Aysch 2400 protocol suggestions

Hi all,

I will be sending data over a NBFM (Narrow Band FM) link up to 2400 baud.... Most Likely 2 level FSK.

I am looking for suggestions for the encoding and decoding of the data..

............ EG Manchester, Varying Pulse width, POCSAG, Staardard serial UART N,8,1, Caller ID style, SNAP

The data payload will be a 10 to 20 bytes.

What would you suggest for the encoding / decoding (using a micro at each end to code and decode) and any checksum / CRC.

The object is to discard any bad packets - no error correction needed.

Thanks in advance

Joseph

If you really use FSK, using UART data directly probably works.

Otherwise, I would suggest a pulse coding scheme like RC5, which also would work with ASK.
