Bluetooth to RS232

[Mike Scott-7]

I liked the K2 Bluetooth serial adapter project.

I Googled Bluetooth serial adapters (there are quite a few) and ran into an
A7 Engineering product.

http://www.a7eng.com/products/embeddedblue/serial/eb501-SER.htm

It is lower cost than the Socket Bluetooth adapter.
It looks ready to embed (doesn't have to be disassembled). It needs an
antenna. I wonder how I would mount an antenna on a K3; if it were internal
it seems to me that the case would severely impede signal.

Hi,

I don't know, but if you stay around your rig, I think you don't need much. With an antenna, bluetooth standard area is around 10m. So, I would guess that very near, within a meter, only a small wire should do the job. Just a guess....

And yes, this is really cool. Because I have only one serial port on my laptop, I can now use my SCS PTC-IIe with my K2 and have the control feature by using bluetooth. Less cable is something quite useful.

If you try it with this interface, let us know !!! :-)

I use the Blue Air adapter from Lynn Hansen KU7Q.
http://www.lynovation.com/

and was available as a kit some time ago.
there is some information on his homepage how to build one yourself.

There is a Pocket PC program to remote control the transceiver.
Works good with the K2, I did not yet plug it into my K3, but should behave
the same.

What is the latency and does it support control lines (DTR, CTS, etc.)?
