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. Is BT the way to go here? What alternate wireless solution(s) should I = consider?=20 Any enlightenment will be appreciated.
