communication with Bluetooth

Vu

hi,

·could·you·tell me how to·create a bridge between 2 BS2e units by Bluetooth modules?

·I'm trying to control the Bluetooth module through UART link,
but the TTL high for BS2e is 5V and for the Ericsson Bluetooth module ROK101007 is 3.3V.

·Also, I couldn't find any sample code about·Bluetooth for BS2.

thanks

Do you have datasheets for that module?

If not, I'd suggest going for the EmbeddedBlue appmod instead.

It uses TTL level signalling, has an easy to understand instruction-set, and best of all, it comes with loads of sample code.

hi,

I attach the data sheet here.
I also wanted to use the EmbeddedBlue,
but·my lab has only those Ericsson Bluetooth modules·available

Can you give me some instruction on controlling that module.
Thanks alot

I've looked at the data sheet...

The command structure is not very well explained, and frankly doesn't look very easy to use.
(Commands are built with bits coupled together. It would help if you have experience in hand-coding assembly language)

It also looks as if this module uses slightly more power than the Embedded Blue while not active.

Maybe you can find more information somewhere in the SDK, possibly by looking at some of the C/C++ sources.

Hi,
I think I should find some sample code written in C/C++,
to·learn what·is being sent through the serial lines to the Bluetooth module
maybe then copy the sequence and use SERIN n SEROUT function of the BS2 to perform it.

· Hope it works...

and thanks alot for your help

see you
