This has the same effect. In fact, it works better than switching trains on the inquirer because inquiry is quite inefficient and losing frames on a particular train can have a big impact on the likelihood of finding a device. Of course, this requires the other end to co-operate, so there's not a lot you can do on the inquiring side." Can you explain it more and how can i use interlaced inquiry scan on a Bluetooth 1.2 scanning device (HCI_write_inquiry_scan_type interlaced). are there any online reference that i can refer to.? =) Regards, Shukri --------------------------------- Do you Yahoo!?

Hi Peter,
 
You have stated this before:

"If you have a Bluetooth 1.2 scanning device, you will be able to use
interlaced inquiry scan on it (HCI_write_inquiry_scan_type interlaced).
This has the same effect.  In fact, it works better than switching
trains on the inquirer because inquiry is quite inefficient and losing
frames on a particular train can have a big impact on the likelihood of
finding a device.

Of course, this requires the other end to co-operate, so there's not a
lot you can do on the inquiring side."
 
Can you explain it more and how can i use interlaced inquiry scan on a Bluetooth 1.2 scanning device (HCI_write_inquiry_scan_type interlaced). are there any online reference that i can refer to.? =)

Hi there,
 
what I'm trying to do is that I want to speed up the discovery process.  As stated by Somil before, the device inquires 256 times or for 2.56 s using one Train and then switches to a different Train. There are two Inquiry Train (called as Train A or Train B).
 
What I'm trying to do is, i want to reduce the no. of times that the train must be repeated before switches to another train. For e.g. :
 
AAAAAAAAAAA.....[256x]..BBBBB...[256x]... (train A repeat 256 times then see train B)
ABABABABAB........... (this is what happen when we change Ninquiry=1)
 
this can speed up the discovery process. are there any command or some modification in the source code that we can alter to reduce the no. of Ninquiry of train A & B? ~:)
 
I've done the simulation under network simulator by changing value of Ninquiry=1, and i found that the discovery process can be speed up.
 
Regards,
 
Shukri
