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:#?}");
