Hi guys,
I have connected my BBB to PC (laptop) through ssh using USB. Also, I have successfully measured and displayed temperature sensor values in the terminal. Thanks to your tutorial.
But now, I would like to transmit and display the temperature values from BBB to PC using Wifi by adhoc (without any access point). I can create an ad-hoc connection by changing /etc/network/interfaces in BBB but I am not sure how to proceed further (especially the protocols) to transmit and display the values in PC terminal.
I searched in google but I am not able to find a proper answer. It would be very helpful if you could suggest some links or information. I have Debian wheezy with lxde installed in my PC and Debian wheezy Kernel 3.8.13 in my BBB. Also, I have TP-LINK TL-WN722N wifi dongle for the BBB.
Many Thanks!!

Android calls it "wifi direct" so I googled "wifi direct debian" and got:

Re: Suggestions to implement data transmission through Wifi
Thanks Paul for the reply.. As said in my previous post, I can establish adhoc link between PC and BBB using wifi but I want to know the approach to send particular data from BBB to PC and plot a graph in PC. I hope I am clear..

Re: Suggestions to implement data transmission through Wifi
I guess there dozens of ways, wget, curl, ftp, scp, rcp etc. If you have a program on the BBB that opens a window with the data. you can display that window on the PC by doing your ssh with the -Y option on the PC and then starting that program from the PC. I may be missing your point, I'm thinking.

Another guess. :-)
If you have program called X on the BBB that outputs the current values, your program on the PC can capture the data from an "ssh user@ip X" command.

Re: Suggestions to implement data transmission through Wifi
If you only want to view the data then I suggest using javascript and the built in bonescript with webserver on the BBB.
See Simon Monk's book for details.
