Dell Edge Gateway 3003 Installation and Operation Manual

Ubuntu Network Manager

Network-Manager is a native Ubuntu Snappy connection manager. The application can be used to configure the Edge Gateway so that it's automatically-detected and connected to the network. The application can be used to configure multiple network devices.

A command-line utility nmcli is included with Network-Manager to support non-graphical user interface configurations.

NOTE: For more information about Network Manager, see https://wiki.archlinux.org/index.php/NetworkManager

Connecting through WWAN

NOTE: For more information on configuring and connecting through WWAN, see https://docs.ubuntu.com/core/en/stacks/network/network-manager/docs/configure-cellular-connections.

Check if a modem is present and identify the modem index number.
```
$ sudo modem-manager.mmcli –L
```
Check the modem status and identify the primary port.
```
$ sudo modem-manager.mmcli -m <x>
```
NOTE: <x> refers to the modem index number. Replace <x> with the modem index number after running the command at step 1.
Create a profile.
```
$ sudo network-manager.nmcli c add con-name test type gsm ifname <primary port> apn internet
```
NOTE: Depending on the return results from step 2, replace <primary port > after ifname with the actual primary port name.
Check the WWAN status.
```
$ network-manager.nmcli r wwan
```
Turn on WWAN.
```
$ sudo network-manager.nmcli r wwan on
```
Find wwan0 in the interface list.
```
$ ifconfig -a
```
Enable the connection profile.
```
$ sudo network-manager.nmcli c up test
```
Check the Network Manager status.
```
$ network-manager.nmcli d
```

Disable the connection profile.

$ sudo network-manager.nmcli c down test

Check the Network Manager status.
```
$ network-manager.nmcli d
```

Connecting through WLAN

Show a list of network interfaces like eth0, eth1, wlan0, mlan0, and so on.
```
$ network-manager.nmcli d
```
Show a list of network interfaces like eth0, eth1, wlan0, mlan0, and so on.
```
$ network-manager.nmcli d
```
Show a list of available wireless access points.
```
$ network-manager.nmcli device wifi list
```
Wireless connection with nmcli: Run the following commands and replace $SSID, $PSK, and $WIFI_INTERFACE with the variables for your environment.
- Connect:
```
$ sudo network-manager.nmcli dev wifi connect $SSID password $PSK ifname $WIFI_INTERFACE
```
- Disconnect:
```
$ sudo network-manager.nmcli dev disconnect $WIFI_INTERFACE
```

Connecting through software-enabled Access Point (SoftAP)

This feature depends on the wireless module and its associated driver to function as a wireless-access point.

NOTE: For more information on SoftAP, see https://docs.ubuntu.com/core/en/stacks/network/wifi-ap/docs/index.

Login to Ubuntu Snappy. Make sure that the system is connected to the internet.
Run the command to find the application from the Ubuntu Snappy Store.
```
#sudo snap seach wifi-ap
```
Run the command to install the application.
```
#sudo snap install wifi-ap
```
After snap is installed, run the command to check the status.
```
$ wifi-ap.status
```
Run the command to enable the access point and restart the service.
```
$ wifi-ap.config set disabled=false
```
The Wi-Fi-AP default SSID Ubuntu is now visible to clients.

To secure the Wi-Fi access point with WPA 2 personal, change the following configuration items.

$ wifi-ap.config set wifi.security=wpa2 wifi.security-passphrase=Test1234

The command enables WPA2 security with the passphrase set to Test1234.

Connecting through Bluetooth

This feature allows the system to connect to Bluetooth devices such as a Bluetooth keyboard.

Run the command to start bluetoothctl console.
```
#bluetoothctl -a
```
The bluetoothctl console opens.
Run the command to power on the Bluetooth device.
```
$power on
```
Register the agent for the keyboard:
```
$agent KeyboardOnly
$default-agent
```
Run the command to put the Bluetooth controller in pair-able mode.
```
$pairable on
```
Run the command to scan for nearby Bluetooth devices.
```
$scan on
```
Run the command to stop scanning after the Bluetooth keyboard is found.
```
$scan off
```
Run the command to pair the Bluetooth keyboard.
```
$pair <MAC address of Bluetooth keyboard>
```
Enter the PIN code on the Bluetooth keyboard, if needed.
Run the command to trust the Bluetooth keyboard.
```
$trust <MAC address of Bluetooth keyboard>
```
Run the command to connect the to the Bluetooth keyboard.
```
$connect <MAC address of Bluetooth keyboard>
```
To quit the bluetoothctl console.
```
$quit
```

Switching between WLAN and Bluetooth modes

Unload the WLAN/BT driver.
```
$ modprobe -r ven_rsi_sdio
```
Adjust the mode in /etc/modprobe.d/rs9113.conf
Reload the WLAN/BT driver.
```
$ modprobe ven_rsi_sdio
```
Verify the operation mode. Refer to the table for operating mode values.
```
$ cat /sys/module/ven_rsi_sdio/parameters/dev_oper_mode
```

Table 1. Operating-mode values for WLAN and BluetoothProvides the operating-mode values for WLAN and Bluetooth.
Operating mode value	Wi-Fi station	BT/BLE modes supported	softAP	Clients supported by softAP
1	X	N/A		N/A
1		N/A	X	32
13	X	Dual (BT classic and BTLE)		N/A
14		Dual (BT classic and BTLE)	X	4
5	X	BT Classic		N/A
6		BT Classic	X	32

Bluetooth Serial Port Profile (SPP)

Assumptions for MAC addresses of each BT adapter:

BT MAC(MYCLIENT): XX:XX:XX:XX:XX:XX
BT MAC(MYSERVER): YY:YY:YY:YY:YY:YY

Pre-requirements (for Debian-only, not required on Ubuntu Core OS).
```
sudo apt-get install bluez bluez-tools
```

Prepare to pair MYSERVER and MYCLIENT

$ sudo bluez.bluetoothctl -a
[bluetoothctl]# power on 
[bluetooth]# discoverable on 
[bluetooth]# scan on 
[NEW] Device XX:XX:XX:XX:XX:XX MYCLIENT 
[bluetooth]# scan off

Pair with each other. As of Bluetooth v2.1, Secure Simple Pairing is a requirement, and offers three methods of pairing devices, which are applicable on the Dell Gateway 3000 series:
- Just Works
- Numeric Comparison
- Passkey Entry
NOTE: For more information about blueetooth pairing, see https://blog.bluetooth.com/bluetooth-pairing-part-4.
```
[bluetooth]# agent on 
[bluetooth]# default-agent 
[bluetooth]# pairable on 
[bluetooth]# pair XX:XX:XX:XX:XX:XX <MAC Address of Device to Pair> 
[bluetooth]# connect XX:XX:XX:XX:XX:XX [CHG] Device XX:XX:XX:XX:XX:XX Connected: yes 
[bluetooth]# exit
```
Configure SPP.
Server Device
```
$ bluez.sdptool add --channel=22 SP 
$ ./rfcomm -r listen /dev/rfcomm0 22 
Waiting for connection on channel 22 
Connection from XX:XX:XX:XX:XX:XX to /dev/rfcomm0 <These lines will be seen when client comes> 
Press CTRL-C for hangup
```
Then, create a new instance of terminal to screen the data over bluetooth serial.
```
$ cat /dev/rfcomm0
```
Client Device
```
$ bluez.sdptool add --channel=22 SP 
$ ./rfcomm -r connect /dev/rfcomm0 YY:YY:YY:YY:YY:YY 22
```
Then, create a new instance of terminal to send data, for example, a new instance of ssh.
```
$ echo "test" > /dev/rfcomm0
```
NOTE: The rfcomm command is not available in this command. If required, you can copy the binary to the Edge Gateway from an AMD64-based system running Ubuntu 16.04 or above.
