Re: D-Star DD protocol spec

TCP/IP is network layer and above.? It knows nothing of the underlying medium.

Something must govern at least MAC (CSMA/CA??) and functionality on the RF side of the radio.

There is NO PROTOCOL.? There are no retries, acknowledgements, timeouts, frame sequence numbers, etc.? Zip.? Nada.? Any of that stuff must be done by the equipment connected by the Ethernet cable to the ID-1.? Eg, TCP/IP.

Consider the RF connection between two ID-1 radios to be a (noisy, unreliable) wire.

Pardon if this has been asked/answered before.? I looked and couldn't find it.

Where can I find an English version of the protocol spec for DD?

I'm not talking about how to configure a radio.? I'm talking about how the DD protocol works over the air:? retries, acknowledgements, timeouts, frame sequence numbers, etc.

Thanks, Michael N6MEF
