mgf-tele-teltonika 0.1.2

Teltonika Codec 8 / 8 Extended decoder + TelematicsProvider implementation — the first vendor package in the mgf-tele-* family, built on mgf-tele-core. Sibling of mgf-common under the mgf.* namespace.

mgf-tele-teltonika

Teltonika Codec 8 / 8 Extended decoder + a TelematicsProvider implementation for FMB/FMC/FMM devices. The first vendor package in the mgf-tele-* family — it builds on mgf-tele-core (the vendor-neutral seam) and never the other way around.

Extracted from PlasmaMapper's ingest path.

Install

pip install mgf-tele-teltonika

Use

from mgf.tele.teltonika import TeltonikaProvider, decode_avl_packet

# Decoder (pure: bytes -> mgf.tele.core.DecodedAvlRecord[]):
records = decode_avl_packet(wire_bytes)

# Provider (the mgf.tele.core.TelematicsProvider seam) in an ingest loop:
provider = TeltonikaProvider(imei_authoriser=my_registry_lookup)
handle = await provider.open_session(reader, writer)   # IMEI handshake
packet = await provider.receive_packet(handle)         # ReceivedPacket

What's in it

Name	What
decode_avl_packet / decode_codec8 / decode_codec8e	pure decoders → mgf.tele.core.DecodedAvlRecord; unsupported codecs raise mgf.tele.core.UnsupportedCodecError
TeltonikaProvider / TeltonikaSessionHandle	the TelematicsProvider concrete (TCP handshake → receive → ack → close)
mgf.tele.teltonika._crc.crc16_ibm	the CRC-16/IBM primitive
mgf.tele.teltonika._packets	wire-packet encoders (round-trip testing)

Codec 12 RX (command responses), 13/14/15, and 16 are not yet implemented and raise UnsupportedCodecError.

Design

• The decoder is a pure function (bytes → records); the provider owns the session lifecycle (the mgf-tele-core two-layer shape).
• Every malformed-frame / CRC / unsupported-codec / handshake / unknown- tracker / peer-close condition is a typed mgf.tele.core.TelematicsError subclass (rule EH-02).
• A 64 KiB frame cap (SH-04) bounds the unauthenticated ingest socket against a hostile data_field_length.
