n900 bluetooth problems
 
Hi...been having problems with my Bluetooth...it does not detect active Bluetooth devices and it's not detectable...I've searched the forum and tried every solution suggested I.e deleting the Bluetooth folder in var/lib/bluetooth...it still won't come on...any suggestions...Will appreciate your help..

Re: n900 bluetooth problems
 
rule of thumb: the more effort it takes to get at least an idea how to solve, the more trivial the problem is ...

therefore: did you enable BT and set it to "visible"?

edit:

what do you get for

Code:
ps ax | grep bluetoothd
Code:
hciconfig
Code:
hcitool dev

(make sure to anonymize the MAC/BD Address before posting the output! that's the XX:XX:XX:XX:XX:XX string)

Re: n900 bluetooth problems
 
yes I switched on the visibility.

For the first command it gives me

/home/user # ps ax | grep bluetoohd
2178 root 2088 S grep bluetoohd

the second command gives me

/home/user # hciconfig
hci0: Type: UART
BD Address: XX:XX:XX:XX:XX:XX ACL MTU: 1017:4 SCO MTU: 64:1
DOWN
RX bytes:4054 acl:0 sco:0 events:105 errors:0
TX bytes:31592 acl:0 sco:0 commands:102 errors:0

and the third command gives me

/home/user # hcitool dev

Re: n900 bluetooth problems
 
OK. so, next step is to ensure the partner devices are working. Do you have another phone or something that claims it can see your N900? It's much eaier trying to pair something else with a screen (for feedback), which KBs and headsets etc. don't have.

Re: n900 bluetooth problems
 
i have a galaxy tab and blackberry...both are not recognising the device.Visibility is set to on and when searching on the galaxy tab its able to recognise the blackberry.The N900 isnt able to recognise any devices too.

try
Quote:
hciconfig hci0 up
and then
Quote:
hciconfig hci0
check if your device "hci0" were UP or not.
Quote:
dmesg | tail
then copy&paste&post messages to this thread.


I often use these commands when powering on my BT manually.
they're written on other maemo talk threads.it's worth to try them.

modprobe hci_h4p;
echo "00:11:22:33:44:55" > /sys/devices/platform/hci_h4p/bdaddr;
modprobe -r hci_h4p;
modprobe hci_h4p;
bluetoothd;
hciconfig hci0 up;
then

BD Address: XX:XX:XX:XX:XX:XX ACL MTU: 1017:4 SCO MTU: 64:1
UP RUNNING PSCAN ISCAN
RX bytes:9844 acl:0 sco:0 events:253 errors:0
TX bytes:75030 acl:0 sco:0 commands:246 errors:0

and for the final command

home/user # dmesg |tail

for the other process...

when i each the command modprobe -r hci_h4p i recieve

home/user # modprobe -r hci_h4P

neither does it recognise other devices nor is it recognised by other devices.

typo -- must be "bluetoothd"
you should see at least two lines of output -- one of bluetoothd itself and the second of your request.

something like this:

Code:

Nokia-N900-51-1:~# ps ax | grep bluetoothd
  940 root      3408 S    /usr/sbin/bluetoothd -n
 3357 root      4064 S    grep bluetoothd
Nokia-N900-51-1:~#
