Bluetooth is really best suited for WPAN - Wireless Personal Area
This means it is great for replacing wires in a personal space. If you
at the original useage models they included such things as cellphone
laptop to cellphone connections, and other ad-hoc and simple network
This is really what Bluetooth is good at doing.
Yes, I understand. Our use of Bluetooth would be for a maintenance person in
the immediate area that wants to access one of the devices within range. Our
device is Ethernet based, and we do intend to support a wireless access to
the LAN, but some of our customers aren’t comfortable doing that (security
issues, I guess). In that case, the use of Bluetooth would be instead of a
cabled connection (RS-232?) to the device. I’m not yet sure that it makes
sense, but we’re trying to explore all our options.
Anyone know the answers to the questions?
BTW, the control device is probably PC/104 based, if that makes any
difference, and cost is a significant consideration.
You sound like you are doing a large area network and I would recommend
802.11. It works just like Ethernet, it is cheaper and easier to setup,
it provides 7-10x the effective bandwidth of bluetooth (802.11b), and it
supported under QNX today (devn-orinoco in 6.1.0 and devn-prism in an
release and probably on developers.qnx.com).

We’re considering several ways to do this, including Bluetooth wireless
devices. I’m awfully ignorant about Bluetooth, so…
Is there any kind of Bluetooth support by anyone for QNX 6?
What kind of interface device could be used (USB, serial, Ethernet,
Would a Bluetooth connection support the transport of standard TCP/IP
applications (http, ftp, telnet, custom socket application)?
Any wisdom here would be appreciated.
