nom-teltonika, easily parse the teltonika protocol

This package makes use of the nom crate to parse the binary packets.

Capabilities

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

It DOES NOT currently parse Codec 12, 13 and 14 (aka GPRS Protocol), it MAY does so 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

Features

A TeltonikaStream wrapper is provided to easily parse the incoming packets.

The following opt-in features are available:

• serde (ser/deser-ialization using the serde crate)
• tokio (async framework using the tokio crate)

[dependencies]
nom-teltonika = { version = "*", features = ["serde", "tokio"] }

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 Frame 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, frame) = nom_teltonika::parser::tcp_frame(&buffer).unwrap();

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

Or by using the TeltonikaStream wrapper

let mut file = std::fs::File::open("tests/test.bin").unwrap();

let mut stream = nom_teltonika::TeltonikaStream::new(file);

let frame = stream.read_frame().unwrap();

println!("{frame:#?}");
