Work with ROCK Pi S Ubuntu
What is ROCK Pi S Ubuntu
ROCK Pi S Ubuntu is an easy to use system. While working with ROCK Pi S Ubuntu, you will find it do well on playing music, Internet, Bluetooth and so on.
Access from the Host PC/Laptop
Option 1: USB access(adb)
By default, the ROCK Pi S Linux image enables adbd services, which is a debug bridge from Android now ported on Linux. With one USB A to C cable you can power and access the board, very handy.
After you have adb installed successfully, run the following command on console to login the shell of ROCK Pi S:
Check Using adb.
Option 2: Serial console
Check Serial Console
Option 3: SSH
SSH server is enabled on port 22 of ROCK Pi S default image.
Please use angryip to find your board IP address.
To access ROCK Pi S by SSH, try
ping rockpis.local ssh [email protected]
or if your router/network doesn’t support Local Domain, you need to check your network/router administrator page and look for the ROCK Pi S ip address.
ping ip-of-device ssh [email protected]
Note: You can also get the IP of ROCK Pi S from option 1 or option 2 if you can not access network administrator page.

Install and update necessary packages
Add Radxa APT, see Radxa APT.
$ sudo apt-get update $ sudo apt-get install -y rockchip-overlay $ sudo apt-get install -y linux-4.4-rockpis-latest rockpis-dtbo
There are two methods for network connection. One is Ethernet and the other is WIFI.
You can use a network cable (one end connected to the external network port or route) to connect your ROCK Pi S to the network. The ROCK Pi S will automatically configure the network for your surfing on the Internet.
To test the Ethernet, we need to follow the steps:
- Switch to super user mode by command
$ sudo su
- Check whether the Ethernet is normal by command, ifconfig, which would show us a network card, eth0, and the Ethernet IP address. Also, use tool, ping, to connect to a normal domain.
$ ifconfig $ ping www.baidu.com
- If failed to connect to a normal domain. , try
$ sudo dhclient eth0
When there is not a network cable for your ROCK Pi S the WIFI connection is another good choice. ROCK Pi S supports 2.4G WIFI wireless network.
To test the WIFI performance, we need to follow the steps:
- Switch to super user mode
$ sudo su
- Open the WIFI
$ nmcli r wifi on
- Scan WIFI
$ nmcli dev wifi
- Connect to WIFI network
$ nmcli dev wifi connect "wifi_name" password "wifi_password"
- Test WIFI perpormance by tool iperf.
Update necessary packages
$ sudo apt-get update $ sudp apt-get install -y rockchip-overlay $ sudo apt-get install -y linux-4.4-rockpis-latest # kernel version(>=126.96.36.199) $ sudo apt-get install -y rtl8723ds-firmware bluez
Check Bluetooth service
$ systemctl status bluetooth
Run Bluetooth service if the Bluetooth service is inactive.
$ systemctl start bluetooth
Check Bluetooth device
$ hciconfig hci0: Type: Primary Bus: UART BD Address: 22:22:AA:25:49:1E ACL MTU: 1021:8 SCO MTU: 255:12 UP RUNNING RX bytes:4424 acl:0 sco:0 events:81 errors:0 TX bytes:3820 acl:0 sco:0 commands:52 errors:0
Example: Connect to Bluetooth Speaker.
Change to root mode.
$ sudo su
Install pulseaudio packages
# apt-get install -y pulseaudio-module-bluetooth pulseaudio
# pulseaudio --start
Connect using bluetoothctl
# bluetoothctl [bluetooth]# default-agent [bluetooth]# power on [bluetooth]# scan on [bluetooth]# trust 77:EC:79:4F:6B:AC [bluetooth]# pair 77:EC:79:4F:6B:AC [bluetooth]# connect 77:EC:79:4F:6B:AC
