Before start

The Radxa Rock provides various ways to connect, wired and wireless. The full version has wifi and BT on board, and lite version has wifi only. Both module are connect to the cpu via the USB interface.

Using wireless under Android

The wifi and BT (if has) works out of the box, check out in the Setting to configure it.

Using wireless under Linux

Wifi

The model number of the module on RR and RR lite is RTL8723AU on RR full version and RTL8188ETV on lite version. You can see the id of the module with the following command on RR:

   sudo apt-get install usbutils
   lsusb

For RR full version the output is

   root@radxa:~# lsusb
   Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
   Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
   Bus 002 Device 002: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB
   Bus 002 Device 003: ID 0bda:0724 Realtek Semiconductor Corp.

on lite version, the output is:

   Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub                  
   Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub                  
   Bus 002 Device 002: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB         
   Bus 002 Device 003: ID 0bda:0179 Realtek Semiconductor Corp.    

The 0bda:0724 is the id of rtl8723 modlue, the 0bda:0179 is the id of rtl8188etv module.

Desktop

   Go to Start menu -> Perference -> Network Connections -> wifi, choose the wifi network you want to join and click edit -> wifi security, input the wifi password and save. Then click the right corner to join your wifi network.

Manually connect with Network Manager

You can use nmcli (Network Manager Command Line Interface) to configure your network interfaces.

List wireless networks

# nmcli dev wifi list

# nmcli dev wifi connect MY-ACCESS-POINT password MY-PASSWORD

Manually config to connect wireless router

To use RR(lite) to connect to your wireless router, you need to do the following:

   sudo apt-get install wireless-tools
   sudo apt-get install wpasupplicant
   sudo ifconfig wlan0 up

If you are unable to bringup wlan0, mean drivers are not installed. Follow this step to add driver. Assumes you have net connection thru ethernet, else download and move

   sudo mkdir -p /lib/modules && cd /lib/modules
   sudo wget http://dl.radxa.com/rock/images/ubuntu/partitions/modules_3.0.36+_14-04-12.tar.gz
   sudo tar zxvf modules_3.0.36+_14-04-12.tar.gz
   sudo rm modules_3.0.36+_14-04-12.tar.gz
   sudo modprobe 8723au

now you should see wlan0 by ifconfig

Now you can view is the wifi module works by scanning the AP nearby

   iwlist wlan0 scan

For the new wifi driver, iwlist will report wlan0 Interface doesn't support scanning. you need to use the new tool iw instead

   iw dev wlan0 scan

edit /etc/wpa_supplicant.conf

   ctrl_interface=/var/run/wpa_supplicant
   network={
   	ssid="your ssid name"
   	psk="your wireless password"
   }

and then run

   wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf 

to connect to the wireless router.

run the following to get an IP from the router.

   dhclient wlan0

If you want to set the RR to connect to the wireless router automatically every time it boot up. Add the following to the /etc/network/interfaces

   auto wlan0
   iface wlan0 inet dhcp
   wpa-conf /etc/wpa_supplicant.conf

AP mode(RR as the wireless router)

Easily Make Your Own HostAP(8723au)

first ,ensure your network function well on board

to get the hostap package(8723au) 8723au_hostapd_linux.tar.gz.

tar zxf  rock_pro_8723au_hostapd_linux.tar.gz
cd rock_pro_8723au_hostapd_linux
make install
reboot
Easily Make Your Own HostAP(8188eu)

In the same way,to get the hostap package(8188eu) 8188eu_hostapd_linux.tar.gz.

tar zxf 8188eu_hostapd_linux.tar.gz
cd 8188eu_hostapd_linux
make install
reboot

You can also configure wifi as AP mode manually, please refer AP mode manually.

BT

to get the driver:

  git clone https://github.com/lwfinger/rtl8723au_bt

To compile the driver, you need to have compiled your own Kernel like described in

 http://wiki.radxa.com/Rock/Booting_Linux

Then on your Linux host computer you will find a directory "/lib/modules/3.0.36+/" containing a "kernel" directory and two symbolic links called "build" and "source" to your Rockchip kernel source directory (originally called "rockchip-3.0") wherever you downloaded it to. This is the prerequisite for compiling rockchip modules.

Then change into the BT driver directory rtl8723au_bt and edit the textfile called "Makefile". My "Makefile" now looks like this, I marked the changes bold:

 FW_DIR	:= /lib/firmware/rtk_bt
 MDL_DIR	:= /lib/modules/3.0.36+
 DRV_DIR	:= $(MDL_DIR)/kernel/drivers/bluetooth
     
 ifneq ($(KERNELRELEASE),)
     
        obj-m := rtk_btusb.o
     
 else
    PWD := $(shell pwd)
    KVER := "3.0.36+"
    KDIR := /lib/modules/3.0.36+/build
      
 all:
    $(MAKE) -C $(KDIR) M=$(PWD) modules
   
     
 clean:
     rm -rf *.o *.mod.c *.mod.o *.ko *.symvers *.order *.a
 endif
     
 install:
      mkdir -p $(FW_DIR)
      cp -f rlt8723a_chip_b_cut_bt40_fw_asic_rom_patch-svn8511-0x0020342E-20121105-LINUX_USB.bin $(FW_DIR)/rtk8723a.bin
      cp -f rtk_btusb.ko $(DRV_DIR)/rtk_btusb.ko
      #depmod -a $(MDL_DIR)'
      #echo "install rtk_btusb success!
      
 uninstall:
      rm -f $(DRV_DIR)/rtk_btusb.ko
      depmod -a $(MDL_DIR)
      rm -f $(FW_DIR)/rtk8723a.bin
      echo "uninstall rtk_btusb success!"


Then do

 export ARCH=arm
 export CROSS_COMPILE=arm-linux-gnueabihf-
 make
 sudo make install

After that copy the following files from the host system into the same folder on Radxa Rock:

 /lib/firmware/rtk_bt/rtk8723a.bin
 /lib/modules/3.0.36+/kernel/drivers/bluetooth/rtk_btusb.ko

Last on Radxa Rock system change into the folder

 /lib/modules/3.0.36+/kernel/drivers/bluetooth 

and enter the command

 sudo insmod rtk_btusb.ko

Now "hcitool dev" recognizes the adapter (hci0) and "hcitool scan" finds remote BT devices. But I could not get any device to pair. Any ideas appreciated.
