601 -== 2.5 Datalog Feature ==
670 +When the two pieces are close to each other, the 2 wire output will be short or open (depending on the type), while if the two pieces are away from each other, the 2 wire output will be the opposite status. So we can use SN50_v3 interrupt interface to detect the status for the door or window.
602 602  
672 +(% style="color:blue" %)**~ Below is the installation example:**
603 603  
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.
674 +Fix one piece of the magnetic sensor to the door and connect the two pins to SN50_v3 as follows:
605 605  
676 +* (((
677 +One pin to SN50_v3's PA8 pin
678 +)))
679 +* (((
680 +The other pin to SN50_v3's VDD pin
681 +)))
606 606  
607 -=== 2.5.1 Ways to get datalog via LoRaWAN ===
683 +Install the other piece to the door. Find a place where the two pieces will be close to each other when the door is closed. For this particular magnetic sensor, when the door is closed, the output will be short, and PA8 will be at the VCC voltage.
608 608  
685 +Door sensors have two types: ** NC (Normal close)** and **NO (normal open)**. The connection for both type sensors are the same. But the decoding for payload are reverse, user need to modify this in the IoT Server decoder.
609 609  
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.
687 +When door sensor is shorted, there will extra power consumption in the circuit, the extra current is 3v3/R14 = 3v3/1Mohm = 3uA which can be ignored.
611 611  
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.

693 +The software by default uses the falling edge on the signal line as an interrupt. We need to modify it to accept both the rising edge (0v ~-~-> VCC , door close) and the falling edge (VCC ~-~-> 0v , door open) as the interrupt.

708 +==== 2.3.3.6 I2C Interface (SHT20 & SHT31) ====
633 633  
710 +The SDA and SCK are I2C interface lines. You can use these to connect to an I2C device and get the sensor data.
634 634  
635 -=== 2.5.3 Set Device Time ===
712 +We have made an example to show how to use the I2C interface to connect to the SHT20/ SHT31 Temperature and Humidity Sensor.
636 636  
714 +Notice: Different I2C sensors have different I2C commands set and initiate process, if user want to use other I2C sensors, User need to re-write the source code to support those sensors. SHT20/ SHT31 code in SN50_v3 will be a good reference.
637 637  
638 -User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
716 +Below is the connection to SHT20/ SHT31. The connection is as below:
639 639  
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).
641 641  
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.**
719 +[[image:image-20230513103633-3.png||height="448" width="716"]]
