The Gumstix SBC is available with a bluetooth transceiver from
Infineon (ROK 104 001/2R1A). Currently this has only been
tried using a rubber duck style antenna plugged in outside the
H2 case. Relocating the antenna connector or using a smaller
antenna could make this a more reasonable scenario.
Bluetooth model with antenna
So far we have only used the bluetooth capability to establish
a terminal connection from a PC using a USB bluetooth adapter
(Belkin F8T003 on Win2K with USB/Bluetooth software
installed). However, images can be transferred using rz over
this terminal connection, e.g.:
sh> cd /tmp
sh> rz
- use zmodem to send test.ppm.bz2 from host side via terminal
- file will end up as /tmp/test.ppm.bz2.
One thing to remember about rz is that it won't overwrite
files, so if you wanted to send an updated test.ppm.bz2, you
would need to delete the old one first.
There are lots of fun software projects one can imagine doing
using this interface. For example, H2 could be updated remotely
from some external device like a print server, weather feed,
or BT equipped cell phone.
We have experimented with obex file transfer over BT as well,
but have not gotten it working quite yet. It sure seems like
bluetooth is a bit flakey in general, even using a PC.
