712 -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.

714 -**~ Below is the installation example:**
347 +== 2.5 Datalog Feature ==
715 715  
716 -Fix one piece of the magnetic sensor to the door and connect the two pins to SN50_v3 as follows:
717 717  
718 -* (((
719 -One pin to SN50_v3's PA8 pin
720 -)))
721 -* (((
722 -The other pin to SN50_v3's VDD pin

350 +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.
724 724  
725 -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.
726 726  
727 -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.
353 +=== 2.5.1 Ways to get datalog via LoRaWAN ===
728 728  
729 -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.

732 732  
733 -The above photos shows the two parts of the magnetic switch fitted to a door.
358 +* a) S31x-LB will do an ACK check for data records sending to make sure every data arrive server.
359 +* 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.
734 734  
735 -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.

755 755  
756 -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.
