[Bluez-devel] detection phones with bluez

[Miron Cristian]

Hi,

   My issue manifests when in the same room there are
many bluetooth phones ( > 15 ). My application has a
bluetooth detection engine using a bluetooth dongle
device. I'm sending a OCF_INQUIRY command with
hci_send_cmd, with inquiry_cp.length = 10 (~13 sec I
guess) and when loop with poll function. My phone
detection engine doesn't detect all the phone. In the
first loop it detects some of them, then in the next
loop other phones and so on. 
   Is there a way to detect all the phone without
increasing the interval for scanning ? What is the
recommended interval for this? 

Thanks,
Cristian Miron

the easy answer is no. Increase the interval as needed.
