Re: [Bluez-users] rfcomm question 3

[Marco Trudel <mtrudel@gmx.ch>]

Hello Michael

Do I understand this right:

You have to control infrared devices like a television with your mobile
phone. The connection between your mobile phone and your pc is over
bluetooth and your pc then sends the infrared signals to the television, is
this correct?
You were able to connect from your pc to the mobile phone. Did you use
bluetooth? Which service do you connected to (from your mobile phone),
what's it's name?
Then you sent the menu for the remote control from your pc to your mobile
phone using at commands and got the choices you made on the mobile phone
bacck to your pc. Your pc then sent the answer to the television using
infrared?

Hope I understood this more or less correctly...

regards
Marco
