112 +
113 +
114 +**2.  Use CPN01 to communicate with IoT Server**
115 +
116 +**2.1  How it works**
117 +
118 +The CPN01 is equipped with a NB-IoT module, the pre-loaded firmware in CPN01 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 CPN01.
119 +
120 +The diagram below shows the working flow in default firmware of CPN01:
121 +
122 +[[image:file:///C:\Users\ADMINI~~1\AppData\Local\Temp\msohtmlclip1\01\clip_image005.png||alt="说明: image-20220708101605-2.png"]]
123 +
124 +**2.2 ​ Configure the CPN01**
125 +
126 +**2.2.1 Test Requirement**
127 +
128 +To use CPN01 in your city, make sure meet below requirements:
129 +
130 +* Your local operator has already distributed a NB-IoT Network there.
131 +* The local NB-IoT network used the band that CPN01 supports.
132 +* Your operator is able to distribute the data received in their NB-IoT network to your IoT server.
133 +
134 +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 CoAP(120.24.4.116:5683) or raw UDP(120.24.4.116:5601) or MQTT(120.24.4.116:1883)or TCP(120.24.4.116:5600)protocol to send data to the test server
135 +
136 + ​
137 +
138 +**2.2.2 Insert SIM card**
139 +
140 +Insert the NB-IoT Card get from your provider.
141 +
142 +User need to take out the NB-IoT module and insert the SIM card like below:
143 +
144 +[[image:file:///C:\Users\ADMINI~~1\AppData\Local\Temp\msohtmlclip1\01\clip_image006.png||alt="说明: 1657249468462-536.png"]] ​
145 +
146 +**2.2.3 Connect USB – TTL to CPN01 to configure it**
147 +
148 +User need to configure CPN01 via serial port to set the **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.
149 +
150 +**Connection:**
151 +
152 + USB TTL GND <~-~-~-~-> GND
153 +
154 + USB TTL TXD <~-~-~-~-> UART_RXD
155 +
156 + USB TTL RXD <~-~-~-~-> UART_TXD
157 +
158 +In the PC, use below serial tool settings:
159 +
160 +* Baud:  **9600**
161 +* Data bits:** 8**
162 +* Stop bits: **1**
163 +* Parity:  **None**
164 +* Flow Control: **None**
165 +
166 +Make sure the switch is in FLASH position, then power on device by connecting the jumper on CPN01. CPN01 will output system info once power on as below, we can enter the **password: 12345678** to access AT Command input.

503 +
504 +**2.16  ​Battery Analysis**
505 +
506 +**2.16.1  ​Battery Type**
507 +
508 +The CPN01 battery is a combination of an 8500mAh Li/SOCI2 Battery and a Super Capacitor. The battery is none-rechargeable battery type with a low discharge rate (<2% per year). This type of battery is commonly used in IoT devices such as water meter.
509 +
510 +The battery is designed to last for several years depends on the actually use environment and update interval. 
511 +
512 +The battery related documents as below:
513 +
514 +* [[Battery Dimension>>url:http://www.dragino.com/downloads/index.php?dir=datasheet/Battery/ER26500/]]
515 +* [[Lithium-Thionyl Chloride Battery datasheet>>url:http://www.dragino.com/downloads/index.php?dir=datasheet/Battery/ER26500/]]
516 +* [[Lithium-ion Battery-Capacitor datasheet>>url:http://www.dragino.com/downloads/index.php?dir=datasheet/Battery/ER26500/]]

519 +
520 +**2.16.2  Power consumption Analyze**
521 +
522 +Dragino battery powered product are all runs in Low Power mode. We have an update battery calculator which base on the measurement of the real device. User can use this calculator to check the battery life and calculate the battery life if want to use different transmit interval.
523 +
524 +Instruction to use as below:
525 +
526 +**Step 1:  **Downlink the up-to-date DRAGINO_Battery_Life_Prediction_Table.xlsx from: [[https:~~/~~/www.dragino.com/downloads/index.php?dir=LoRa_End_Node/Battery_Analyze/>>url:https://www.dragino.com/downloads/index.php?dir=LoRa_End_Node/Battery_Analyze/]]
527 +
528 +**Step 2: ** Open it and choose
529 +
530 +* Product Model
531 +* Uplink Interval
532 +* Working Mode
533 +
534 +And the Life expectation in difference case will be shown on the right.
535 +

537 +
538 +**2.16.3  ​Battery Note**
539 +
540 +The Li-SICO battery is designed for small current / long period application. It is not good to use a high current, short period transmit method. The recommended minimum period for use of this battery is 5 minutes. If you use a shorter period time to transmit LoRa, then the battery life may be decreased.
541 +
542 +**2.16.4  Replace the battery**
543 +
544 +The default battery pack of CPN01 includes a ER26500 plus super capacitor. If user can't find this pack locally, they can find ER26500 or equivalence without the SPC1520 capacitor, which will also work in most case. The SPC can enlarge the battery life for high frequency use (update period below 5 minutes).
545 +
546 +**3. ​ Access NB-IoT Module**
547 +
548 +Users can directly access the AT command set of the NB-IoT module.
549 +

642 +
643 +Please see this link for how to upgrade:  [[http:~~/~~/wiki.dragino.com/xwiki/bin/view/Main/Firmware%20Upgrade%20Instruction%20for%20STM32%20base%20products/#H2.HardwareUpgradeMethodSupportList>>url:http://wiki.dragino.com/xwiki/bin/view/Main/Firmware%20Upgrade%20Instruction%20for%20STM32%20base%20products/#H2.HardwareUpgradeMethodSupportList]]
644 +
645 +**Notice, **CPN01 **and **CPN01 **share the same mother board. They use the same connection and method to update.**
646 +
647 +**5.2  Can I calibrate CPN01 to different soil types?**
648 +
649 +CPN01 is calibrated for saline-alkali soil and loamy soil. If users want to use it for other soil, they can calibrate the value in the IoT platform base on the value measured by saline-alkali soil and loamy soil. The formula can be found at [[this link>>url:https://www.dragino.com/downloads/downloads/LoRa_End_Node/LSE01/Calibrate_to_other_Soil_20220605.pdf]].
