mPCIe WiFi RedPine RS9113 card
The RS9113 USB Half Mini Card is based on Redpine Signals’ RS9113 ultra-low-power Convergence SoC. It offers dual-band 1x1 802.11n, dual-mode Bluetooth 4.0, and ZigBee 802.15.4 in a single device over USB in a Mini PCIe card form factor.
The RB350 has one Mini PCI Express card connector where you can mount the RedPine RS9113 card. The RS9113 card is a Half Mini Card, but the connector is for a Full Mini Card, so you need an adapter. There is also a possibility to mount a connector for a Half Mini Card during production.
Driver installation
Drivers installation requires a kernel build. For our customers we provide rs9113.sh script for that.
$ chmod +x rs9113.sh ./rs9113.sh After successful installation of the driver interfaces wlan0 and zigbe0 should be created. This can be seen using 'ifconfig' command.
By default RS9113 card is configured in Wi-Fi station and ZiGB station mode (mode dev_oper_mode=17). You can change mode by editing the file:
$ nano /etc/modprobe.d/rsi_91x.conf and change dev_oper_mode to required. For example:
- Wi-Fi station mode dev_oper_mode=1,
- Wi-Fi and Bluetooth EDR mode dev_oper_mode=5,
- ZigBee station mode dev_oper_mode=16.
For more details, see Chapter 3.3 of the Technical Reference Manual.

Scanning for WiFi Networks
To scan for WiFi networks, use the following command:
$ sudo iwlist wlan0 scan Configuring Wifi
The quickest way to enable wireless networking is by using the command-line raspi-config tool:
$ sudo raspi-config Select the Network Options item from the menu, then choose Wi-Fi. Enter the SSID of the network and the passphrase. For more information, see Raspberry Pi setting WiFi.
To check the WiFi connection:
$ ifconfig wlan0
wlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.1.163 netmask 255.255.255.0 broadcast 192.168.1.255

By default, the internal antenna is configured.
To select the external antenna:
$ ifconfig wlan0 down iw phy phy0 set antenna 1 0
$ ifconfig wlan0 up To select the internal antenna:
$ ifconfig wlan0 down iw phy phy0 set antenna 0 0
$ ifconfig wlan0 up Zigbee
The RSI driver supports three ZigBee modes: End Device mode, Coordinator mode, and Router mode. After successful driver installation, the interface zigb0 should be created. This can be verified using the ifconfig command:
$ ifconfig zigb0 zigb0: flags=4098<BROADCAST,MULTICAST> mtu 1500

Bluetooth
The RS9113 supports dual-mode Bluetooth 4.0. Below is an example of a set of commands to successfully pair a Bluetooth device.
$ sudo bluetoothctl
