Bluetooth Module to PC
« on: March 31, 2010, 06:06:00 AM »
I just bought an UART bluetooth module,

I want to build circuit that turn led on and off but I don't know how.

Also I don't know how to connect this module to any physical device and how can I get the result of what that I send via the computer (I see the device as COM4)

It's possible to connect the TX and RX legs of the module to a regular COM port (TX and RX Legs)?

I will be happy to get any kind of help.

Thank you very much,
Etan hay.

Did you read the SoR bluetooth page? http://www.societyofrobots.com/electronics_bluetooth_robot.shtml

It might answer some of your questions.

Hello.

Both of the articles are about Axon kit.

I want to know if there is an option to connect the module to PC via COM port RX to TX and TX to RX.

Thank you very much.

Yes, that is exactly what happens in the bluetooth tutorial =)
The concept is pretty much the same with most atmegas.

To start, open up hyperterminal and connect to com4 if that's what it is and see if you can send/receive any data.

Have in mind that serial port is 15v and UART is ttl (5v). so you need conversion via max232 or similar chip.

Hi,

I just bought an UART bluetooth module,

You just redefined the term "Gross Overkill"  ;D

A simple set of TX/RX modules is close to Plug 'N' Play, while the Bluetooth will probably be mmore like Plug 'N' Pray.
But hey, as long as that LED are gonna shine  ;)
