Setup from scratch for Development

these steps have already been completed for the two pis we have

Raspberry Pi SD card Setup for SSH over USB

1. open sd card root on another system

2. append the following to config.txt:

   dtoverlay=dwc2

3. put the folling in cmdline.txt after rootwait:

   modules-load=dwc2,g_ether

4. create an empty file named 'ssh' in the root directory.

Setup bluetooh connection

from https://hacks.mozilla.org/2017/02/headless-raspberry-pi-configuration-over-bluetooth/

1. run the following commands (on the pi (somehow))

mv setup/btserial.sh /home/pi/
sudo chmod +755 /home/pi/btserial.sh

2. add sudo /home/pi/btserial.sh & to /etc/rc.local

3. reboot pi

Installing rmate for remote editing via sublime -- see https://github.com/randy3k/RemoteSubl

1. Run the following commands from this directory after copying this repo to a raspberry pi

mv setup/rmate /usr/local/bin/
sudo chmod +x /usr/local/bin/rmate

2. Install sublime text on development machine

3. Install the RemoteSubl package

4. Run rmate FILE on the raspberry pi to edit the file in sublime text on the dev machine. Will automatically save to the pi.

Connecting to the Raspberry Pi remotely (only confirmed working on MacOs/Unix -- might work on WSL)

via ssh

• (with rmate enabled) ssh -R 52698:localhost:52698 pi@<HOSTNAME>.local
• (without rmate port) ssh pi@<HOSTNAME>.local

<HOSTNAME> is "raspberrypi0" for the reciever raspberry pi and "raspberrypi1" for the sender.

via Bluetooth (currently not working)

1. Boot the pi
2. turn on bluetooth
3. ls /dev/cu.* to look for the pi
4. screen /dev/cu.raspberrypi-SerialPort 115200
