>I have a small sensor board that passes data from a pair of sensors to a remote app less than 10 meters from the sensor location. This is currently done with a RS232 link. The link is two-way, in that the app requests data and the sensor board responds. There is no handshaking of any type. I would like to eliminate this cabled link by transmitting the data via bluetooth from/to the remote app. The link must be pretty reliable. It IS NECESSARY for the link to ultimately present the data to the app and to the sensor board as RS232 data. As usual, cost is an issue.

BT is probably serious overkill for this, but the availability of cheap Bluetooth USB dongles may
help (if you can figure out how to talk to them - not sure how standardised this is) - I'd look at
short-range 433/869MHz modules or possibly Zigbee.
