106 = 2.  Use NLMS01 to communicate with IoT Server =
107
108 == 2.1  How it works ==
109
110 The NLMS01 is equipped with a NB-IoT module, the pre-loaded firmware in NLMS01 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 NLMS01.
111
112 The diagram below shows the working flow in default firmware of NLMS01:

116 == 2.2 ​ Configure the NLMS01 ==
117
118 === 2.2.1 Test Requirement ===
119
120 To use NLMS01 in your city, make sure meet below requirements:
121
122 * Your local operator has already distributed a NB-IoT Network there.
123 * The local NB-IoT network used the band that NLMS01 supports.
124 * Your operator is able to distribute the data received in their NB-IoT network to your IoT server.
125
126 Below figure shows our testing structure. Here we have NB-IoT network coverage by China Mobile, the band they use is B8.  The NLMS01 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

350
351 === 2.4.9  ​+5V Output ===
352
353 NLMS01 will enable +5V output before all sampling and disable the +5v after all sampling. 
354
355 The 5V output time can be controlled by AT Command.
356
357 **AT+5VT=1000**
358
359 Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.** **
360

472 === 2.12.2  Power consumption Analyze ===
473
474 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.
475
476 Instruction to use as below:
477
478 **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/]]
479
480 **Step 2: ** Open it and choose
481
482 * Product Model
483 * Uplink Interval
484 * Working Mode
485
486 And the Life expectation in difference case will be shown on the right.

490 === 2.12.3  ​Battery Note ===
491
492 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.
493
494 === 2.12.4  Replace the battery ===
495
496 The default battery pack of NLMS01 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).
