| 13 | 8-bit | Status |
Typical statuses: 0x00 - SRP operation was successful 0x01 - Invalid Password - SRP verification failed due to mismatched M1 and M2 values 0x02 - Session request was rejected as there are too many active sessions on the server already 0x03 - Session options or timeout are invalid 0x05 - Timed out waiting for the other node to respond 0x06 - Could not allocate memory needed for authentication 0x07 - A request to terminate a session in progress has been made 0x08 - There is no password set on the server 0x09 - There was no initial response from the server 0x0A - Data within the frame is not valid or formatted incorrectly Atypical statuses: 0x80 - Server received a packet that was intended for a client or vice-versa 0x81 - Received an SRP packet we were not expecting 0x82 - Offset for a split value (A/B) came out of order 0x83 - Unrecognized or invalid SRP frame type 0x84 - Authentication protocol version is not supported 0xFF - An undefined error occurred |
| EOF | 8-bit | Checksum | 0xFF minus the 8-bit sum of bytes from offset 3 to this byte (between length and checksum). |
Examples
Each example is written without escapes (AP = 1) and all bytes are represented in hex format. For brevity, the start delimiter, length, and checksum fields have been excluded.
