]
682
683 Is to check 2024/12/20 09:34:59 to 2024/12/20 14:34:59's data
684

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

1165 Downlink Command: 0x07
1166
1167 Format: Command Code (0x07) followed by 3 bytes.
1168
1169 The first byte is which power, the second and third bytes are the time to turn on.
1170
1171 * Example 1: Downlink Payload: 070101F4  ~-~-->  AT+3V3T=500
1172 * Example 2: Downlink Payload: 0701FFFF   ~-~-->  AT+3V3T=65535
1173 * Example 3: Downlink Payload: 070203E8  ~-~-->  AT+5VT=1000
1174 * Example 4: Downlink Payload: 07020000  ~-~-->  AT+5VT=0
1175 * Example 5: Downlink Payload: 070301F4  ~-~-->  AT+12VT=500
1176 * Example 6: Downlink Payload: 07030000  ~-~-->  AT+12VT=0
1177
1178 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.
1179
1180 Therefore, the corresponding downlink command is increased by one byte to five bytes.
1181
1182 Example:
1183
1184 * 120s=120000ms(D) =0x01D4C0(H), Downlink Payload: 07 01 01 D4 C0  ~-~-->  AT+3V3T=120000

1186 * 80s=80000ms(D) =0x013880(H), Downlink Payload: 07 03 01 38 80  ~-~-->  AT+12VT=80000

1416 Test the current values at the depth of different liquids and convert them to a linear scale.
1417 Replace its ratio with the ratio of water to current in the decoder.
1418
1419 Example:
1420
1421 Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
1422
1423 Calculate scale factor:
1424 Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
1425
1426 Calculation formula:
1427
1428 Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
1429
1430 Actual calculations:
1431
1432 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
