[Bluez-users] connecting linux laptop to a three-wire RS232 device via bluetooth

[Russell Senior]

I am looking for hardware recommendations for both ends of a bluetooth
link between a Linux (kernel v2.6.11) laptop and a serial DCE device
(9600 baud no-flow-control three-wire RS232).  I am assuming a USB
part (the laptop has a USB 1.x port) for the laptop and some kind of
serial-bluetooth converter for the device end.  We'll need to provide
battery power (it is a mobile application and won't have line power)
to the serial-bluetooth converter.

I'd like recommendations on both parts.  I think we'll need Class 1
devices for the range.

For the serial-bluetooth converter, we have looked at the: Brainboxes
BL-512; the Free2Move F2M01C1; the BRADATECH BlueSerial Adapter; and
the Digi Wavespeed/S (we found less information on this one).

The only lead I have on the USB side is that we probably want a CSR
chipset (??).  Can someone point me at some of those?

Thanks very much!

I didn't tested any Bluetooth-Serial converters, but for the laptop
equipment you should really get a CSR based USB dongle. You may simply
go with the D-Link DBT-120, because this is known to be upgradable to
the Bluetooth 1.2 standard.

Regards

Marcel

Turns out (a couple just arrived) these are Class 2 devices.  Can you
point me at a Class 1 (100m) USB device?

BTW, how do the features hex decode on
<http://www.holtmann.org/linux/bluetooth/features.html>

Thanks!
