WIFI+BLUETOOTH STERLING-LWB
In this section are reported the procedures how to use the Wi-Fi and Bluetooth on device Engicam. The driver for support of these modules are automatically compiled in the recipes engicam-test-hw.
AP MODE
Create the file "/etc/udhcpd.conf" that will contains the address range that will assign AP
# Sample udhcpd configuration file (/etc/udhcpd.conf)
#The start and end of the IP lease block
start 192.168.3.10
end 192.168.3.100
# The interface that udhcpd will use
interface wlan1 #default: eth0
Edit the hostapd.conf file
interface=wlan1
driver=nl80211
logger_syslog=-1
logger_syslog_level=0
logger_stdout=-1
logger_stdout_level=3
ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
ssid=softAP
hw_mode=g
channel=6
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_passphrase=12345678
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP
Launch this command for configure AP MODE
iw dev wlan0 interface add wlan1 type __ap
ifconfig wlan1 hw ether 00:25:ca:07:0d:a6
ifconfig wlan1 192.168.3.1 up
hostapd /etc/hostapd.conf -B
udhcpd /etc/udhcpd.conf
WIRELESS MODE
WIRELESS PROTECTED NETWORKS
Up the network interface
ifconfig wlan0 up
Scan wireless network
iw dev wlan0 scan | grep SSID
Set the wpa_supplicant.conf with the SSID and Password of the AP network wireless
wpa_passphrase SSID PASSWORD > /etc/wpa_supplicant.conf
Use wpa_supplicant to connect to the AP
wpa_supplicant -iwlan0 -Dnl80211 -c/etc/wpa_supplicant.conf -B
Launch the dhcp client to acquire the ip address
udhcpc -iwlan0
Test the connection
ping 192.168.X.XXX
HOTSPOT MODE
Create the file "/etc/udhcpd.conf" that will contains the address range that will assign AP
# Sample udhcpd configuration file (/etc/udhcpd.conf)
#The start and end of the IP lease block
start 192.168.3.10
end 192.168.3.100
# The interface that udhcpd will use
interface wlan1 #default: eth0
# DNS servers that connected devices will use. Use Google DNS.
opt dns 8.8.8.8 8.8.4.4
# The IP address of the access point
opt router 192.168.3.1
opt subnet 255.255.255.0
opt domain local
Edit the hostapd.conf file

Launch this command for configure HOTSPOT
udhcpc -ieth0
echo 1 > /proc/sys/net/ipv4/ip_forward

iptables -A FORWARD -i wlan1 -o eth0 -j ACCEPT
BLUETOOTH
Example of sending file via Bluetooth
hciconfig hci0 up
hcitool scan
sdptool browse "MAC"
obexftp -b "MAC" -B 12 -U NONE -p file.txt
