2.3	90	== 2.1 How it works ==
2.2	91
3.2	92
2.2	93	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.
	94
	95	The diagram below shows the working flow in default firmware of NDS01:

4.2	100	== 2.2 Configure the NDS01 ==
2.2	101
2.3	102	=== 2.2.1 Test Requirement ===
2.2	103
	104
	105	To use NDS01 in your city, make sure meet below requirements:
	106
	107	* Your local operator has already distributed a NB-IoT Network there.
	108	* The local NB-IoT network used the band that NDS01 supports.
	109	* Your operator is able to distribute the data received in their NB-IoT network to your IoT server.
	110
17.19	111	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.

2.2	118
7.2	119
2.2	120	Insert the NB-IoT Card get from your provider.
	121
	122	User need to take out the NB-IoT module and insert the SIM card like below:

	126
2.4	127	=== 2.2.3 Configure NDS01 ===
2.2	128
7.2	129
2.2	130	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.
