As mentioned elsewhere in the crate, we can use the COBS algorithm for framing. The cobs crate seems to implement it but probably needs a little work to support no_std.

The current frames seem to be written as:

1. a 0xff byte
2. a 2 byte length header
3. some data bytes

Unfortunately if the receiver becomes desynchronised (misses bytes) I think it'll be impossible to recover. COBS supports this.

I should have time to work on this shortly.

I used your crate to transfer data via TCP/IP and bluetooth rfcomm,
and u16 in general should be enough, but it too close to limit.

So is it possible to make length type to be generic parameter, not hardcoded?
