Hi,

     The poll() always return error :

     while ((n = 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)"

     Has anyone had same problem using poll() in embedded linux?

thanks a lot,

Al

Hi, there:
 
     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?
 
thanks a lot,
 
Al

Hi,
 
     How did you get name for other bluetooth device to find? Give the name
in codes instead of from /etc/bluetooth/hcid.conf ? Are other utilities functional
ok while disabling those options?
 
Thanks for helps,
 
Al

	Hi,

	When I am porting BlueZ to uCLinux, I found the same problem.
	I try with "select()" instead of "poll()", but I did not  solve the problem.

	I decided disable this option, and do not read the local name or other characteristics that I do not remenber.
	

	Regards.

Hi,
 
     Sorry, I described poll() problem incorrectly before. 
 
     The poll() always return 0, not error, meaning the descriptor is not ready before the timer expires.
 
      while ((n = 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)"

     Any advice/comment appreciated!
 
Al
