[size=1][size=3]Dear Sir/Madam, first of all I must say that I am not a linux expert, just have been working with it for two months. I would like to configure the wlan0 on my SBC. I use a Ubuntu Linux on my PC and a Yocto image on my target boards. I would like to connect the SBC to the same router that I have at the Lab to which I connect my PC to browse. My idea would be to implement a server on the SBC to monitor parameters from an external browser. As a first step, I need to configure the wlan0 on my SBC, When I write iwconfi on my ubuntu terminal, I get this information about the router and the access that I have: wlan0 IEEE 802.11bgn ESSID:“Orange-9A08” Mode:Managed Frequency:2.432 GHz Access Point: 50:7E:5D:67:9A:0A Bit Rate=1 Mb/s Tx-Power=16 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=51/70 Signal level=-59 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:5 Invalid misc:2605 Missed beacon:0 If I write route, this is what I get (there is a router Livebox): alvaro@red:/$ route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default Livebox 0.0.0.0 UG 0 0 0 wlan0 192.168.1.0 \* 255.255.255.0 U 9 0 0 wlan0 what do I have to do on my SBC to have access to the internet by means of the same router? A part from that, could you give me any hint on how to install a webserver on my SBC … this will be the next step. Thank you in advance for you collaboration. Best regards, Alvaro Martinez ---

Hello Alvaro, The information you are looking for can be found on the Yocto’s First Step Guide on Digi’s website link below: [http://ftp1.digi.com/support/documentation/90001423\_B.pdf](http://ftp1.digi.com/support/documentation/90001423_B.pdf) 1- “Default network configuration” DEY allows you to configure the default network settings for your target’s image which will appear in the /etc/network/interfaces file. This is done in your project’s local.conf file using the following variables to define your default network settings: Where n is 0 or 1 depending on the number of available Ethernet interfaces in your platform. WLAN0\_STATIC\_IP = “” WLAN0\_STATIC\_NETMASK = “” To configure dynamic IPs, you can use the following configuration: ETHn\_MODE = “dhcp” WLAN0\_MODE = “dhcp” 2- “Adding features to your target image” Apart from the standard Yocto features, the DEY images introduce some new features that allow for a certain degree of customization ease. EXTRA\_IMAGE\_FEATURES = “” Most of the features are automatically selected based on the selected machine. For example, a machine that supports ALSA will include the dey-audio feature automatically. A list of new DEY features follows: • dey-audio: Adds audio support to a platform. • dey-gstreamer: Adds the gstreamer framework to a platform. • dey-network: Adds network applications and tools. You can configure some of the network applications in your conf/local.conf by doing: VIRTUAL-RUNTIME\_ftp-server = “vsftpd” VIRTUAL-RUNTIME\_http-server = “cherokee” VIRTUAL-RUNTIME\_network-utils = “net-tools” VIRTUAL-RUNTIME\_snmp-manager = “net-snmp-server” VIRTUAL-RUNTIME\_ssh\_server = “dropbear”
