Set up Raspberry Pi without human I/O devices
I was able to set up Raspberry Pi only with MacBook and Mobile WiFi. It was lucky that I have Wireless LAN Router that I used to use.
These are all devices.
- Raspberry Pi 3 Model B+
- MacBook Air
- micro SD and SD connector
- Mobile WiFi
- Wireless LAN (no WAN connection!)
Step1. Write Raspbian Image on micro SD
Fortunetely I have MacBook and Mobile Wifi, it was easy to get raspbian OS image via internet. I got the image from official web site.After download, I inserted an SD into my MacBook and checked its disk number.
diskutil list
The disk number that I just inserted will be shown on console.If the SD has been already used as Raspberry Pi image disk, formatting will be required.
diskutil eraseDisk diskX
Then I got started to write OS image with the disk number.
diskutil unmountDisk /dev/diskX
sudo dd if=***.img of=/dev/rdiskX bs=1m
I created a blank file on boot directory in order to enable SSH on raspberry pi.
sudo dd if=***.img of=/dev/rdiskX bs=1m
mount
echo '' >> /Volumes/boot/ssh
echo '' >> /Volumes/boot/ssh
Step2 Enter Raspberry Pi console
I connected Raspberry Pi and Wireless LAN with physical cable and connected MacBook and Wireless LAN with WiFi. The arp command is available for obtaining a IP address of Raspberry Pi.
arp -a
Then I established SSH connection with the IP address.
ssh pi@xxx.xxx.xxx.xxx
The default password is raspberry.
Step3 Set up WiFi connection
First I made sure that the Raspberry Pi is successfully receiving wireless network.
sudo iwlist wlan0 scan | grep ESSID
Then I was set SSID and WPA password on wpa_supplicant.conf,
sudo vi /etc/wpa_supplicant/wpa_supplicant.conf
and added the following descriptions.
country=JP
network={
ssid=“”
psk=“”
}
The raspberry pi get started to catch WiFi, after reboot.
network={
ssid=“”
psk=“”
}
sudo reboot
IP address will be changed because network I/F is different from physical LAN.
ssh pi@yyy.yyy.yyy.yyy
Physical network might not be necessary if WiFi conficuration on wpa_supplicant.conf has been set up, when I constructed raspbian OS on the micro SD card.
