Unable to connect intel centrino n135 wifi card to Intel galileo gen2

Hello mishra007,

 

Thanks for reaching out!

 

The N135 is actually the wireless card that I use with my Galileo. I used to set up the wireless interface by following Sergey's guide when I used the uclibc image but with the latest eglibc image (which can be downloaded from https://software.intel.com/en-us/iot/hardware/galileo/downloads) this is not necessary. I use connman to set the interface up. These are the steps I take from a fresh flash of the image:

 

systemctl start connman
connmanctl
enable wifi
agent on
scan wifi
services
#Check for the service name of your network and copy it
connect SERVICE_NAME_XXXXXXXXX
#Enter the network's password
quit

 

You can check the screenshot below of my Galileo's output during this process.

 

 

I hope this information helps you,
Pedro M.

Hi pedro!

THanks for replying but,when I run- systemctl start connman -- it just takes forever to run it! Here is the snapshot-

Currently I have connected intel galileo gen 2 with my router using an ethernet cable.And when I run that above command it shows multiple IPs assigned.For instance I have set static IP to my galileo using the arduino sketch prescribed by FGT long time back.And it was working perfectly fine.However when I run systemctl start connman,firstly it just keeps running forever,I mean it doesnt return any prompt(# symbol) and secondly,another IP gets assigned to my galileo(192.168.0.104). It is just strage,any idea what might be wrong?It has already taken 3-4 days!

Also when I ssh to 192.168.0.104,it results in a succesful connection.Now when I run connmanctl,it gets run. However scan wifi commands results in failure.I am attaching the pics below-

That is unexpected. I believe, this might be related to the image, therefore, I'd suggest you to download the image from https://software.intel.com/en-us/iot/hardware/galileo/downloads and set up your SD card as explained in https://software.intel.com/en-us/get-started-galileo-linux-step1 then try the steps above again.

Let me know.

You want me to download latest yocto pocky image right?210MB one?

I'd try with that one too, and I'd avoid using or downloading anything else, i.e. use the last image "as is" (without downloading any sketch to the Intel Galileo, in particular), which I think is exactly what Pedro M. suggested/did/exemplified above.

 

HTH,

Hi Fernando!

Thanks for replying! I download the fresh image as suggested by Mr Pedro and flashed it onto another sd card.Now when I run systemctl start connman,it results in success. I am able to follow all his steps until -- connect SERVICE_NAME_name_of_my_network. It throws this error-

PS:GotOurOwnWifi is the name of my network

Hi mishra007,

You are almost there, now, instead of entering the command connect SERVICE_NAME_GotOurOwnWifi, look for GotOurOwnWifi after entering the command services and check the ID next to it, it should look like this:

GotOurOwnWifi wifi_0cd229205aa3c_XXXXXXXXXXXXXXXXXXXXXX

Copy that ID and enter the command connect wifi_0cd229205aa3c_XXXXXXXXXXXXXXXXXXXXXX, now this should work for you.

Thanks for help I will try it once again. And FGT,can you kindly send me that arduino code once again,I mean the one that you sent me for setting static ip to intel galileo long time back.Actually my arduino IDE for intel wasnt working when I moved the folder containing intel arduino IDE to one of the window partitions(as my linux partition is almost full now)-- so I deleted it and installed a fresh and now I dont have your code!Damn should have saved it!. Sorry for the trouble!
But now it shows some error +111 or something in relocate_script.sh .I mean wtf!

I agree with Fernando, we should finish with the Wi-Fi issue before proceeding further. Just to clarify, you can also use the command suggested by Fernando directly on Linux, you would only need to remove the system(""), so the command would look like this:

ifconfig enp0s20f6 <your_fixed_ip> netmask 255.255.255.0

If the reason why you were using a sketch is because you need to run the command every time on boot, perhaps you'd be interested in reading this document: https://communities.intel.com/docs/DOC-111103.

I hope this helps.

Hi pedro!

              Ok,I installed the latest arduino IDE from arduino website and went on to further install add-on files for i586(i.e galileo). But now when I connect my galileo gen and try to flash the scannetwork code,I get the following error.In fact I get this error regardless of the code. I even checked if the file exists or now,but amazingly it does exist.I am simply baffled as to why it is throwing such an error.

Btw,this is the kind of error that I got when I tried installing the i586 package in arduino IDE for my gen 2.

I tried following your steps,to create a service routine in systemd/system directory. I named it staticip.service. But it still isnt able to set the static ip(192.168.0.110) to my galileo upon start. /home/root/static_ip.sh script works flawlessly though when I execute it! So I guess there is some problem with the way I have defined my service routine.

I am attaching the pics below.Also I have already made the /home/root/static_ip.sh executable.
I will summarize what I did,so that it become easy for you to follow-
1)Created a executable shell script in /home/root by the name static_ip.sh that has command to set static ip.
2)Then created a .service file in /lib/systemd/system directory by the name staticip.service

3) Issued the command systemctl enable staticip.service

4) Reboot

Try with the following:

static_ip.sh:

#!/bin/sh
ifconfig wlp1s0 192.168.10.12 netmask 255.255.255.0

static_ip.service

#!/bin/sh
[Unit]

Requires=wpa_supplicant.service

I tried this and it worked for me. Let me know how it goes for you.

Hi Pedro!

Thanks a lot for replying.I got it working after some trial and error.I changed the location of my executable bash script from /home/root to /usr/bin and then changed the ExecStart=/usr/bin/static_ip.sh and now it is working flawlessly! THanks a lot!
