Bluetooth, T637 & Linux

Now that I have finally got my Sony Ericsson T637 Bluetooth enabled phone, the fun has begun with setting up the bluetooth on my Gentoo laptop. I currently have a couple of bids in on ebay for a D-Link DBT-120 USB bluetooth dongle at the recomendation of John since he is using the same model and a similar phone on his Linux laptop and I know it works. John let me borrow his dongle for a bit to get my configs set up properly and make sure everything works before I actually get my own dongle.

The task was simple and the steps are fairly straight forward. I just had to recompile my kernel with the following options:

Device Drivers  --->
  Networking support  --->
    <M> Bluetooth subsystem support  --->
       --- Bluetooth subsystem support                                                           
      <M>   L2CAP protocol support                                                               
      <M>   SCO links support
      <M>   RFCOMM protocol support                                                 
      [*]     RFCOMM TTY support
      <M>   BNEP protocol support                                                               
      [*]     Multicast filter support
      [*]     Protocol filter support
      <M>   HIDP protocol support
        Bluetooth device drivers  --->
        <M> HCI USB driver
        [*]   SCO (voice) support
        <M> HCI UART driver                                                                           
        [*]   UART (H4) protocol support                                                               
        [*]   BCSP protocol support
        [*]     Transmit CRC with every BCSP packet                                                   
        <M> HCI BCM203x USB driver                                                                     
        <M> HCI BlueFRITZ! USB driver                                                   

I then rebooted my machine and emerged bluez-hcidump and bluez-tools. These provided the tools to poke and prod at the bluetooth dongle and search for other devices. blues-tools also provided an rc script that would start up all the necessary services on server boot.

I was able to get my phone and laptop talking to each other successfully. Next step will be to get rfcomm working so I can use my phone as a modem.
