24 == 1.1 ​ What is CPN01 NB-IoT Pulse/Contact Sensor ==
25
26
27 (((
28 The Dragino CPN01 is an (% style="color:blue" %)**NB-IoT Dry Contact Sensor**(%%). It detects open/close status and uplinks the info to IoT server via NB-IoT network. User can see the (% style="color:blue" %)**dry contact status, open time, and open counts**(%%) in the IoT Server.
29 )))
30
31 (((
32 The CPN01 will send periodically data every day as well as for each dry contact action. It also counts the contact open times and calculates the last open duration. Users can also disable the uplink for each Open/Close event, instead, device can count each open event and uplink periodically.
33 )))
34
35 (((
36 CPN01 has** (% style="color:blue" %)Open-Alarm feature(%%)**, user can set this feature so CPN01 will send an alarm if the contact has been open exceeds a certain time.
37 )))
38
39 (((
40 CPN01 is designed for outdoor use. It has a weatherproof enclosure and industrial-level battery to work in low to high temperatures.
41 )))
42
43 (((
44 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.
45 \\CPN01 supports different uplink methods including (% style="color:blue" %)**TCP, MQTT, UDP, and CoAP**(%%) for different application requirements.
46 \\CPN01 is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), It is designed for long-term use of up to 5 years. (Actually Battery life depends on the use environment, update period & uplink method)
47 \\To use CPN01, user needs to check if there is NB-IoT coverage in the field and with the Nb-IoT bands that CPN01 supports. If local operator support it, user needs to get a (% style="color:blue" %)**NB-IoT SIM card**(%%) from the operator and install into CPN01 to get NB-IoT network connection.

156 == 2.1  How it works ==
157
158
159 The CPN01 is equipped with an NB-IoT module, the pre-loaded firmware in CPN01 will get (% style="color:blue" %)**Open/Close Event or Count**(%%) from sensor and send the value to the NB-IoT network. The NB-IoT network will forward this value to IoT server via the protocol defined by CPN01.
160
161 The diagram below shows the working flow in the default firmware of CPN01:

166 == 2.2 ​ Configure CPN01 ==
167
168 === 2.2.1 Test Requirement ===
169
170
171 To use CPN01 in your city, make sure to meet below requirements:
172
173 * Your local operator has already distributed an NB-IoT Network.
174 * The local NB-IoT network used the band that CPN01 supports.
175 * Your operator is able to distribute the data received in their NB-IoT network to your IoT server.
176
177 Below figure shows our testing structure. Here we have NB-IoT network coverage by China Mobile, the band they use is B8.  The CPN01 will use** (% style="color:red" %)CoAP(120.24.4.116:5683)(%%)** or raw (% style="color:red" %)**UDP(120.24.4.116:5601) **(%%)or (% style="color:red" %)**MQTT(120.24.4.116:1883) **(%%)or (% style="color:red" %)**TCP(120.24.4.116:5600)protocol**(%%) to send data to the test server.

190
191
192 === 2.2.3 Connect USB – TTL to CPN01 and configure it ===
193
194
195 User need to configure CPN01 via serial port to set the (% style="color:red" %)**Server Address** / **Uplink Topic**(%%) to define where and how-to uplink packets. CPN01 support AT Commands, user can use a USB to TTL adapter to connect to CPN01 and use AT Commands to configure it, as below.

430
431
432 The calculate flag is a user defined field, IoT server can use this filed to handle different meters with different pulse factors. For example, if there are 100 water meters, meter 1~~50 are 1 liter/pulse and meter 51 ~~ 100 has 1.5 liter/pulse.
433
434 User can set calculate flag to 1 for meter 1~~50 and 2 for meter 51 ~~ 100, So IoT Server can use this field for calculation.

513
514
515 The CPN01 has an internal LED which is to show the status of different states.
516
517 * When the device starts normally, the LED will light up for 1 second.
518 * After CPN01 join NB-IoT network. The LED will be ON for 3 seconds.
519 * For each uplink probe, LED will be on for 500ms.
