675 +== 5.1 What is the usage of Multi Sampling and One Uplink? ==
676 +
677 +
678 +The NB series has the feature for Multi Sampling and one uplink. See one of them
679 +
680 +[[http:~~/~~/wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/SN50v3-NB_BN-IoT_Sensor_Node_User_Manual/#H2.5Multi-SamplingsandOneuplink>>http://wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/SN50v3-NB_BN-IoT_Sensor_Node_User_Manual/#H2.5Multi-SamplingsandOneuplink]]
681 +
682 +User can use this feature for below purpose:
683 +
684 +1. **Reduce power consumption**. The NB-IoT transmit power is much more higher than the sensor sampling power. To save battery life, we can sampling often and send in one uplink.
685 +1. Give more sampling data points.
686 +1. Increase reliable in transmission. For example. If user set
687 +1*. **AT+TR=1800** ~/~/ The unit is seconds, and the default is to record data once every 1800 seconds (30 minutes, the minimum can be set to 180 seconds)
688 +1*. **AT+NOUD=24** ~/~/  The device uploads 24 sets of recorded data by default. Up to 32 sets of record data can be uploaded.
689 +1*. **AT+TDC=7200**  ~/~/ Uplink every 2 hours.
690 +1*. this will mean each uplink will actually include the 6 uplink data (24 set data which cover 12 hours). So if device doesn't lost 6 continue data. There will not data lost.
691 +
692 +== 5.2 Why the uplink JSON format is not standard? ==
693 +
694 +
695 +The json format in uplink packet is not standard Json format. Below is the example. This is to make the payload as short as possible, due to NB-IoT transmit limition, a standard Json is not able to include 32 sets of sensors data with timestamp.
696 +
697 +The firmware version released after 2024, Mar will use change back to use Json format. Detail please check changelog.
