Bluetooth network bandwidth?

Archived from groups: comp.sys.palmtops.pilot (More info?)

Hi,


I'm trying out PocketTunes on my Zire72. The Shoutcast streaming feature
is really a killer feature. However, 128Kbps network streams seem to be
too much to handle for the Bluetooth connection, the stream breaks up
every few seconds.

I looked in the Bluetooth connection details and it says 115.200 bps,
which would, indeed, be too slow for 128K streams. 64Kbps streams work
fine. I'm using a Sitecom Bluetooth USB adapter connected to a laptop,
which, in turn, uses a broadband connection(with plenty of bandwidth).

Actually, I get the same problem when I try Softick PPP and the mini-USB
cable. Now I would expect a cable connection to offer plenty of
bandwidth, but it also stutters with 128Kbps streams, while 64Kbps works
fine.

Am I expecting too much? Do you really need WiFi to get the required
bandwidth?

Secondly, is it possible to automatically enable/disable Bluetooth
whenever the network connection or virtual serial port is opened/closed.


Regards

Some years ago it seemed it was because of using an UART to handle the
communications, thus limiting the speed to 115kbps. I don't know now, but I
guess the device's design were not changed on this aspect.
