Connect to rpi-config-ap using password password.

Logger server on self-hosted access point is at http://192.168.88.1

Access point will be available around 60 seconds after the Pi is connected to power.

Configure Raspberry Pi From Base Image.

Get Base Image

• Go to https://www.raspberrypi.org/software/operating-systems/ and download the latest Rasperry Pi OS Lite image.
• Flash the image to a microSD card.
• Don't remove the microSD card!

Configure Pi USB Ethernet Gadget

• With the microSD card still in the machine we flashed from.
• Navigate to the root level of the microSD card.
• Edit config.txt and add dtoverlay=dwc2 as the last line.
• Edit cmdline.txt after the word rootwait add a space and then modules-load=dwc2,g_ether
• Create a new empty file named ssh with no extention.
• Now when the Pi is connected to a machine via USB we can SSH into it at raspberrypi.local
• NOTE Windows users may need to add Bonjour support so it knows what to do with .local names. The easiest way to do this is to install iTunes. More information here https://learn.adafruit.com/bonjour-zeroconf-networking-for-windows-and-linux/.

Give the Pi Internet Access

• Connect the Pi to the host machine.
• In the system settings of the host machine, bridge a network adapter with internet access and the usb ethernet adapter that is presented from the Pi.
• Now SSH into the Pi and test the network connectivity by trying ping 8.8.8.8 (Google's DNS).
• NOTE default SSH credentials are user:pi and password:raspberry

Install Dependencies

• Update package list with sudo apt-get update.
• Install hostapd with sudo apt-get install hostapd.
• Install dhcpcd with sudo apt-get install dhcpcd.
• Install git with sudo apt-get install git.
• Enable the NodeSource repository by running curl -sL https://deb.nodesource.com/setup_10.x | sudo bash -.
• Update package list with sudo apt-get update.
• Install Node.js and npm with sudo apt-get install nodejs.

Clone Repository and Install Node Packages

• SSH into the Pi and navigate into /home/pi if you're not there already.
• Clone the yada-logger repository with git clone https://github.com/Yet-Another-Data-Aggregator/yada-logger.git.
• CD into the yada-logger folder.
• Get the needed packages with npm install.

Install Python Packages

• Install pip3 with sudo apt-get install python3-pip
• Navigate to ```/home/pi/yada-logger/src'''
• Install firebase_admin with sudo pip3 install firebase_admin
• Uninstall grpc library with sudo pip3 uninstall grpcio
• Fix grpc library by rebuilding with sudo pip3 install --upgrade --no-binary :all: grpcio. This command builds grpcio from source and may take a long time to build on a pi zero.

Configure Startup Scripts

• Run sudo crontab -e using nano.
• Add the line @reboot cd /home/pi/yada-logger && sudo /usr/local/bin/node server.js &
• Add the line @reboot cd /home/pi/yada-logger/src && sudo /usr/bin/python3 main.py &
