Bluetooth AT Commands (HCI Commands) How to Send ?

Hi,

I have bluetooth usb dongle connected to my PC running XP Windows.
How to send AT Commands to bluetooth usb dongle to set in discovery
mode
and read mac addresses of other bluetooth device nearby.

There is a good example from Linux minicom unfortunately it crashed
under Windows Hyperminal
wheneever I start it and try to type in anything from keyboard.

At the same time Widcomm and Bluesoleil bluetooth drivers/application
provided with bluetooth usb dongle work fine
and can discover nearby bluetooth devices and perform discovery
search.

Thanks.
Darius

I don't have any experience so far with connecting to GPS units
and issuing NMEA sentences. But I do have experience with
connecting to Bluetooth-enabled mobile phones.

Below is the log of a session with the Parani SD100, using
minicom (the Linux version of Hyperterminal). I have added
some comments. They are the lines beginning with "*".

I assume that a connection to a GPS unit would be very similiar,
except that NMEA sentences would be issued instead of
cellular-specific "AT" commands.

* start

ATZ

OK

* issue the command to scan for visible devices

Hi Darius,

This question is not 100% aimed at your topic, but I think you can help me.

What is the average time for establishing connection between two Bluetooth
units.
Timing start: The two units is in physical reading range.
Timing stop: Unit one read unit two ID.

I look forward to hear from you.

Flemming

I'm using a MotoROKR Z6m with BT DUN connection to a Nokia N800 Linux
internet tablet. From a cold start bootup until the phone beeps to
confirm the data connection is approximately 2 seconds. There are two
splash screens on the device. The first is a NOKIA on white background
with a little linear bootup guage across the bottom. When that guage
completes, Linux is loaded and a second splash screen comes up as Linux
loads its GUI and drivers off the internal non-volatile memory. The beep
happens when the second splash screen appears. By the time the GUI is
loaded 2 seconds later, opening applets are already connected to their
servers for new weather, updates, etc.

It's really fast!....lots faster than the wifi connection connects.

Connecting the tablet's File Manager to the ROKR's 2GB microSD memory
card over Bluetooth FTP is faster than waking up a USB hard drive to get
something, also about 2 seconds, too. Too bad the ROKR is incapable of
more than one BT connection at a time. It only uses one profile at a
time, disconnecting the internet DUN while the FTP is connected. If my
MotoROKR S9 stereo BT headset is connected, it won't connect to the
tablet at all on any function. You'd think Motorola, one of the largest
communications companies on the planet, could figure out how to make two
or 3 simultaneous BT connections, wouldn't you? Disappointing, very.

Thanks for your answer Larry,

I now realize that my writtenquestion was missing an important detail, so I
will try to include this detail

What is the average time for establishing connection between two
Bluetooth units.
Initial condition: The two units have never meet before.
Timing start: The two units is in physical reading range.
Timing stop: Unit one read unit two ID.

I look forward to hear from you all.

Best regards
Flemming

If I've understood you correctly, I guess the average time to be
several seconds.

I sometimes run a Parani SD100 in inquiry scan mode (looking for
discoverable devices). If I then make a nearby mobile phone
Bluetooth discoverable, it takes typically 3 to 5 seconds for
the Parani to identify it to me (12-digit Bluetooth ID,
user-friendly name, and 6-digit device class code).

This figure is an estimate taken from limited crude
experimentation.

If the distance is considerably greater, the Parani can take
much longer (maybe 10 seconds or more) to report the Bluetooth
ID and device class code, while sometimes reporting the
user-friendly name as "**UNKNOWN**".

Hi John,

Thank you for your answer, which was the answer I was looking for.

Some years ago I did a test with a bluetooth development board (bluetooth
version 1.1) and discovered the time to be similar to your test. Of which
version is your bluetooth devices?

Regards
Flemming

The Parani SD100 I use is a class 1 device, Bluetooth version
1.2 (class code 001F00).

The phones I tested are are a Siemens S55 (class code 720204)
and a Sony-Ericsson V600i (class code 520204). These are class
2, with the version not specified in the user manuals.
