Bluetooth / Wifi Direct alternative wireless mobile transfer under GNU/Linux

Wireless Transfer

I recently had a lot of photos and videos that I wanted to transfer from my mobile phone. Sadly, my usb cable was clinically dead. I thought, hey! that thing can communicate wirelessly so why not use it?

Bluetooth? How fast is it?

First thing that came to mind was bluetooth. I knew that thing was kinda slow, but you know, it had to be  upgraded to revision 4.0 or 4.1 since my last phone. So, I went to check and on my phone it was version 4.2. Even Better ! and I thought even faster!

Setting up bluetooth under GNU/Linux

Blueman is a very nice utility that allows you to manage all your bluetooth devices.

sudo apt-get install blueman

Some configurations needed though:

nano /etc/bluetooth/main.conf

AutoEnable=true #uncomment this line for autodetection

Launch using:

blueman-manager

bluetooth wifi direct linux

Don’t make it easy.right ?

Once you open blueman, just setup by pairing your mobile to your computer. Its easy as a few clicks.

Bluetooth Speed – 7.9 Kb/s

Ok my peak speed was 7.9 Kb/s, surely I was doing something wrong. Probably hadn’t ‘unlocked’ my bluetooth’s potential. Looked again in config files. Noo !! That was kinda normal speed.

Speeding Bluetooth! 120 Kb/s

Did I find some magical wand? Secret config files? Kernel tweak? No No No.

Bluetooth is affected by distance. I just placed my phone very close to my laptop’s bluetooth. And the speed peaked to 120kb/s.

Yeah simple as that!

Still slow when you need to transfer 20GB worth of files. But I had reached somewhat of a bottleneck. If someone knows another way, please let me know. I have given up on bluetooth for files more than a few GB.

Wifi Direct

My mobile had some feature called Wifi Direct. That was the way to go. So how to set it up under Ubuntu ? I read the documentation, I had to move fast. As far as I remember, I had to tweak a lot of things on the phone, right into the kernel. This was too slow for me.

Wifi Direct complexity level – 7 out of ten ! No thank you !

Wifi File Transfer Free – 2.5Mb/s

What is this ? A nifty mobile app available on Google Play.

How does it work? This app simply creates a virtual server on your mobile. Then you access it using an url.

Fire it up as above on your mobile. Type the URL on your PC.

Beware: It’s available for all users on your Wifi network.

See and download your files in real time !

Recommendations

Bluetooth -Pictures. For few files around 1mb-4mb, bluetooth can be considered to be fast enough.

Wifi – Videos and tons of pictures ! Transfered around 20GB worth of videos in less than 10 minutes

You are welcome ! 🙂
