Hi!

Is bluetooth expected to work on n900?

It looks like lock init is missing somewhere:

If I put the driver built-in, firmware loading failed. But I can't get
it to "hciconfig up" phase even with driver being modular. .. that
worked at one point IIRC.

any chance you can test this with "btmgmt power on" and have "btmon" run in the background. I wonder how far it gets with the init sequence.

Aha, but I did compile bluez-5.6, and it seems to have required tools.

Now it does:

I guess output just after boot will be more interesting?

if you manage to get a recent btmon then it will also decode all the the unknown packets. That would be interesting since it tells you exactly what mgmt sends and what also legacy tools do at any given time.

I really need to find my patches for the monitor ring-buffer and replay support so that you can keep these in kernel memory and configure this with a kernel cmdline option. In theory however starting btmon before insmod should be plenty to get the full trace.

The advantage of getting the initial ones is that with recent btmon, the vendor ones for Broadcom will be also decoded. It is just that at this point the vendor information is unknown.

Actually I just realize that this is special anyway. Since this is Nokia manufacture ID, but Broadcom vendor decoding. I think that we need to add some special handling for this to make sure user space is able to decode this properly.

Can you actually run btmgmt extinfo for me. I wonder if we are not having an issue here with the missing hdev->set_bdaddr support. It should show you support for the public-addr feature.

        if (btdev->man_id == NOKIA_ID_BCM2048) {                                 
                hu->hdev->set_bdaddr = btbcm_set_bdaddr;                         
                set_bit(HCI_QUIRK_INVALID_BDADDR, &hu->hdev->quirks);            
                dev_dbg(dev, "bcm2048 has invalid bluetooth address!");          
        } 

While we do this the btbcm_set_bdaddr might be actually empty.

config BT_HCIUART_NOKIA                                                          
        tristate "UART Nokia H4+ protocol support"                               
        depends on BT_HCIUART                                                    
        depends on BT_HCIUART_SERDEV                                             
        depends on PM                                                            
        select BT_HCIUART_H4                                                     

This is missing the select BT_BCM like what we have for the hci_bcm.c support.

config BT_HCIUART_BCM                                                            
        bool "Broadcom protocol support"                                         
        depends on BT_HCIUART                                                    
        select BT_HCIUART_H4                                                     
        select BT_BCM

Can you try to enable btbcm.ko module and load that first.

Regards

Marcel

Let me try:

pavel@n900:/my/bluez$ autoconf
configure.ac:4: error: possibly undefined macro: AM_INIT_AUTOMAKE
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.

configure.ac:24: error: possibly undefined macro: AM_PROG_CC_C_O

configure.ac:33: error: possibly undefined macro: AC_PROG_LIBTOOL
configure.ac:41: error: possibly undefined macro: AM_CONDITIONAL
pavel@n900:/my/bluez$ ./configure 
./configure: line 2189: syntax error near unexpected token `foreign'
./configure: line 2189: `AM_INIT_AUTOMAKE(foreign subdir-objects color-tests silent-rules'
pavel@n900:/my/bluez$ 

automake; autoconf results in less warnings out of autoconf.

In the end I just deleted the offending line.

But then it ends here:

./configure: line 4043: AM_PROG_CC_C_O: command not found
./configure: line 4044: AC_PROG_CC_PIE: command not found
configure: error: cannot find install-sh, install.sh, or shtool in "."

That was my fault, not kernel fault. I just relied on scrollback
buffer, and it was not big enough.

Aha. Ok, I guess I can test out the patches... if I manage to compile
it. Adding a hint how to compile from git (-> configure not present)
would be nice.

Actually, I guess I can just make it build-in. But I'm not sure how it
is supposed to help: I'd expect undefined symbols on broken
dependency, not silent failure.

Thanks,

you have you tried ./bootstrap or ./bootstrap-configure?

you can hack btmon to treat Nokia ID 2 as Broadcom ID 15 and then you would see the decoding.

The helper modules are designed to be selected. So they fail gracefully if not. So this is just a bug. Make sure to have btbcm built-in or btbcm.ko available.
