639 +== 4.1 What is the usage of Multi Sampling and One Uplink? ==
640 +
641 +
642 +The NB series has the feature for Multi Sampling and one uplink. See one of them
643 +
644 +[[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]]
645 +
646 +User can use this feature for below purpose:
647 +
648 +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.
649 +1. Give more sampling data points.
650 +1. Increase reliable in transmission. For example. If user set
651 +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)
652 +1*. **AT+NOUD=24** ~/~/  The device uploads 24 sets of recorded data by default. Up to 32 sets of record data can be uploaded.
653 +1*. **AT+TDC=7200**  ~/~/ Uplink every 2 hours.
654 +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.
655 +
656 +
657 +== 4.2 Why the uplink JSON format is not standard? ==
658 +
659 +
660 +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.

667 +== 5.1 Checklist for debuging Network Connection issue. Signal Strenght:99 issue. ==
668 +
669 +
670 +There are many different providers provide NB-IoT service in the world. They might use different band, different APN & different operator configuration. Which makes connection to NB-IoT network is complicate.
671 +
672 +If end device successfully attached NB-IoT Network, User can normally see the signal strengh as below (between 0~~31)
673 +
674 +[[image:image-20240207002003-1.png]]
675 +
676 +
677 +If fail to attach network, it will shows signal 99. as below:
678 +
679 +[[image:image-20240207002129-2.png]]
680 +
681 +
682 +(% class="lead" %)
683 +When see this issue, below are the checklist:
684 +
685 +* Does your SIM card support NB-IoT network? If SIM card doesn't not specify support NB-IoT clearly, normally it doesn't support. You need to confirm with your operator.
686 +* Do you configure the correct APN? [[Check here for APN settings>>http://wiki.dragino.com/xwiki/bin/view/Main/General%20Configure%20to%20Connect%20to%20IoT%20server%20for%20-NB%20%26%20-NS%20NB-IoT%20models/#H2.1GeneralConfiguretoattachnetwork]].
687 +* Do you lock the frequency band? This is the most case we see. [[Explain and Instruction>>http://wiki.dragino.com/xwiki/bin/view/Main/General%20Configure%20to%20Connect%20to%20IoT%20server%20for%20-NB%20%26%20-NS%20NB-IoT%20models/#H2.2SpeedUpNetworkAttachtime]].
688 +* Check if the device is attached to Carrier network but reject. (need to check with operator).
689 +* Check if the antenna is connected firmly.
690 +
691 +If you have check all above and still fail. please send console log files (as many as possible) to [[support@dragino.com>>mailto:support@dragino.com]] so we can check.

709 +This issue might due to initiate issue for NB-IoT module. In this case, please try:
710 +
711 +1) Open Enclosure
712 +
713 +2) Power off device by pull out the power on Jumper
714 +
715 +3) Power on device by connect back the power jumper.
716 +
