Setup

The central device (server) has been tested with a Raspberry Pi Zero W.

Connectivity Issues

For whatever reason, RPIs dislike setting themselves up properly. Before continuing, make sure you can ping google.com sucessfully. If something seems off, try the following solutions:

Improper Hostname

Make sure your hostname has been properly changed, especially if this is a newly installed PI. Type in sudo nano /etc/hosts and make sure that the line starting with 127.0.1.1 has the proper hostname and that sudo nano /etc/hostname also shows the proper hostname (source).

DNS Resolution

Sometimes the default DNS servers are just bad. Run the command echo "nameserver 8.8.8.8" | sudo tee -a /etc/resolv.conf.head to add google.com to the list of nameservers to use (source).

To install the HFS library in /usr/local/src/, run the following command:

wget -O hfs.zip "https://github.com/LESA-RPI/hfs.main/archive/refs/heads/main.zip" && sudo unzip -o -j hfs.zip 'hfs.*/sensor/server/*' -d /usr/local/src/hfs/ && rm hfs.zip

Then to build the server dependencies and begin server setup, run:

sudo sh /usr/local/src/hfs/install.sh

To start the server, simply reboot the PI and both the webpage and bluetooth capabilities will automatically launch.

Finally, one might want to simply update the code on the server. To do so, run:

wget -O hfs.zip "https://github.com/LESA-RPI/hfs.main/archive/refs/heads/server-ui.zip" && sudo unzip -o -j hfs.zip 'hfs.*/sensor/server/*' -d /usr/local/src/hfs/ && rm hfs.zip && (cd /usr/local/src/hfs && sudo mkdir -p public && sudo mv -v *.html public/ && sudo mv -v *.css public/ && sudo touch public/public.log && sudo npm install)

Raspberry Pi System has been upgraded to the Raspberry Pi 4, and the username and password are the same.
