119
120
121 The LC01 is configured  as (% style="color:#037691" %)**LoRaWAN OTAA Class C**(%%) 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 LC01. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 1 hour.

125
126
127 The following network diagram shows how LC01 communicates with a LoRaWAN Network Server,  for example [[TTN v3 LoRaWAN Network>>url:https://console.cloud.thethings.network/]]. We use the [[LPS8N>>https://www.dragino.com/products/lora-lorawan-gateway/item/200-lps8n.html]]  as a LoRaWAN gateway in this example and ThingsEye as the IoT platform.

193
194
195 (% style="color:blue" %)**Step 2:**(%%) Add decoder.
196
197 LoRaWAN uplink and downlink payloads are encoded. To understand the data, you need a small script to decode them. We use a JavaScript function for this. It is called a payload formatter. It reads the payload and extracts useful information, such as relay status, event type, and timestamp. We have written a JavaScript function to decode uplinks from the LC01 device.
198
199
200 To add an uplink payload formatter code to The Things Stack, follow the steps below:
201
202 * Go to your LC01 device page and click Payload formatters.
203 * Click, Uplink.
204 * Select ‘Custom Javascript formatter’ from the ‘Formatter type’ drop-down list.
205 * Now copy the Uplink Formatter code from here: [[dragino-end-node-decoder/LC01/LC01_V1.0.0_TTN_Decoder.txt at main · dragino/dragino-end-node-decoder · GitHub>>url:https://github.com/dragino/dragino-end-node-decoder/blob/main/LC01/LC01_V1.0.0_TTN_Decoder.txt]]
206 * Then paste it in the ‘Formatter code’ box:
207
208 [[image:image-20250510090425-4.png||height="502" width="1080"]]
209
210
211 You can now test the formatter code with a sample payload.
212
213 * Enter 00 00 00 06 03 00 in the ‘Byte payload’ box.
214 * Change the FPort to 2 (because our payload formatter only accepts uplinks  from FPort 2).
215 * Click the ‘Test decoder’ button.
216
217 The payload will be decoded into the following JSON object and shown in the 'Decoded test payload' box.
218
219 To save the payload formatter, click the ‘Save changes’ button.
220
221 [[image:image-20250510090555-5.png||height="545" width="1071"]]
222
223
224 After applying the uplink payload formatter, you can see that all uplink payloads shown in the Live Data section are decoded into fields.
225
226
227 (% style="color:blue" %)**Step 3:**(%%) Activate on LC01
228
229 Press the reset button once to activate the LC01.

340
341 == 2.4 Payload Decoder ==
342
343
344 In The Things Stack, you can add a custom payload decoder to convert the raw payload into human-readable fields.
345
346 To do this go to: (% style="color:#037691" %)**Applications ~-~-> Payload Formats ~-~-> Custom ~-~-> Decoder**(%%) and add the decoder code from the following link:
347
348 [[https:~~/~~/github.com/dragino/dragino-end-node-decoder/tree/main/LC01>>https://github.com/dragino/dragino-end-node-decoder/tree/main/LC01]]
349
350
351 == 2.5 Datalog Feature ==
352
353
354 The Datalog feature ensures that the IoT server can receive all sampled data from the sensor, even if the LoRaWAN network is temporarily unavailable. For each sampling event, the LC01 stores the reading for future retrieval.
355
356
357 === 2.5.1 Retrieving Datalog via LoRaWAN ===
358
359
360 Using the platform downlink 07 01, you can enable the device to automatically send **non-ACK** messages. Once enabled, the LC01 will wait for an acknowledgment (ACK) for every uplink. If there is no LoRaWAN network available, LC01 will mark these records as non-ACK messages, store the sensor data, and continue checking for network availability (at 10-second intervals) to resend all stored messages once the network is restored.
361
362 * (((
363 a) LC01 performs an ACK check for each data record to ensure it successfully reaches the server.
364 )))
365 * (((
366 b) When automatic sending of non-ACK messages is enabled, the LC01 transmits data in **CONFIRMED** mode. If an ACK is not received, it does not resend the packet; instead, it marks it as a **non-ACK** message. During subsequent uplinks, if the LC01 receives an ACK, it considers the network restored and will resend all stored non-ACK messages.
367 )))
368
369 === 2.5.2 Unix TimeStamp ===
370
371
372 LC01 uses Unix Timestamp format based on the following table:
373
374 [[image:image-20250328173339-5.jpeg]]
375
376 You can get the Unix epoch time from this link:  [[https:~~/~~/www.epochconverter.com/>>url:https://www.epochconverter.com/]] :
377
378 Below is the Unix epoch time to Hex conversion example:
379
380 [[image:image-20250328173355-6.jpeg]]
381
382
383 So, you can use downlink 30**60137afd**00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
384
385
386 === 2.5.3 Set Device Time ===
387
388
389 You need to run downlink command 28 01 to enable time synchronization.
390
391 Once the LC01 joins the LoRaWAN network, it will send the MAC command **DeviceTimeReq**, and the server will reply with **DeviceTimeAns** to provide the current time to the LC01. If the LC01 fails to receive the time from the server, it will use its internal time and wait for the next time request. //(By default, this occurs once every 10 days.)//
392
393 {{info}}
394 The LoRaWAN server must support LoRaWAN v1.0.3 (MAC v1.0.3) or higher to use this MAC command feature. ChirpStack, The Things Stack v3, and Loriot support it, but The Things Stack v2 does not. If the server does not support this command, it will discard the uplink packet containing it. As a result, the user will lose the time request packet when the automatic time synchronization function is enabled on TTN v2.

421 * Each data entry is 7 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
422
423
424
425 For example, in US915 band, the max payload for different DR is:
426
427 **a) DR0:** max is 11 bytes so one entry of data
428
429 **b) DR1:** max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
430
431 **c) DR2:** total payload includes 11 entries of data
432
433 **d) DR3: **total payload includes 22 entries of data.
434
435 If devise doesn't have any data in the polling time. Device will uplink 7 bytes of 0   
436
437
438 **Example:**
439
440 If user sends below downlink command: 31681D4580681D6FB005
441
442 Where : Start time: 681D4580 = time 25/5/9 08:00:00
443
444 Stop time: 681D6FB0 = time 25/5/9 11:00:00
445
446
447 **LC01 will uplink this payload.**
