1 Access Point Setup Guide
1.1 Compatible development boards and systems
At the time of writing this guide, the following development boards and systems were tested. Although this is not a complete list, theoretically they should work as long as the wireless modules are of the same type：
1.1.1 RK3399
- NanoPi M4 (Wireless module：AP6356S)
- NanoPi M4B (Wireless module：AP6256)
- NanoPC T4 (Wireless module：AP6356S)
1.1.2 S5P4418/S5P6818
- NanoPC T3 (Wireless module：AP6212)
- NanoPC T2 (Wireless module：AP6212)
1.1.3 Allwinner H3/H5
- NanoPi-M1-Plus (Wireless module：AP6212)
1.1.4 OS
The following distributions are supported ：
- FriendlyCore Focal (20.04)
- FriendlyCore Bionic (18.04)
- FriendlyCore Xenial (16.04)
- FriendlyDesktop (18.04)
1.2 Installing the necessary tools
Execute the following command to install the necessary packages：
sudo apt-get update sudo apt-get install -y git bash util-linux procps hostapd iproute2 iw wireless-tools haveged dnsmasq iptables
If you are using the lite version of the firmware (e.g. FriendlyCore-Lite), it is also recommended to install network-manager, otherwise you will need to manually turn on the wireless interface, as by default it will be in down state.：
sudo apt-get -y install network-manager
Install the create_ap tool：
git clone https://github.com/friendlyarm/create_ap.git cd create_ap make install
Make sure the wlan interface is in up state：
sudo ifconfig wlan0 up
1.3 Set up access point
Note: In the following description, the access point name is the model name of the development board obtained from the /etc/friendlyelec-release file, and 12345678 is the password of the access point.
1.3.1 Bridging Mode
The device connected to this AP will be in the same network segment as eth0 (the device is assigned an IP address by the router to which eth0 is connected, if the router has dhcp enabled):
. /etc/friendlyelec-release sudo create_ap --country CN --ieee80211n --ht_capab "[DSSS_CK-40][HT20+]" \ --driver nl80211 -w 2 -m bridge wlan0 eth0 ${BOARD_NAME} 12345678 --no-virt \ --no-haveged --mkconfig /etc/create_ap.conf sudo create_ap --config /etc/create_ap.conf
1.3.2 Routing Mode
The device connected to this AP is on a different subnet than eth0 (the device is assigned an ip address by the dhcp server running on the development board)：
. /etc/friendlyelec-release sudo create_ap --country CN --ieee80211n --ht_capab "[DSSS_CK-40][HT20+]" \ --driver nl80211 -w 2 wlan0 eth0 ${BOARD_NAME} 12345678 --no-virt --no-haveged \ --mkconfig /etc/create_ap.conf sudo create_ap --config /etc/create_ap.conf
1.3.3 Routing Mode (Network Isolation)
Much the same as Routing Mode, but the difference is that the devices connected to this AP are not accessible to each other:
. /etc/friendlyelec-release sudo create_ap --country CN --ieee80211n --ht_capab "[DSSS_CK-40][HT20+]" \ --driver nl80211 -w 2 --isolate-clients wlan0 eth0 ${BOARD_NAME} 12345678 \ --no-virt --no-haveged --mkconfig /etc/create_ap.conf sudo create_ap --config /etc/create_ap.conf
1.4 Set the wireless access point to be enabled automatically on boot
systemctl enable create_ap sudo reboot
