Raspberry Pi Series (2)-Install the system and connect

install the system

1. Download system installation tool: system installation tool
2. Download system: system
3. Format the memory card
4. install the system

Connect Raspberry Pi to view configuration information

1. Create a new file in the boot root directory wpa_supplicant.conf, the content of the file is as follows

country=CN
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
 
network={
ssid="TP-LINK_3730"
psk="fujinjiayuan202@"
key_mgmt=WPA-PSK
priority=2
#scan_ssid=1
}

network={
ssid="HONOR 20 Lite"
psk="12345678"
key_mgmt=WPA-PSK
priority=1
}

#ssid:网络的ssid
#psk:密码
#priority:连接优先级，数字越大优先级越高（不可以是负数）
#scan_ssid:连接隐藏WiFi时需要指定该值为1

• If your WiFi has no password

network={
ssid="你的无线网络名称（ssid）"
key_mgmt=NONE
}

• If your WiFi uses WEP encryption

network={
ssid="你的无线网络名称（ssid）"
key_mgmt=NONE
wep_key0="你的wifi密码"
}

• If your WiFi uses WPA/WPA2 encryption

network={
ssid="你的无线网络名称（ssid）"
key_mgmt=WPA-PSK
psk="你的wifi密码"
}

2. create a new filessh
3. xshell remote connection
   Enter the router to find the ip address of this raspberry pie, connect with the xshell tool, the default user name and password are as follows

There is another way to find the ip: use the LAN ip scanner to scan the newly added ip even the ip address of the Raspberry Pi
