Re: [Bluez-users] problem in parking device. bluez-libs 3.14, bluez-utils-3.14

Hi Mahin,

I am trying to park one bluetooth device.

First of all i have tried to use the bluez hci.c function
hci_park_mode() to park this device.
I have used the function in following manner 
      
 
       if( hci_park_mode(dd, handle, 0x200, 0x100, 25000) < 0 )
      {
         printf("\n Unable to park ...\n");
      }
       I am getting the handle correct here. 

These is the concerned part of code.. but I am not getting the device
parked... 
then I tried to check whether I can park it using hcitool cmd or not

This is the hciconfig -a output of my Master device

// Master

Slave has the same configuration and its Link policy is also   Link

These is the output of hcitool con

By searching into mailing list archieve ( link :
http://article.gmane.org/gmane.linux.bluez.devel/269/match=park )
I came to know that may be my parameters are wrong but I am not able
to understand what is wrong ..

One more thing.. hcitool con returns me handle as 256 ( hex 0x100 )..
Now when I am giving this as first parameter in hcitool cmd the
hex_dump function in 
hcitool.c prints only last two digits i.e. 00 . .. so I am a bit
confused that is my handle is passing correctly or not ?

the park mode support is always complicated. I would advise you to not
support it. Especially with non CSR based chips. However you have to run
hcidump -X -V to see what is really going on.

Regards

Marcel
