== 2.1 How it works ==

178

179

180

The TC01/TC11-LB 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 press the button to activate the TC01/TC11-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

181

182

183

== 2.2 Quick guide to connect to LoRaWAN server (OTAA) ==

184

185

186

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.

187

188

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.

191

192

(% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from TC01/TC11-LB.

193

194

Each TC01/TC11-LB is shipped with a sticker with the default device EUI as below:

== 2.5 Datalog Feature ==

397

398

399

Datalog Feature is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, TC01/TC11-LB will store the reading for future retrieving purposes.

400

401

402

=== 2.5.1 Ways to get datalog via LoRaWAN ===

403

404

405

Set PNACKMD=1, TC01/TC11-LB will wait for ACK for every uplink, when there is no LoRaWAN network, TC01/TC11-LB will mark these records with non-ack messages and store the sensor data, and it will send all messages (10s interval) after the network recovery.

406

407

* (((

408

a) TC01/TC11-LB will do an ACK check for data records sending to make sure every data arrive server.

409

)))

410

* (((

411

b) TC01/TC11-LB will send data in **CONFIRMED Mode** when PNACKMD=1, but TC01/TC11-LB won't re-transmit the packet if it doesn't get ACK, it will just mark it as a NONE-ACK message. In a future uplink if TC01/TC11-LB gets a ACK, TC01/TC11-LB will consider there is a network connection and resend all NONE-ACK messages.

412

)))

414

=== 2.5.2 Unix TimeStamp ===

415

416

417

TC01/TC11-LB uses Unix TimeStamp format based on

431

432

433

User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.

434

435

Once TC01/TC11-LB Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to TC01/TC11-LB. If TC01/TC11-LB fails to get the time from the server, TC01/TC11-LB will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).

436

437

(% 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 SYNCMOD=1.**

**No ACK Message**: 1: This message means this payload is fromn Uplink Message which doesn't get ACK from the server before ( for **PNACKMD=1** feature)

469

470

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

471

472

* Poll Message Flag is set to 1.

473

474

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

475

476

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

477

478

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

479

480

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

481

482

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

483

484

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

485

486

If devise doesn't have any data in the polling time. Device will uplink 11 bytes of 0

**Example:**

If TC01/TC11-LB has below data inside Flash:
