Initial setup
I’ve connected RPi to TV to perform initial configuration as it doesn’t have ssh service enabled by default anymore.
OS installation
I’ve selected Raspbian Stretch With Desktop as my OS for RPi. It seems the most popular OS for RPi and I have a previous experience with Ubuntu and they have a common parent Debian. It took significant amount of time to complete the install. Here is my current OS version.
pi@raspberrypi:~$ uname -a Linux raspberrypi 4.19.34-v7+ #1211 SMP Mon Apr 8 22:56:37 BST 2019 armv7l GNU/Linux
Network and Security setup
Then I’ve setup wifi.
Enabling of SSH is well documented https://www.raspberrypi.org/documentation/remote-access/ssh/
Setup a Static IP Address
As I prefer to work with RPi over SSH I’d like to have a static IP for it. I’ve followed instructions from Stackoverflow Static IP Address to set it up:
I’ve edited /etc/dhcpcd.conf
By setting the following:
interface wlan0 static ip_address=192.168.1.63/24 static routers=192.168.1.1 static domain_name_servers=192.168.1.1 8.8.8.8 1.1.1.1
And then I’ve restarted network service:
sudo service networking restart
Setup ssh access with authorized key
I’ve generated a new keys with PuttyGen and added the public key to
.ssh/authorized_keys file. At the same time I’ve specified my private key file in my ssh client as Authentication parameter.
Disable password access
As popularity of RPi growths it can become the new security risk for you, So after setting up access with the key I’ve disabled access using password as described in https://raspberrypi.stackexchange.com/questions/3435/how-can-i-deactivate-the-login-password-on-my-raspberry-pi .
Setup Bluetooth
I need to setup BLE to communicate with my sensors and audio output.
First setp is to Add the pi user to the audio and the bluetooth groups:
sudo adduser pi bluetooth
then’ve check if BLE is enabled:
pi@raspberrypi:~$ ps -ef | grep bluealsa root 693 1 0 21:21 ? 00:00:00 /usr/bin/bluealsa pi 923 807 0 21:44 pts/0 00:00:00 grep bluealsa
Then I’ve used BLE control tool bluetoothctl to connect setup connection and trust between RPi and my devices as per https://raspberrypi.stackexchange.com/questions/90267/how-to-stream-sound-to-a-bluetooth-device-from-a-raspberry-pi-zero instruction.
