3.1	11	This configure instruction is for Dragino NB-IoT models with -CB or -CS suffix, for example DDS75-CB. These models use the same NB-IoT Module [[BG95-M2>>https://www.dropbox.com/sh/3ilyaswz4odgaru/AADR86cAgL9UGlmLuEH-UZgla?st=x1ry6v5j&dl=0]] 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.

3.1	18	To attache end nodes to NB-IoT or LTE-M Network, You need to:
1.1	19
3.1	20	1. Get a NB-IoT or LTE-M SIM card from Service Provider. (Not the same as the SIM card we use in mobile phone)
2.1	21	1. Power Off End Node ( See below for the power off/on position)
	22	1. Insert the SIM card to Sensor. ( See below for direction)
	23	1. Power On End Node
	24	1. [[Configure APN>>http://wiki.dragino.com/xwiki/bin/view/Main/How%20to%20configure%20APN%20in%20the%20node/]] in the sensor (AT+APN=<APN>), example AT+APN=iot.1nce.net

1.1	611
	612	User can use this feature for below purpose:
	613
2.1	614	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.
	615	1. Give more sampling data points.
	616	1. Increase reliable in transmission. For example. If user set
	617	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)
	618	1. AT+NOUD=24* ~/~/ The device uploads 24 sets of recorded data by default. Up to 32 sets of record data can be uploaded.
	619	1. AT+TDC=7200* ~/~/ Uplink every 2 hours.
	620	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.
1.1	621
2.1	622	== 5.2 Why the uplink JSON format is not standard? ==
1.1	623
	624	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.
	625
	626	The firmware version released after 2024, Mar will use change back to use Json format. Detail please check changelog.

1.1	633
	634	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.
	635
2.1	636	If end device successfully attached NB-IoT Network, User can normally see the signal strengh as below (between 0~~31)

1.1	643
2.1	644	(% class="lead" %)
1.1	645	When see this issue, below are the checklist:
	646
2.1	647	* 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.
	648	* 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]].
	649	* 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]].
	650	* Check if the device is attached to Carrier network but reject. (need to check with operator).
	651	* Check if the antenna is connected firmly.
1.1	652
2.1	653	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.
