I've got 2 Apple Powerbooks (17" and 15" TiBooks), both completely
up-to-date on firmware and software updates, with built-in Bluetooth.
I want them to listen for incoming Bluetooth connections and take some
action, so I used the Bluetooth Serial Utility to create a
'/dev/tty.blueproxy' and then just 'cat /dev/tty.blueproxy' and see the
incoming data when a connection happens.
The odd thing is, this works fine on the 17" Powerbook, but on the 15",
the open(2) call blocks forever (inspected through ktrace), even though
the L2CAP baseband connection is successfully formed.
Can anyone suggest any reasons why the open(2) might block? This used
to work on the 15" PB as well, but things have been a bit odd since the
most recent firmware update. Note that I have done the PMU reset, and
that iSync and the Address Book SMSing works just fine on both laptops,
and Bluetooth configuration setup is exactly the same. If anyone has
any ideas on how to debug this, I'd appreciate them.
