3 Hardware Setup

The NanoPi Duo2 can be mounted on the NanoPi Duo2 IoT-Box carrier board. You can refer to the following setup to assemble them:
NanoPi Duo2 IoT-Box_NanoPi_Duo2

You can connect your NanoPi Duo2 IoT-Box board to a network and external modules such as USB devices
NanoPi Duo2 IoT-Box

When you use the onboard quad-band GSM/GPRS module you should use an appropriate antenna and this antenna's band is different from an WiFi antenna's band. You can refer to the following setup:
NanoPi Duo2 IoT-Box Assemble an antenna

4 Applications

4.1 Work with GSM/GPRS Module

To test SIM800C you need to insert a SIM card and install a GSM/GPRS antenna.
By default the FriendlyCore system FriendlyElec provides has a Python demo for testing SIM800C. Run the following commands to test it: 

$ cd /root/Python/GSM-GPRS/sim800-test
$ apt-get install python-pip
$ pip install --upgrade pip
$ pip install pyserial
$ ./sim800c-test.py -h              # Check help information
./sim800c-test.py -p <phone_number> -o <operator, cmcc> -w <website>
$ ./sim800c-test.py -p 136xxxxxxxx  -o cmcc -w www.baidu.com  # Visit baidu.com
Option Comment
-p specifies a telephone number for sim card.
-o specifies a telecom operator. For example "cmcc" stands for China Mobile Communication Corporation.
-w specifies a website to visit

By default this demo will load 1K bytes' data from the specified website and it takes a while. If it is successful you will see the following information:

4.2 Work with USB Host

You can connect a USB device e.g. Matrix - LCD2USB to the NanoPi Duo2 IoT-Box board as follows:
连接Matrix - LCD2USB

4.3 Work with Audio Input & Output

1. Run the following command to record voices: 

arecord -D hw:0,0 -f cd test.wav

Here is what you expect to observe:
Voice Recording
2. Run the following command to play audio e.g. the /root/Music/test.wav file 

 aplay /root/Music/test.wav

Here is what you expect to observe:
Audio Play

You can use the alsamixer utility to adjust the volume.
