Further documentation about the nom crate can be found at the docs.rs page and at the official github page.

Capabilities

It parses Codec 8, 8-Extended and 16 (aka TCP/UDP Protocol).

It DOES NOT parse Codec 12, 13 and 14 (aka GPRS Protocol), it MAY in the future.

It fails parsing if any of the following checks fail:

  • Preamble MUST BE 0x00000000
  • CRCs DOES NOT match
  • Record Counts DOES NOT match
  • UDP Un-usable byte MUST BE 0x01

Examples

Imei parsing

let imei_buffer = [0x00, 0x0F, 0x33, 0x35,
                   0x36, 0x33, 0x30, 0x37,
                   0x30, 0x34, 0x32, 0x34,
                   0x34, 0x31, 0x30, 0x31,
                   0x33
                   ];

let (rest, imei) = nom_teltonika::parser::imei(&imei_buffer).unwrap();

assert_eq!(rest, &[]);
assert_eq!(imei, String::from("356307042441013"));

Tcp Packet parsing

let buffer = [0x00, 0x00, 0x00, 0x00,
              0x00, 0x00, 0x00, 0x36,
              0x08, 0x01, 0x00, 0x00,
              0x01, 0x6B, 0x40, 0xD8,
              0xEA, 0x30, 0x01, 0x00,
              0x00, 0x00, 0x00, 0x00,
              0x00, 0x00, 0x00, 0x00,
              0x00, 0x00, 0x00, 0x00,
              0x00, 0x00, 0x01, 0x05,
              0x02, 0x15, 0x03, 0x01,
              0x01, 0x01, 0x42, 0x5E,
              0x0F, 0x01, 0xF1, 0x00,
              0x00, 0x60, 0x1A, 0x01,
              0x4E, 0x00, 0x00, 0x00,
              0x00, 0x00, 0x00, 0x00,
              0x00, 0x01, 0x00, 0x00,
              0xC7, 0xCF
              ];

let (rest, packet) = nom_teltonika::parser::tcp_packet(&buffer).unwrap();

assert_eq!(rest, &[]);
println!("{packet:#?}");
