Has anyone managed to get (signal strength) rssi information for bluetooth in c# or processing using the fireplug rn-usbx?

By now, you should know the drill. We know what Arduinos are (the standard ones, anyway). Other devices should come with links.
oh sorry the usb bluetooth adapter info is here http://www.coolcomponents.co.uk/catalog/product_info.php?cPath=25_63&products_id=391
I think it could be more of a c# question, ive done some google searches but there seems to be alot of conflicting information.
I'd start with firing a complaint off to Cool Components, telling them to fix the links on their product page. If they elect not to, I'd send the stuff back, and demand a refund.
They can't expect you to properly use the stuff they sell without proper documentation. Broken links do not constitute proper documentation in my book.
here is a new link, http://www.rovingnetworks.com/products/RN_USB_X
there is nothing in the datasheet for rssi although I think there is link strength data available if you connect in command mode.
I think I have to do it through the windows api but a little unsure how to go about it in VS2010 with c#
How are you using the device now? If, on start-up, you enter command mode by sending serial data to the device, you can then send serial data to the device to enable link quality output (continuously). Exit command mode to allow data transfer. You'll then need to distinguish between data from the device and data through the device.
Before you go too far down this path, what is it you expect to get from the link quality/RSSI information? Not distance, I hope, since RSSI and distance are not anywhere near a linear relationship.
Just now the device sits in my greenhouse outside and gathers environment data, when i load the software it gets all the historical data it has been storing in eeprom, saves it into an sql database, then clears the eeprom, i then graph everything out using zedgraph. It also sends out a live stream of data every 10 seconds for live graphing and max min values and time. Your right though its probably not worth having some sort of a meter, I have set everything up as cable replacement so I dont even need to connect to the device because as soon as i put my BT dongle into the computer it just connects automatically. if it wasnt in range it wouldnt connect.
