I have a battery powered hand held data acquisition device that uses a = PIC 16F84 that sends small amounts of data serially to a RS232 via a = Dallas 275 line driver. As the device is used many times a day I am = experiencing plug and socket problems and I now feel I would like to = make this data link infrared, However as the amount of data is very = small (hundreds of bytes) and I will only need to transmit over a few = centimeters I do not see the need to implement a full IRDA spec link.=20 Question Has anyone seen or had such an application running if so: What hardware was used? (As there are many devices all with different = specifications). What battery life was obtained? And What sort of transmission speeds were achieved? Any help or pointers would be most appreciated.
