Hi im not asking for anybody to tell me how to do this unless your kind enough to tell me im more intersted to know if it is possible and a pointer in the right direction.

I have an item that connects to my laptop with a D9 serial lead. Is it possible for me to use ttl to rs232 module and hc-05 or hc-06 bluetooth modules and possibly an arduino to make it wireless? Or do you know a way to do it. I have done lots of googling but not found anything to do the job. Perhaps I'm not searching the right words could anybody point me in the right direction thats if it is possible at all please.
Thanks
Bill

You may be able to use an RS232 to TTL converter to connect your device to an Arduino and use the Arduino to re-transmit the data to the PC using Bluetooth.

Without knowing more I can't say whether it would work. For example is there a proprietary PC program and could it be persuaded to communicate via Bluetooth? And is the nature of the "conversation" between the PC software and the device compatible with having an Arduino as an intermediary?

You need to be rather more forthcoming about the nature of the data and what you want to do with it. If it is plain vanilla SPP digital data being read on a PC terminal, Arduino should be able to receive, tramslate, and resend via HC-0x as Robin describes. One PC terminal is much the same as another. It is easier if Bluetooth is installed, like in a laptop, but getting a dongle going on a W7 desktop is OK.

Hi I have a radio scanner that uses a serial cable to program the radio. Is it possible to use HC-05/06 boards (or anything else) to link my laptop to the radio to make it wireless? I'm asking as I have searched but can not find any diy way to do it but I think it's possible spending around £50. I just take it if serial links are available there must be a way to do it. I'm only asking if it's possible not for you to tell me how to do it but if it is possible any pointers would be very much appreciated.
Thanks

What is sending the programming data? What is the distance? What is the data rate?

It is certainly possible, but to say how, we need more information.

It may be possible, but be aware that HC-0x are SPP (serial port profile) protocol - just plain vanilla digital data. You may need something more than that.
