Thread: bs2and gps

    Default bs2and gps

    i am trying to send gps data from stamp to computer.

    the rf transmitter allows a frame of 64 bytes and the output from etrex gps to
    stamp to rf is 65 bytes.

    the transceiver has "cts flow control" which will allow larger messages to be
    assembled on the other side, but must the remaining byte be somehow identified?

    can the gps info be reduced by one byte?

    thanks for any help

    There is no flow control from the GPS unit. I use a BS2p for GPS and buffer
    the GPS data into the scratchpad ram with the SPSTR modifier of SERIN.
