Function decodePdu

decodePdu(bytes: Uint8Array): DecodedPdu
Decodes one complete, already-framed SMPP PDU.

Reads the header, then dispatches on command_id to parse the body, returning a DecodedPdu discriminated on command. The buffer must hold exactly one PDU whose command_length matches its size. Commands an ESME never has to parse the body of are rejected with a ProtocolError so the session can answer them with a generic_nack.
Parameters
- bytes: Uint8Array
  A buffer beginning with a single complete PDU.
Returns DecodedPdu
The decoded PDU.
Throws
If the header is malformed or the command is unsupported.

Since
1.0.3
Example
```
import { decodePdu, Command } from 'edgeport/smpp';

const pdu = decodePdu(respBytes);
if (pdu.command === Command.SubmitSmResp) console.log(pdu.messageId);
```
