Bluez + hcitool not able to scan
 
Hi,
I have put bluez 2.25 on my device. Since I was not successful in compiling Bluez 3.36 I have considered the older version.
I am able to pair with the device from computer but to be able to communicate through serial port profile I need to scan and ping the computer which i am not able to do.
well, i have attached few stuffs which i tried

Ps: sdpd doesnt seem to work.
should i create a node for the bluetooth device? or is it that the hcid.conf file in which anything is missing?

I am not 100% sure what you are trying to do with those commands, and your dmesg output seems to be indicating a whole lot of problems that may or may not have anything to do with the current issue.

If you are paired up with the device already, does it show the connection when you run "hcitool con"? You don't necessarily need to query the SDP records on the remote device if you already know it is running SPP (and know which RFCOMM channel it is bound to).

Have you tried simply binding an RFCOMM channel to the remote device and seeing that happens?

Code:
rfcomm bind rfcomm0 00:21:FC:FE:86:63

yeah I have tried that earlier
but it gives an error

First of all, you need to get the syntax correct for those commands.

For sdptool, you need to give it a Bluetooth MAC to inquire. The way you are trying to run it now isn't going to do what you want. You need to do:

Code:
sdptool search sp 00:21:FC:FE:86:63
But as I said in the last post, the SDP records don't really matter as long as you know the service is running on the other machine.

As for hcitool, again, you need to give it the MAC of the remote device, not the local device like you are trying to do.

Code:
hcitool cc 00:21:FC:FE:86:63
Though if you have already paired from the other side, you don't need to do this again.

As for the RFCOMM error, that means the rfcomm0 device node hasn't been created. Does this device you are working with have UDEV running? You might need to manually create the node:

Code:
mknod -m 666 /dev/rfcomm0 c 216 0
