I've gotten the wifi to work, but bluetooth is eluding me.

I'm following the PDF instructions. I'm instructed to

Attach the bluetoth serial device via UART HCI

$ sudo hciattach /dev/ttySX bcm43xx

X is your UART port number that connect to Bluetooth module

which UART am I supposed to use? There's 31 of them!

    I just got my Up Core. I installed Ubuntu16.04, installed the drivers for WiFi, but Bluetooth is not being recognized.
    I did a quick search here in the Forum, it seems people have problem with Win10, I did not see anyone complaining about Ubuntu16.04 not seeing the Bluetooth.

    If I plug a USB dongle that has Bluetooth it works immediately.

    Is there a separate Linux driver for the Core bluetooth?
    Do I need to enable it at the BIOS? I did not see the option there.

    Thank you,

    Found it!

    Set Controller UART speed to 3000000 bit/s
    Flash firmware /etc/firmware/BCM43430A1.hcd
    Set Controller UART speed to 3000000 bit/s
    Device setup complete
    . Success![/pre]

    If this doesn't work for everyone, I made a batch file to test all the ttySs:

    for i in $(ls /dev/ttyS*)
    hciattach $i bcm43xx
    if [ $? -eq 0 ]
    echo "$1. Success!"
    (I don't know why the BBcode pre isn't keeping tabs. sorry)
