[Changelog] assistant-telematics protocol

bird

New Event Types supported:

Event Type 6 (Flight Mode) for ATL100: event.name with states Auto/Manual Enter, Auto/Timeout Quit
Event Type 10 (Humidity Alarm) for ATL100: humidity.alarm, event.name
Event Type 26 (Tachograph DDD File Upload): event.name with states Start/Success/Failed
Event Type 33 (Tilt Alarm) for AVT50: tilt.event

Event Types 4 (Free Fall), 5 (Tilt), 20 (G-Sensor Self-Calibration), 27 (Output Alarm), 28 (Delta AIS), 34 (BLE iBeacon Info) are now recognized and no longer generate unsupported warnings.

Unknown event types on non-matching device families now generate unsupported warnings for future implementation.

bird

New tachograph parameters added for AVT110/AVT111 devices:

tacho.performance — tachograph information bitmask (driver working states, card info, motion/direction/overspeed)
tacho.overspeed.status — tachograph overspeed signal
tacho.motion.status — tachograph vehicle motion signal
tacho.driving.direction — tachograph driving direction (0=forward, 1=reverse)
29 indexed tacho.driver.* parameters for Driver 1 and Driver 2 working time: remaining drive time, rest periods, daily/weekly driving durations, compensations, cumulative break/driving time, and more

bird

Fixed parsing of neighboring cell information for ABT110 devices.

bird

New parameter timestamp.key added for all device types — splits messages with the same integer timestamp using the packet serial number, preventing message merging in device storage.

bird

New parameter can.vehicle.battery.level added from Electric Info Mask 1 bit 12 (Only Battery Charge Level) for AVT110 devices
Bugfix in AT@CAN setting: Electric Info Mask 1 bits 12-15 field names corrected to match documentation — inverter_temperature_enable renamed to battery_charge_level_enable, removed dc_dc_converter_status_enable, regenerative_braking_enable, remaining_range_enable (bits 13-15 are Reserved)

bird

New NMEA2000 parameters for AVT110: can.vessel.direction, can.water.speed, can.water.depth, can.wind.direction, can.wind.speed
Bugfix in CAN setting: fixed NMEA2000 Info Mask bit ordering

bird

Bugfix in GCS setting for AVT20 and AVT50: fixed gnss_timeout minimum value (was incorrectly allowing 0, now enforces documented minimum of 1), fixed odo_initial_mileage decimal formatting, fixed initial_hour_meter_count normalization to HHHHH:MM:SS format.

bird

CAN Information Mask 3 (Data Mask bit 23) parsing implemented for AVT110 devices. New parameter: can.retarder.time.

bird

Fixed crash on AVT110 devices with PEO Polygon Fence enabled (Event Data Mask bits 21/23). New parameter geofences.ids.bitmask added for AVT110 — polygon fence (PEO) trigger status bitmask combining PEO IDs 1-32 (bits 0-31) and PEO IDs 33-50 (bits 32-49).

bird

Bugfix in GCS setting: fixed missing reserved field placeholders causing write command rejection for ABT110 devices

bird

+DFI (Device Full Information) report is now supported for AVT110 and AVT111 devices. New parameter: can.controller.hardware.version.

bird

Bugfix: AVT110/AVT111 devices with CAN bus sync enabled (firmware v5.03+) no longer crash-loop on connection
New parameter vehicle.model.id added to +RPT messages for AVT110/AVT111 devices (CAN Bus Sync ID)

bird

Fixed parsing of tachograph string fields (driver names, card codes, model) in RPT reports for AVT110 and AVT111 devices. Non-ASCII characters (e.g., European names with umlauts) are now correctly decoded.

bird

Fixed parsing of +DFI tachograph driver fields for AVT111 (firmware 000421+): corrected field order to tacho.driver.card.code.1 / tacho.driver.name.1 / tacho.driver.card.code.2 / tacho.driver.name.2, and added ISO-8859-1 charset decoding for driver name fields (supports Latin-1 characters such as umlauts).

bird

New device type added: Assistant Telematics AVT80.
Added parsing of BLE iBeacon info (ble.beacons), PEO fence and PEO fence overspeed alarm events, and PEO geofence status (geofences.ids.bitmask) for AVT80.

baja

Fixed CAN total-time parameters that were stored in the wrong unit. can.total.engine.idle.time and can.total.engine.cold.time now report hours (corrected values previewed in can.total.engine.idle.time.hours and can.total.engine.cold.time.hours); the originals switch over on June 17, 2026. can.total.cruise.control.time corrected to hours immediately.

EvgenyShatilo

Tacho update AVT110:

The ability to use a command to download tachograph data has been added.
- The full tacho file loading mechanism is supported.
- The format, file name, extension and all file metadata are determined automatically.
Authorization with a company card via TBA.

Note: The automatic download mechanism is currently unavailable (still under development).

namo

Assistant-telematics protocol is updated: Bit 21 of Data mask - RS485 Information Mask is supported.

Tacho update:

Added automatic download scheduler mechanism.
Bugs fixed.
Improved protocol compliance.

EvgenyShatilo

Tacho update:

fixed a problem where a command could be sent earlier than required.
improved work of the scheduler.
