Hi krishna,

Hi Yoon,

Thank very much for your guidance. I followed the same procedure ...
You already did following procedure.
1. ofono-phonesim -p 12345 -gui ~/data/moblin.xml
2. sudo ofonod -nd 

And then, you need to type following command to power up modem(phonesim).
3. dbus-send --system --print-reply --dest=org.ofono / phonesim0 org.ofono.Modem.SetProperty string:Powered variant:boolean:true
  
I got below response....

Must use org.mydomain.Interface.Method notation, no dot in "phonesim0"

It seems you wrote the command with a bad syntax, there shoudn't be any white space between / and phonesim0, the command is:

dbus-send --system --print-reply --dest=org.ofono /phonesim0 org.ofono.Modem.SetProperty string:'Powered' variant:boolean:true

(I suggest using quotes rounding string constants).

Bye,
Dario.
