16 == 1.1 What is LC01 LoRaWAN Relay ==
17
18
19 The Dragino LC01 is a (% style="color:blue" %)**LoRaWAN Relay**(%%) for Internet of Things solution. It controls the device power switch via the IoT server downlink of the LoRaWAN wireless protocol.
20
21 It can be applied to (% style="color:blue" %)**smart agricultural irrigation, smart home, industrial automation and other industries**(%%).
22
23 The LoRa wireless technology used in the LC03 allows devices to send data at low rates and reach extremely long transmission distances. The technology provides ultra-long-range spread spectrum communication and high anti-interference capabilities while minimizing current consumption.
24
25 By default, LC01 has the function of detecting the access status of devices that need power. When the device that needs power is connected, it will automatically upload the data packet; when the device that needs power is disconnected, LC01 will also automatically upload the data packet.
26
27 LC01 (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
28
29 Each LC01 is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.

101 == 2.1 How it works ==
102
103
104 The LC03 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 LC03. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
105
106
107 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
108
109
110 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.
111
112 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.
113
114 [[image:image-20250507171046-7.png]]
115
116 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from LC03.

300
301 == 2.5 Datalog Feature ==
302
303
304 Datalog Feature is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, LC03 will store the reading for future retrieving purposes.
305
306
307 === 2.5.1 Ways to get datalog via LoRaWAN ===
308
309
310 With the platform downlink **07 01**, turn on the device to send None-ACK message function automatically, LC03 will wait for every upstream ACK, when there is no LoRaWAN network, LC03 will mark these records as non ack message and store the sensor data, and wait for the network to be restored (10s interval) to send all the messages.
311
312 * (((
313 a) LC03 will do an ACK check for data records sending to make sure every data arrive server.
314 )))
315 * (((
316 b) When automatic sending of None-ACK messages is enabled, the LC03 will send data in CONFIRMED mode, but if an ACK is not received, the LC03 will not resend the packet, it will only mark it as a NONE-ACK message. On subsequent uplinks, if the LC03 receives an ACK, the LC03 will consider the network connected and resend all NONE-ACK messages.
317 )))
318
319 === 2.5.2 Unix TimeStamp ===
320
321
322 LC03 uses Unix TimeStamp format based on
323
324 [[image:image-20250328173339-5.jpeg]]
325
326 User can get this time from link:  [[https:~~/~~/www.epochconverter.com/>>url:https://www.epochconverter.com/]] :
327
328 Below is the converter example
329
330 [[image:image-20250328173355-6.jpeg]]
331
332
333 So, we can use downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
334
335
336 === 2.5.3 Set Device Time ===
337
338
339 Users need to run downlink command (% style="color:blue" %)**28 01**(%%) to enable the synchronization time.
340
341 Once LC03 Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to LC03. If S31x-LB/LS fails to get the time from the server, LC03 will use the internal time and wait for next time request (The default time is once every 10 days.).
342
343 (% 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 v3 and loriot support but TTN V3 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 V3 v2 if when the automatic time synchronization function is turned on.**
344
345
346 === 2.5.4 Datalog Uplink payload (FPORT~=3) ===
347
348
349 The Datalog uplinks will use below payload format.

360
361 **No ACK Message**:  1: This message means this payload is fromn Uplink Message which doesn't get ACK from the server before ( for **Automatically send None-ACK** feature)
362
363 **DatalogReply**: 1: This message is a poll message reply.
364
365 * Poll Message Flag is set to 1.
366
367 * Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
368
369 For example, in US915 band, the max payload for different DR is:
370
371 **a) DR0:** max is 11 bytes so one entry of data
372
373 **b) DR1:** max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
374
375 **c) DR2:** total payload includes 11 entries of data
376
377 **d) DR3: **total payload includes 22 entries of data.
378
379 If devise doesn't have any data in the polling time. Device will uplink 11 bytes of 0   
380
381 **Example:**
382
383 If user sends below downlink command: 31681D4580681D6FB005
384
385 Where : Start time: 681D4580 = time 25/5/9 08:00:00

602
603
604 User need to set (% style="color:blue" %)**28 01**(%%) to enable sync time via MAC command.
605
606 Once LC03 Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to LC03. If LC03 fails to get the time from the server, LC03 will use the internal time and wait for next time request (default is 10 days).
607
608 (% 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 v3 and loriot support but TTN V3 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 V3 v2 if When the time synchronization function is enabled.**
609
610
611 (% style="color:#4f81bd" %)**Downlink Command: 0x28**
612
