v1.0.6

Experimental USB programmer update

• Config + TLS certs — program/verify configuration and upload/delete device PEMs
• Operator-supplied keyword unlock — --keyword or interactive prompt (does not discover the keyword)
• Linux + Windows builds; --no-reboot option
• Tested models documented: FMB020, FMC920, FMP100
• Does not flash firmware

v1.0.5

FT platform ioelements + experimental USB programmer

• FT / FTC / FTM ioelements — wiki Data Sending Parameters included so FT-series AVL IDs decode correctly (e.g. external voltage 800, manual geofence 155–157); Trip max kept at 1 so 0/1 still decode as bool
• Experimental USB Configurator programmer — standalone Linux CLI under experimental/usb_programmer (own go.mod); text + FMBX over USB; tested on FMB020 and FMC920 only — unsupported / write-capable

v1.0.4

ioelements catalog refresh

Full non-FT Teltonika wiki regeneration for AVL/IO definitions (not limited to a single device family).

• 88 supported models — adds ATC700/704/774, ATM700/704/774, FMB930 alongside the existing FM/FMB/FMC/FMM/FMU/TAT/… catalog
• Expanded AVL ID coverage (tachograph, LV-CAN, e-mobility, and related elements)
• FT / FTC / FTM platform intentionally omitted
• Wildcard (*) lookups with a known wire size prefer the most widely supported definition (keeps device-specific quirks such as FMB930 External Voltage model-scoped)
• Case-duplicate wiki rows collapsed (e.g. ATC HW-support naming variants)

Highlights

• Go module identity: github.com/sappsys/teltonika
• Codec 8 / 8E / 12–16 TCP/UDP decode & encode
• Human-readable ioelements catalog (wiki-refreshed, historical models preserved)
• Production-hardened fixes from operating Tracker247 (AVL/IO alignment, Codec 8E NX / signed element reads)
