I wanna make a serial connection a wireless one,

it's 57600 baud

and I'm using matlab for the desktop side of the link

I don't like bluetooth (this was the original hookup) because the connection wouldn't stop dropping out - which I'm pretty sure was actually a windows problem with the bluetooth drivers for the dongle I was using

does anyone have any suggestions for a replacment?

I was thinking maybe these: (WRL-00713 & WRL-00705)

but they dont look all that simple... anyone have experience with them?

what would I have to do to get them to operate @ 57600 ?

thanks for any info

What if you were to use a serial bluetooth module for both ends of the link, and attach it to the host computer with a usb-serial adapter? Kind of kludgy, but it would take all the (apparently pretty buggy) windows bluetooth drivers out of the equation...

I think it would be a simple matter to change the SPBRG setting in the WRL-713's firmware to have it talk at 57600, but unless there's something I'm missing, that arrangement won't do error or packet-loss detection and retransmission, so you'd have to deal with that yourself.

Zigbee's another option, if it can provide enough data throughput for you.

you my friend, just suggested an absolutely spectacular idea...

...if only my project partners were around enough to suggest something as helpful... maybe then I (we) wouldn't be so behind...

thanks again!
