Edwin Chen 1.1 14 This configure instruction is for Dragino NB-IoT models with -NB or -NS suffix, for example DDS75-NB. These models use the same NB-IoT Module **[[BC660K-GL>>https://www.quectel.com/product/lpwa-bc660k-gl-nb2]]** and has the same software structure. The have the same configure instruction to different IoT servers. Use can follow the instruction here to see how to configure to connect to those servers.

Edwin Chen 54.1 22 To attache NB-IoT sensors to NB-IoT Network, You need to:
23
24 1. Get a NB-IoT SIM card from Service Provider. (Not the same as the SIM card we use in mobile phone)
Edwin Chen 137.1 25 1. Power Off End Node ( See below for the power off/on position)
26 1. Insert the SIM card to Sensor. ( See below for direction)
27 1. Power On End Node

Edwin Chen 132.1 631
Edwin Chen 133.1 632 == 4.1 What is the usage of Multi Sampling and One Uplink? ==
Edwin Chen 132.1 633
Edwin Chen 133.1 634 The NB series has the feature for Multi Sampling and one uplink. See one of them
635
636 [[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]]
637
638 User can use this feature for below purpose:
639
640 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.
641 1. Give more sampling data points.
642 1. Increase reliable in transmission. For example. If user set
643 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)
644 1*. **AT+NOUD=24** ~/~/  The device uploads 24 sets of recorded data by default. Up to 32 sets of record data can be uploaded.
645 1*. **AT+TDC=7200**  ~/~/ Uplink every 2 hours.
646 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.

650 == 5.1 Checklist for debuging Network Connection issue. Signal Strenght:99 issue. ==
651
Edwin Chen 132.1 652 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.
653
654 If end device successfully attached NB-IoT Network, User can normally see the signal strengh as below (between 0~~31)
655
656 [[image:image-20240207002003-1.png]]
657
658
659 If fail to attach network, it will shows signal 99. as below:
660
661 [[image:image-20240207002129-2.png]]
662
663
664 (% class="lead" %)
665 When see this issue, below are the checklist:
666
667 * 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.
668 * 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]].
669 * 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]].
670 * Check if the device is attached to Carrier network but reject. (need to check with operator).
671 * Check if the antenna is connected firmly.
672
673 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.

690 This issue might due to initiate issue for NB-IoT module. In this case, please try:
691
692 1) Open Enclosure
693
694 2) Power off device by pull out the power on Jumper
695
696 3) Power on device by connect back the power jumper.
697
698 4) push reset button.

717
Mengting Qiu 142.1 718 When the MCU is communicating with the NB-IoT module, the MCU response of AT Command will become slower, it might takes several seconds to response.
