- Installation
Download and install raspbian (debian for raspberry) lite package (same for PI3 and PIzero)
Raspberry Pi OS (32-bit) Lite (buster : 433M)
wget https://downloads.raspberrypi.org/raspbian_lite_latest
mv raspbian_lite_latest raspbian_lite_latest.zip ./balenaEtcher-1.5.79-x64.AppImage
- Initial configuration:
PI3 and PIZero can be configured headless, without a keyboard and a display.
You just need to configure the board to connect to a wifi hotspot when power on.
- Plug the memory SD card with the fresh raspbian installed.
Create file (sudo touch)
boot/ssh
Create the file with following content (sudo vi)
boot/wpa_supplicant.conf " ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_config=1 country=FR network={ ssid="Androidxp" psk="pprzpprz" } network={ ssid="pprz_router" key_mgmt=NONE } "
- Plug the SD memory card in the raspberry Pi and power on.
- Connect your computer to the same wifi hotspot
- Look for the Raspberry IP on the network
nmap -sn 192.168.1.0/24
- Connect to the identified IP
