You can use wifi if both devices are connected to the same network (see iNetwork library).

thanx erel

i looked in it and tried it but nothing happens when i send string

i used the same code install the app on my ipad and iphone4 both connected to the same wifi

do i need to change the host maybe??

(sorryi do it for the first time )

i could manage to send a string between the two devices like this

  Dim p As UDPPacket
   p.Initialize("Important message".GetBytes("UTF8"), "192.168.2.3", 18901)
   USocket.Send(p)

i just change the ip and put the other device ip and used the same port the that i intialize USocket in app start
and it worked

is it possible to get a list of all connected devices to the same wifi?? like this i could choose the opponent ip...

There is no simple way to find all the connected devices.

You should be able to use TCP as well. Your code was probably wrong.

ok erel, i solved it (was not easy)

i think there is a bug, when i send a word that include the letter "X" several times it arrived the first time as an "X" but then it arrived as "8" so i used only numbers and it worked (maybe it has something todo with UTF8??)

numbers allways arrived as sent...

thank you
