https://www.ev3dev.org/docs/tutorials/setting-up-wifi-using-the-command-line/

To connect:

> ssh [email protected]
> ssh [email protected] (latest)

password: maker

Before doing use apt-get:

> sudo apt-get update

To update the brickpi3 firmware:

> sudo update-brickpi3-fw

If you use asdf to install erlang and elixir, first do:

> sudo apt-get install build-essentials
> sudo apt-get install autoconf
> sudo apt-get install libncurses5-dev
> sudo apt-get install libssl-dev

To install Erlang and Elixir via asdf:

Install asdf -- See https://asdf-vm.com/#/core-manage-asdf-vm

> echo -e '\n. $HOME/.asdf/asdf.sh' >> ~/.bashrc
> echo -e '\n. $HOME/.asdf/completions/asdf.bash' >>  ~/.bashrc # optional
> source ~/.bashrc

Then:

> asdf plugin-add erlang
> asdf plugin-add elixir
> asdf install erlang 21.2.2 # Any OTP 21 version should work
> asdf install elixir 1.8.1-otp-21
> asdf global erlang 21.2.2
> asdf global elixir 1.8.1-otp-21

To get the source code for Andy on the Raspberry Pi:

> git clone https://github.com/jfcloutier/andy.git
> cd andy
> mix deps.get
> mix compile

To update the source code:

> git checkout master
> git pull

To reset the robot (erase its accumulated experience)

> rm memory.dets

To launch on the robot:

> ANDY_SYSTEM=brickpi ANDY_PLATFORM=rover iex -S mix

To stop the robot and retain newly acquired experience:

> Andy.shutdown

To test on PC with mock rover:

> iex -S mix
