[Bluez-devel] Problem With the Inquiry and RFCOMM conexions

[Sir Graham (Terra)]

[-- Attachment #1: Type: text/plain, Size: 451 bytes --]


Hi,

I have a problem with make a Inquiry and RFCOMM conexions at the same time and don´t understand why.....(with BlueZ).

Is It possible in the same module of bluetooth make a inquiry (independ thread) and RFCOMM conexions (4 o 5 conexions in independ threads)  
at the same time?

If I use diferent handles for this the call HCI to the module ... Is it independient? 

Have somebody any experience in this sense?

Regards,
Sir Graham.

this is a limitation of the hardware. What does "hciconfig hci0 version"
tell you?

Hi Marcel,

Thanks very much for you answer....

"limitation of the hardware"..?   I use modules BT 2.0 for this ....

Info of hciconfig hci0 version:

hci0:   Type: UART
        BD Address: 00:07:80:XX:XX:XX ACL MTU: 384:8 SCO MTU: 64:8
        HCI Ver: 2.0 (0x3) HCI Rev: 0xa42 LMP Ver: 2.0 (0x3) LMP Subver:=20
0xa42
        Manufacturer: Cambridge Silicon Radio (10)


The inquiry and the RFCOMM in blueZ have diferent handles. I understand t=
he=20
calls hci to module don=C2=B4t mixed ....

Why if I send data over RFCOMM channels the inquiry don=C2=B4t find any d=
evice?
I don=C2=B4t send any data, mantaint the conexion, the inquiry works with=
 any=20
problem.... =C2=BF=C2=BF???

The Inquiry works in a independient thread, and every conexion RFCOMM hav=
e=20
his own thread also....

Any idea?

Regards,
Sir Graham.

it is still the same hardware. The number of handles doesn't matter.

 device?

I can't answer this. You might get lucky and get an answer for the CSR
experts.

you can use as many handles as you like, but the underlaying HCI device
is still the same. It doesn't allow inquiries while you are connecting
to another device. However newer chips allow to run an inquiry while you
are connected (still not while connecting).
