National Research Development Corporation -Bluetooth RS 232 interface module

RS232 is a widely used standard for communications between industrial medical and scientific apparatus. Many industrial, medical and scientific and devices are used to collect data in the field. Results are then downloaded to a computer for analysis over a downloaded to computer for analysis over a RS232 link.

The user has to carry around and RS232 cable, or perhaps more frequently, search for one when they return to base. A wireless alternative would make these device easier to use.
