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.

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.
661 -
662 -The firmware version released after 2024, Mar will use change back to use Json format. Detail please check changelog.

685 -When see this issue, below are the checklist:
686 -
687 -* 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.
688 -* 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]].
689 -* 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]].
690 -* Check if the device is attached to Carrier network but reject. (need to check with operator).
691 -* Check if the antenna is connected firmly.
692 -
693 -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.
