Hello,
I'm new to using Bluetooth modules and would appreciate some guidance.
I'm connecting a Bluetooth module that has a UART interface to a
microcontroller, and I wish to use the BlueZ protocol stack to talk to
the module but I know nothing about how the protocol works. Can it be
configured to talk via UART to the module? Also, what is the minimal
set of functions one would need for simple data transfer between two
Bluetooth modules, no stereo audio, or other fancy stuff? My questions
will get more specific as I start understanding how this all works.
Thank you,
Jorge

Hi,
mebay you should know which protocols and which profile the Bluetooth module is working. If you plan to define a simple spec yourself, you can just use l2cap layer or hci layer interface.

You want to use the hciattach. I have used this on one of my MCF5282 designs
when talking to A7eng's bluetooth modules.
hciattach creates an hci device and brokers all requests over the UART to the
bluetooth module. From that point on you use everyday standard utilities to
manipulate the hci device that was created.
-A.

when your micro runs linux, then you should use Bluez. But from your mail
I suggest it doesn't. Than BlueZ won't be an real option because it
heavily depends on the operating system.
In the latter case you may
a) buy a commercial BT stack which is not OS dependend.
b) write your own stack (I don't think to use BlueZ as a base would be a
good idea)
c) use a BT chip / modul with build in stack
