[Bluez-devel] AmbiCom BT2000C works with hciattach

[Bluez-devel] AmbiCom BT2000C works with hciattach

[Tony Lindgren]

Hi all,

Just FYI, there was some discussion here a while back on the 
AmbiCom BT2000C, which is different from the earlier BT2000 
models.

Well turns out it works fine with serial_cs + hciattach:

hciattach /dev/ttyS1 csr -s 57600 57600
or
hciattach /dev/ttyS1 csr -s 57600 460800
hciconfig hci0 up
hcitool scan
...

Sorry if this was already old news :) Please CC me on any 
replies, I'm not subscribing.

Regards,

Tony

how good these news are actually depends on what kernel you are using ;)

Send me the output of "dump_cis" and I will add a line to hciattach for
that. What is "hciconfig -a" saying?

Regards

Marcel

Hi Tony,

these are good news, because hci_uart and serial_cs are not working very
nice together with a 2.6 kernel. May you share some more information
about your system. For example lspci, lsmod etc.

Nice firmware version. Actually it seems we got an alternative for
PCMCIA cards and a 2.6 kernel.

Regards

Marcel

Sure, it's one of these cheapo emachines m6805 amd64 laptops. Running 
64-bit Gentoo testing. Bluez version: hcidump 1.8, bluez libs
2.7. Bluetooth is compiled into the kernel, PCMCIA is not.
