Dell Edge Gateway 3003 Installation and Operation Manual

Ubuntu Network Manager

Network-Manager is a native Ubuntu Server connection manager. The application can be used to configure the Edge Gateway so that it is 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 wiki.archlinux.org/index.php/NetworkManager.

Connecting through WWAN

NOTE: For more information on configuring and connecting through WWAN, see 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 mmcli –L
```
Check the modem status and identify the primary port.
```
# sudo mmcli -m<0>
```
NOTE: <0> refers to the modem index number. Replace <0> with the modem index number after running the command at step 1.

Create a profile with the given primary port, for example, MBIM.

# sudo nmcli c add con-name test type gsm ifname cdc-wdm0 apn internet

Check the WWAN status.
```
# nmcli r wwan
```
Turn on WWAN.
```
# sudo nmcli r wwan on
```
Find wwan0 in the interface list.
```
# ifconfig -a
```
Enable the connection profile.
```
# sudo nmcli c up test
```
Check the Network Manager status.
```
$ nmcli d
```
Disable the connection profile.
```
# sudo nmcli c down test
```
Check the Network Manager status.
```
$ nmcli d
```

Enable debug mode for verbose logging

Adjust the systemd service.

# vi lib/systemd/system/ModemManager.service

Replace the line with the following:

ExecStart=/usr/sbin/ModemManager --debug --log-level=DEBUG

Re-initiate the service.
```
# systemctl daemon-reload
```

Connecting through WLAN

Show a list of network interfaces like eth0, eth1, wlan0, mlan0, and so on.
```
# nmcli d
```
Show a list of available wireless access points.
```
# nmcli d wifi
```
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 SoftAP (wifi-ap.snap)

Enabling the Software-enabled Access Point (SoftAP) can improve connectivity to wireless-access points by increasing available entropy and reducing the number of connection retries to clients.

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

Install haveged.
```
# sudo apt install haveged
```

Disable wpa_supplicant.

# sudo systemctl stop wpa_supplicant.service
# sudo systemctl mask wpa_supplicant.service

Detach from network manager.
```
# sudo nmcli d set wlan0 managed no
```
Install wifi-ap snap.
```
# snap install wifi-ap
```
Configure settings.
```
# sudo wifi-ap.setup-wizard
```
Check the status.
```
# sudo wifi-ap.status
ap.active: true
```

Connecting through SoftAP (hostapd)

Enabling the Software-enabled Access Point (SoftAP) can improve connectivity to wireless-access points by increasing available entropy and reducing the number of connection retries to clients.

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

Install haveged.
```
# sudo apt install haveged
```

Create your own /etc/hostapd/hostapd.conf. For example:

auth_algs=1
beacon_int=50
channel=3
country_code=ES
disassoc_low_ack=1
driver=nl80211
hw_mode=g
ht_capab=
ieee80211d=1
ieee80211n=1
interface=wlan0
require_ht=0
rsn_pairwise=CCMP
ssid=TEST
wmm_enabled=1
wpa=2
wpa_key_mgmt=WPA-PSK
wpa_passphrase=00000000

Disable wpa_supplicant.

# sudo systemctl stop wpa_supplicant.service
# sudo systemctl mask wpa_supplicant.service

Detach from network manager.
```
# sudo nmcli d set wlan0 managed no
```
Use hostapd to create an access point.
```
# hostapd /etc/hostapd/hostapd.conf
```

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

Switching between WLAN and Bluetooth modes

Adjust the mode from default 13 to 14 in /etc/modprobe.d/rs9113.conf.
```
# options rsi_sdio dev_oper_mode=14
```

Verify the operation mode.

# cat /sys/module/rsi_sdio/parameters/dev_oper_mode

Table 1. Operating-mode values for WLAN and BluetoothProvides the operating-mode values for WLAN and Bluetooth.

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.

# sudo apt-get install bluez bluez-tools

Prepare to pair MYSERVER and MYCLIENT.

# sudo bluetoothctl
[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.
```
[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
```
As of Bluetooth v2.1, SPP offers three methods of pairing devices, which are applicable on the Edge Gateway:
- Just Works
- Numeric Comparison
- Passkey Entry
NOTE: For more information about Bluetooth pairing, see blog.bluetooth.com/bluetooth-pairing-part-4.

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: rfcomm 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.
