Over the past couple days I have used the IAR Embedded Workbench to • implement
some enhancements and bug fixes for the standard NXT firmware.

Great job John. And thank you especially for CommExecuteFunction. I couldn't
believe that Lego didn't allow a way to make a Bluetooth connection from a
program. With your firmware modifications, I am able to do this now.

I have only tested BTON, BTOFF, CONNECT, and DISCONNECT, but I intend to
test more of the commands that are a part of this syscall. I will also post
my results on here along with the parameters and return values that I am
able to interpret. I encourage others to test John's changes as well to give
him the leverage needed to convince Lego to take the changes.

3 CONNECT(Param1, Param2)

Param1 - index of device to connect to

Param2 - connection (1 - 3)

Result - BTCONNECTFAIL (0x9500, 38144). This can occur if you try to use a
connection that is already in use.



   4 DISCONNECT(Param1)

Param1 - connection (1 - 3)



12 BTON()

Result: 0 - SUCCESS

RetVal: 0 - if already ON

        1 - if was OFF


   13 BTOFF()

Result: 0 - SUCCESS

RetVal: 1 - Always


A suggestion: it would be nice if the Name struct member of
TCommExecuteFunction were implemented so you could connect by name as well
as by index.

(...) That's great news, David. I'm glad that you are having success using the new CommExecuteFunction system call. I haven't had a chance to test it at all yet personally but I was very confident that it would just work seeing as how exposing it (...)
