The bluetooth module can scan bluetooth devices nearby, however, failed to make connection with any of them, as shown 'Can't get device information: Host is down'.

The devices include my laptop, cell phone and a bluetooth mouse, and they were all turned on

What kind of devices are Claudie/COMPACT? hidd is generally used to bind up a HID device (ie: a keyboard/mouse). If Claudie/COMPACT are PCs, or similar, I doubt that they will respond to those kind of requests.

Can you use the l2ping command to validate the bluetooth link?

Regards,
Andre

Can you give some detailed information on how to use the l2ping command to make a connection between the bluetooth module and my laptop

l2ping simply validates that the layer-2 networking is working. It will not create a connection.

OBEX is the normal protocol for transferring files (Assuming that is what you want to do over bluetooth). Our package repository will be updated tonight to include the obexftp software. Once available, you should be able to run the following.

Have a look here for some more information:

root@snapper:~$ ipkg-cl install obexftp

The smiley faces are supposed to be : D (colon, capital D, with no space in between).

Yes, what I wanna do is collecting data from a serial port, then these data will be fed to the bluetooth module and then bluetooth module transfer the data to a paired PC. At the moment, I am trying to pair the module with my laptop, however, failed to make connection between them.

error apears when i typed

root@snapper:~$ ipkg-cl update
root@snapper:~$ ipkg-cl install obexftp

An error ocurred, return value: 4.

Check the spelling or perhaps run 'ipkg update'

any suggestion?
