Assemble base station
Base station might include different hardware components. Please check recommended bill of materials. This is very basic setup, but it is guaranteed to be working.
Installation
- Install r2cloud
-
From the image. This is the easiest way to install r2cloud on Raspberry PI. It will require brand new SD card:
- Download the latest official image
- Insert SD card into the card reader and flash it. You could use Etcher to do this
- Insert SD card into the card reader and create file
r2cloud.txtin the root directory. This file should contain any random string. This string is a login token. This token will be used during initial setup.
-
Or from repository binaries:
- Login via SSH and create
r2cloud.txtfile in /boot directory. This file should contain any random string. This string is a login token. This token will be used during initial setup. - Execute the following commands:
- Login via SSH and create
sudo apt-get install dirmngr lsb-release
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A5A70917
sudo bash -c "echo 'deb http://s3.amazonaws.com/r2cloud $(lsb_release --codename --short) main' > /etc/apt/sources.list.d/r2cloud.list"
sudo apt-get update
sudo apt-get install r2cloud
- Open https://raspberrypi.local address.
- Accept self-signed certificate. This is unique certificate that was generated during installation. Once setup is complete, you could enable proper SSL using Letsencrypt.
Design guidelines
- Autonomous:
- Ability to operate without internet connection
- synchronize state once connection restored
- automatically calibrate average absolute error
- configure base station location based on coordinates from GPS receiver
- new decoders could be added after auto-update
- Integration with external systems:
- share as much as possible data with external systems
- re-use libraries
- Single stack
- focus on single hardware and software stack
- optimize it
- Stability
- housekeeping logs and data based on available hard disk
- auto-update
- backward compatibility
- Security
- safe to expose administration UI to the internet
Details could be found in official documentation.
