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 133.1 639 == 4.1 What is the usage of Multi Sampling and One Uplink? ==
Edwin Chen 132.1 640
Xiaoling 145.2 641
Edwin Chen 133.1 642 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.
Xiaoling 148.2 654 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.
Edwin Chen 133.1 655
Edwin Chen 145.1 656 == 4.2 Why the uplink JSON format is not standard? ==
657
Xiaoling 148.2 658
Edwin Chen 145.1 659 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.
660
Edwin Chen 148.1 661 The firmware version released after 2024, Mar will use change back to use Json format. Detail please check changelog.

669
Xiaoling 145.2 670
Edwin Chen 132.1 671 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.
672
673 If end device successfully attached NB-IoT Network, User can normally see the signal strengh as below (between 0~~31)
674
675 [[image:image-20240207002003-1.png]]
676
677
678 If fail to attach network, it will shows signal 99. as below:

681
682
683 (% class="lead" %)
684 When see this issue, below are the checklist:
685
686 * 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.
687 * 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]].
688 * 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]].
689 * Check if the device is attached to Carrier network but reject. (need to check with operator).
690 * Check if the antenna is connected firmly.
691
692 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.

715
716 3) Power on device by connect back the power jumper.
