Dear SLUGgers,
I have some farm equipment - two separate EID reader tools with
Bluetooth and two separate "receivers" - a serial dongle that plugs into
a weighing indicator/data recorder and a new version of the weighing
indicator/data recorder with Bluetooth built in.
The data doesn't get to these data recorders. That would be because
there is not a handshake set up between two sets powered up within
Bluetooth range.
I've run hcitool using a USB dongle to snoop on the devices with the
following results:

(I hope no-one uses this detailed information to hack into my cattle)
I've can't find a HOWTO that focuses on this sort of device - I guess
you city guys are more interested in PDAs and earpieces than dull little
serial dongles.
Does anyone know about this stuff? Ideally I could use the hci suite to
force a one-on-one relationship onto these Bluetooth sets.
Alternatively a promiscuous relationship would be fine - it's usually
likely to be at least 5 km to another Bluetooth device.
Thanks,
Kevin Shackleton.
