Hi,
I found this email from last Dec. I have the similiar problem.
=20
I'm trying to port BlueZ on embedded uClinux. Kernel part seems ok =
so far.
For the HCI utility on user space part, I first have /hci-lib and =
/hcid
compiled to hcid. Then have /hci-lib and /hciconfig compiled to =
hciconfig.
Copy two applications, hcid and hciconfig, to ramdisk. Also I have =
hcid.conf
copied to ramdisk /etc/bluetooth/
After boot up, run hcid, then hciconfig hci0 up to bring up the =
device.
MAC address is read correctly. But when running hciconfig -a, it can't =
read local name correctly.
Are those steps correct? What do I miss?
--------------------------------------
If I rn hcid -n to see the printout:
/>hcid -n
hcid[18]: Bluetooth HCI deamon
hcid[18]: Starting security manager 0
---------------------------------------------------------------
/> hcid
/> hciconfig hci0 up
/> hciconfig -a
hci0: Type: USB

Can't read local name on hci0: Connection timed out (110)

/>
-------------------------------------------------------------------------=

The poll() always returns error :
while ((n =3D poll(&p, 1, to)) < 0) in funcion int hci_send_req () =
(file: hci.c) results in "Can't read local name on hci0: Connection =
timed out (110)"
Best Regards,
Al
