If you want to use the radxa rock as a WIFI-AP under android . you can enable the item in settings(More->Portable hotspot->Portable Wi-Fi hotspot).

But the setting will be cancelled after reboot. we provider image resolves the problem,you can download here.140224_android_softAp.tgz.

AP mode(RR acts as wireless router)

Enable your hostAP easier


Prepare works

1.1 Compile hostapd 

wget http://dl.radxa.com/rock/source/RTL8723A_WiFi_linux_v4.1.7_8023_BTCOEX20130528_ver3.3_beta.rar
sudo apt-get install unrar
unrar x RTL8723A_WiFi_linux_v4.1.7_8023_BTCOEX20130528_ver3.3_beta.rar
sudo apt-get install build-essential
cd RTL8723A_WiFi_linux_v4.1.7_8023_BTCOEX20130528_ver3.3_beta/
cd wpa_supplicant_hostapd/
tar xzf wpa_supplicant_hostapd-0.8_rtw_r7048.20130424.tar.gz
cd wpa_supplicant_hostapd-0.8_rtw_r7048.20130424/
make
sudo make install
sudo mkdir -p /etc/hostapd

1.2 Install toolchain.

1.3 Download the kernel from the address: root@radxa:/tmp# git clone -b radxa-stable-3.0 https://github.com/radxa/linux-rockchip.git

or download here

Compile the driver

Attention please： first,ensure your kernel has been compiled
unrar x RTL8723A_WiFi_linux_v4.1.7_8023_BTCOEX20130528_ver3.3_beta.rar
cd RTL8723A_WiFi_linux_v4.1.7_8023_BTCOEX20130528_ver3.3_beta
cd driver
tar zxvf rtl8723A_WiFi_linux_v4.1.7_8023.20130628_BTCOEX20130528_ver3.3_beta.tar.gz
cd rtl8723A_WiFi_linux_v4.1.7_8023.20130628_BTCOEX20130528_ver3.3_beta

Build wifi driver

root@radxa:/tmp/driver/rtl8723A_Wi...3.3_beta# make

root@radxa:~# rm /lib/modules/3.0.36+/kernel/drivers/net/wireless/rtl8723au_lwfinger/8723au.ko

root@radxa:~# cp wlan.ko /lib/modules/3.0.36+/kernel/drivers/net/wireless/rtl8723au_lwfinger

root@radxa:~# reboot

Configure dhcp server,wifi(user,password),autorun the softAP
3.1 Configure static IP
root@radxa:/etc#vim /etc/network/interfaces
auto wlan0
iface wlan0 inet static
address 192.168.2.1
netmask 255.255.255.0
3.2 Configure the dhcp server

root@radxa:/etc# apt-get install dnsmasq

root@radxa:/etc# vim dnsmasq.conf 

interface=wlan0 
bind-interfaces 
except-interface=lo  
dhcp-range=192.168.2.150,192.168.2.254,12h  #configure the range of available ip
dhcp-option=3,192.168.2.1  #configure the server
3.3 Make your network faster

root@radxa:/etc# apt-get install haveged

3.4 Configure the wifi(user,password):

root@radxa:/etc# cp /tmp/RTL8723A_WiFi_/wpa_supplicant_hostapd/rtl_hostapd_2G.conf /etc/hostapd/hostapd.conf

root@radxa:/etc# vim /etc/hostapd/hostapd.conf 

interface=wlan0
ctrl_interface=/var/run/hostapd
ssid="user-name"
channel=6
wpa=2
wpa_passphrase="password"
#bridge=br0
3.5 Autorun your softAP:

root@radxa:/etc# vim wifs.sh 

#!/bin/sh
#start the AP service
#Start hostapd, and it will automatically be bringed up 
sudo hostapd -B /etc/hostapd/hostapd.conf
#Set ip on wlan0 
sudo /sbin/ip addr add 192.168.2.1/24 dev wlan0
#Start dnsmasq 
sudo /usr/sbin/service dnsmasq start
#Start ip_forward 
sudo echo 1 > /proc/sys/net/ipv4/ip_forward
#add iptables rule for NAT 
sudo /sbin/iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
#start haveged
sudo /etc/init.d/haveged start

root@radxa# vim /etc/rc.local 

/etc/wifs.sh
/lib/init/vars.sh
/lib/lsb/init-functions

root@radxa# reboot
