Re: [Bluez-users] mx27, csr and bluez: initialisation timed out

Thanks for the hints.

hciattach, most of the time, does not work:

	peter@linuxpc:> hciattach /dev/ttyS0 bcsp
	Initialization timed out

On one occasion, which I cannot reproduce, hciattach actually worked to 
some extent:

	peter@linuxpc:> hciattach /dev/ttyS0 bcsp
	peter@linuxpc:> hciconfig
	hci0:   Type: UART
	        BD Address: 00:00:00:00:00:00 ACL MTU: 0:0 SCO MTU: 0:0
	        DOWN
	        RX bytes:15 acl:0 sco:0 events:0 errors:0
	        TX bytes:8 acl:0 sco:0 commands:0 errors:0

Any subsequent call to download the psr file failed:

	peter@linuxpc:> bccmd -t hci psload my.psr
	Device not available
	peter@linuxpc:> bccmd -t hci -d /dev/ttyS0 psload my.psr
	Device not available

I also tried to connect from a Windows PC using BTcli:

	btcli (built Jan 17 2007, 15:35:14)
	Version 1.24
	BSCP on COM1 at 38400 bps
	rba
	command_complete nhcp:0x01 read_bd_addr success ba 0x00025b00a5a5

Why is it impossible for the Linux host to communicate with the BC4-ROM? 
What do I miss?

Thanks for any hints,
peter
