Installation

Install OS to Raspberry Pi Zero

The image used 2018-11-13-raspbian-stretch-lite.img

Steps from Mac OS, but should be similar for any other OS

Install OS to SD card (I used Etcher app)
When the image is flashed successfully, modify Raspbian configuration files:

diskutil list
sudo diskutil mountDisk /dev/disk1

wifi_ssid=your_ssid
wifi_password=your_password

echo "
dtoverlay=dwc2
enable_uart=1' >> /Volumes/boot/config.txt

touch /Volumes/boot/ssh

echo 'ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=US

network={
    ssid=\"$wifi_ssid\"
    psk=\"$wifi_password\"
    key_mgmt=WPA-PSK
}" > /Volumes/boot/wpa_supplicant.conf

Insert SD to Raspberry Pi Zero
ssh pi@raspberry-ip where username is pi and password is raspberry
Run the scripts on Raspberry

cd ~
sudo apt update && sudo apt install git -y
git clone https://github.com/laimison/eranet-remote.git
cd eranet-remote
git config user.name laimison
./install.sh

Use keyboard, power button and setup video stream, please run:

cd ~/eranet-remote && ./control.sh

Troubleshooting

Check whether you are receiving video stream

On Raspberry

sudo tcpdump -i wlan0 port 5004

laimison / eranet-remote
