Hi List,

somebody (me) with no idea about electronics try to do the following:

Talk to::

RB Bluetooth Transceiver Specfication:

- Bluetooth Chip:CSR BC417143 - Bluetooth Specification: v2.0+EDR - Transfer rate:2.4~2.48GHz unlicensed ISM band - USB Protocal:USB v1.1/2.0 - Modulation method:GFSK(Gaussian Frequency Shift Keying) - Transmitter power:?4dBm, Class 2 - Transmission range:20~30m in free space - Sensitivity:?-84dBm at 0.1% BER - Transfer rate:Asynchronous: 2.1Mbps(Max) / 160 kbps;Synchronous: 1Mbps/1Mbps - Security:Authentication and encryption - Support profiles:Bluetooth serial port- - Serial defualt setting:115200/N/ 8/1 - LED indicator light:Search(Power)/Connect - Input power:+5V~+12VDC/+3.3VDC 50mA - Work temperature:�20�C~+55�C

from my N+2.

I try the code from #Netduino Home Automation Projects' but no Chance.

I get only the red light(Power) to blink.

By the way, my Laptop has buildin Bluetooth, did i need a PC-Dongle as well??????

Any ideas

Thanks

Peter

Hi Peter, If you're just getting started, I'd recommend picking up a Bluetooth module which already has Netduino support. That way you can focus on your application...and then once you have that working you can tackle support for a new Bluetooth chip if you want. Chris

maybe this helps to get started.

seems your module is a simple bluetooth to serial converter too, basically it may have 4 pins to connect - VCC, GND, and Serial TX and RX. If you have a link or picture for your module may be easier to give some more detailed hints.

If your laptop has Bluetooth built in, you're good to go. Did you pair the Laptop BT with your Bluetooth module? for most modules I've seen so far (same/similar as the one I linked) they blinking fast while just powered and switching to steady light once bluetooth connection is establish. Then you can use a terminal program (Hyper Terminal has been part in earlier Windows versions) to use a Serial Connection over Bluetooth from your Laptop to the Netduino and back.
