[SOLVED][Feature Request]Wifi Key import via /boot/wifikeyfile.txt

[BuZz]

I will add the facility to use this configuration file from the wifi module. Cheers.

@BuZz That would be nice!

[BuZz]

@cyperghost implemented. Went with your naming convention.

That's a nice one! Works 100%

Test area:
I connected via Wifi SSH to Raspberry.
Imported wrong (default sample keyfile) >> Lost connection

Powered Off Raspberry, removed SD card, inserted in Windows mashine
Opend wifikeyfile.txt from FAT32 partition via editor (Notepad ++ is the better choice!)
Changed default entries to correct password.

Back to Raspberry, RetroPie Menu, Select Wifi
Imported now right setted keyfile >> Connections established!

Thank you so much! It was never so easy ;)
All without keyboard :)

I see my noob-code-style is totally converted to professional-style :)

One question to your latest coding...

 if [[ -f "/boot/wifikeyfile.txt" ]]; then
                        iniConfig " = " "\"" "/boot/wifikeyfile.txt"
                        iniGet "ssid"
                        local ssid="$ini_value"
                        iniGet "psk"
                        local psk="$ini_value"
                        create_config_wifi "wpa" "$ssid" "$psk"
                        gui_connect_wifi
                 else

The line create_config_wifi "wpa" "$ssid" "$psk" is to create a WPA network. Do you think it makes sense to add a third key to wifikeyfile.txt that sets the encryption? If the value is empty then WPA can be set as default. What do you think?

I think 99% of all WIFI networks work with WPA so it isn't a important feature.

[BuZz]

Sorry for late reply - must have missed this.

we could but as you say - does anyone use wep etc now ? It would be an easy change though so I'll make a note.

I know this one is marked as [SOLVED] but I have an issue with this function.

I tried it with image 4.1.
I created the wifikeyfile.txt with the standard Windows Notepad.
Windows seperates lines by 0x0D 0x0A. This causes a problem.

After importing the file the 0x0D is still attached to the ssid + psk and the connection fails.

I guess there are a lot auf Windows-Users and perhaps it is possible to remove the 0x0D to solve this issue.

@RetroProgramming use notepad++ with Unix line endings

[RetroProgramming]

I know what to do, but do you really want to tell every avarage Windows-User to install an extra tool to edit this tiny file?

[BuZz]

I will sort it.

Should handle CRLF files now.

Thanks for adding this great feature so we can configure wifi networks without a keyboard! At the moment you can only connect to one wifi network with the script, would it possible to reprogram it to define a number of wifi networks to choose from? I would like this feature as sometimes I want to take my retropie to a friend's house or use the wifi hotspot on my phone and this would save bringing a keyboard along.

Thanks again,
DP

[BuZz]

@DP That is beyond the scope of what I think would be useful for most people vs effort to implement. If you want to preconfigure your system for multiple wifi networks you can do so manually by editing /etc/wpa_supplicant/wpa_supplicant.conf and add some additional network blocks.

[DP]

@BuZz That's fair enough. Thanks for the suggestion, I was able to pre-configure my wifi networks manually although I had to set update_config=0 otherwise the file would get overwritten. It seems like a bit of an oversight that when switching networks it always asks for a psk even if it already provided within wpa_supplicant.conf but it works for my purposes now so I'm happy!

Thanks for your help!

[cyperghost]

@DP Sorry for being late .... you can modify the bash file I've created in first posting.
This will append wifi settings to wpa_supplicant. The PW will also be hashed btw...

The solution @BuZz created is a fine (to be true finest) way to connect to network. After network is established you can do anything you want.... for example create a bash file by yourself to add more networks and just put it in ES config menu :)

[RetroProgramming]

@BuZz said in [SOLVED][Feature Request]Wifi Key import via /boot/wifikeyfile.txt:

Thanks, looks good now.

[cyperghost]

For info:
you can use this side to create hashed keys
https://www.wireshark.org/tools/wpa-psk.html

Just enter SSID and PW and it will generate hashed key.
Knowledge is power!

Guys. There is no obvious explanation as to how or where to put this file. I see the scripts an that is it. I am not able to use the pi finder utility. I am trying to manually add the wifikeyfile.txt. How?

[herb_fargus]

@jseibert81 sure there is. Right in the docs:

[jseibert81]

@herb_fargus Thank you! I guess mine is not WPA, I will have to get a keyboard. Awesome forum.
