16 | == 1.1 What is NDS01 NB-IoT Door Sensor == | ||
17 | |||
18 | |||
19 | ((( | ||
20 | The Dragino NDS01 is a (% style="color:blue" %)**NB-IOT Door Sensor**(%%) for Internet of Things solution. It is used to (% style="color:blue" %)**detect the open/close event for door and uplink the event** (%%)to IoT server via NB-IoT network. | ||
21 | ))) | ||
22 | |||
23 | ((( | ||
24 | Besides open/close event, NDS01 also has an internal temperature and humidity sensor which can detect the temperature and humidity inside the sensor. | ||

26 | |||
27 | ((( | ||
28 | (% style="color:blue" %)**NarrowBand-Internet of Things (NB-IoT)**(%%) is a standards-based low power wide area (LPWA) technology developed to enable a wide range of new IoT devices and services. NB-IoT significantly improves the power consumption of user devices, system capacity and spectrum efficiency, especially in deep coverage. | ||

93 | = 2. Use NDS01 to communicate with IoT Server = | ||
94 | |||
95 | == 2.1 How it works == | ||
96 | |||
97 | |||
98 | The NDS01 is equipped with a NB-IoT module, the pre-loaded firmware in NDS01 will get environment data from sensors and send the value to local NB-IoT network via the NB-IoT module. The NB-IoT network will forward this value to IoT server via the protocol defined by NDS01. | ||
99 | |||
100 | The diagram below shows the working flow in default firmware of NDS01: | ||
101 | |||
102 | |||
103 | == 2.2 Configure the NDS01 == | ||
104 | |||
105 | === 2.2.1 Test Requirement === | ||
106 | |||
107 | |||
108 | To use NDS01 in your city, make sure meet below requirements: | ||
109 | |||
110 | * Your local operator has already distributed a NB-IoT Network there. | ||
111 | * The local NB-IoT network used the band that NDS01 supports. | ||
112 | * Your operator is able to distribute the data received in their NB-IoT network to your IoT server. | ||
113 | |||
114 | Below figure shows our testing structure.Here we have NB-IoT network coverage by China Mobile, the band they use is B8. The NDS01 will use (% style="color:red" %)**UDP(120.24.4.116:5601)** (%%)or (% style="color:red" %)**TCP(120.24.4.116:5600) **(%%)protocol to send data to IoT server. | ||

119 | |||
120 | === 2.2.1 Insert SIM card === | ||
121 | |||
122 | |||
123 | Insert the NB-IoT Card get from your provider. | ||
124 | |||
125 | User need to take out the NB-IoT module and insert the SIM card like below: | ||
126 | |||
127 | |||
128 | [[image:1668224846067-276.png]] | ||
129 | |||
130 | |||
131 | === 2.2.3 Configure NDS01 === | ||
132 | |||
133 | |||
134 | User need to configure NDS01 via serial port to set the **Server Address** / **Uplink Topic** to define where and how-to uplink packets. NDS01 support AT Commands, user can use a USB to TTL adapter to connect to NDS01 and use AT Commands to configure it, NDS01 needs to be in the wake-up state when using AT commands,as below. | ||

443 | |||
444 | (1) In the self-check mode (the default is the self-check mode when power on for the first time), the state change of the tamper switch does not trigger an alarm; | ||
445 | |||
446 | (2) In normal working mode, the state change of the tamper switch triggers an alarm; | ||
447 | |||
448 | (3) In silent mode (the default is non-silent mode when power on for the first time), the buzzer is silent. | ||
449 | |||
450 | |||

473 | |||
474 | (2) Enter the normal working mode (the tamper switch is closed for more than 5s or the door sensor is locked for more than 5s), the buzzer will sound for 1500ms; | ||
475 | |||
476 | (3) After entering the normal working mode, the tamper switch does not close, the buzzer sounds for 30s, the tamper switch is closed, and the buzzer sounds 1 time; | ||
