150

151

152

The SN50v3-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 S31x-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

276

277

278

SN50v3 has different working mode for the connections of different type of sensors. This section describes these modes. Use can use the AT Command AT+MOD to set SN50v3 to different working modes.

For example:

**AT+MOD=2 ** ~/~/ will set the SN50v3 to work in MOD=2 distance mode which target to measure distance via Ultrasonic Sensor.

283

Each HX711 need to be calibrated before used. User need to do below two steps:

409

410

1. Zero calibration. Don't put anything on load cell and run **AT+WEIGRE** to calibrate to Zero gram.

411

1. Adjust calibration factor (default value 400): Put a known weight thing on load cell and run **AT+WEIGAP** to adjust the Calibration Factor.

412

1. (((

413

Remove the limit of plus or minus 5Kg in mode 5, and expand from 2 bytes to 4 bytes, the unit is g.(Since v1.8.0)

)))

For example:

**AT+WEIGAP =403.0**

Response: Weight is 401 g

421

422

Check the response of this command and adjust the value to match the real value for thing.

436

In this mode, the device will work in counting mode. It counts the interrupt on the interrupt pins and sends the count on TDC time.

437

438

Connection is as below. The PIR sensor is a count sensor, it will generate interrupt when people come close or go away. User can replace the PIR sensor with other counting sensors.

**Note:** LoRaWAN wireless transmission will infect the PIR sensor. Which cause the counting value increase +1 for every uplink. User can change PIR sensor or put sensor away of the LSN50 to avoid this happen.

== 2.5 Datalog Feature ==

602

603

604

Datalog Feature is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, S31x-LB will store the reading for future retrieving purposes.

605

606

607

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

608

609

610

Set [[PNACKMD=1>>||anchor="H2.5.4DatalogUplinkpayloadA028FPORT3D329"]], S31x-LB will wait for ACK for every uplink, when there is no LoRaWAN network,S31x-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.

611

612

* a) S31x-LB will do an ACK check for data records sending to make sure every data arrive server.

613

* b) S31x-LB will send data in **CONFIRMED Mode** when PNACKMD=1, but S31x-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 S31x-LB gets a ACK, S31x-LB will consider there is a network connection and resend all NONE-ACK messages.

614

615

Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)

616

617

631

632

So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25

633

=== 2.5.3 Set Device Time ===

636

637

638

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

639

640

Once S31x-LB Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to S31x-LB. If S31x-LB fails to get the time from the server, S31x-LB will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).

641

642

(% 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.**

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

673

674

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

675
