GTMAI report is supported. This report is sent to backend server when analog input voltage enters predefined alarm range. To configure alarm parameters of analog input ports use AT+GTMAI command. Applicable for Queclink GV200 device.

GTLOC packet is supported. This packet contains device real time position and is sent to the server after long press of a Function Key button. Function Key should be previously configured to work in Location mode by AT+GTFKS command. Applicable for Queclink GL300M device.

New device supported: Queclink GV50M

GTDRM packet is supported: device removal alarm. To enable this alarm use command AT+GTCFG with bit 17 of Event mask activated. Applicable for Queclink GV50 device.

GTIFG report parsing fixed for Queclink GMT200 devices.

GTLBS packet is supported for Queclink protocol.

New device supported: Queclink GL50B Parsing of GTSTR and GTCTN packets is fixed for this device type.

GTAIF report parsing fixed for Queclink GL300M devices.

GTBPL report parsing fixed for Queclink GL520 and GL530 devices.

Queclink protocol updated: Device type GL100 is renamed to GL100M (changes was automatically applied to all existing GL100 devices) GL100 legacy device type is added for queclink protocol (this device has different messages format - messages end with '\0' character)

[Changelog] queclink protocol

bird

New fields for CV200 recorder_config setting: video_resolution_ratio_ch1, camera_flip, forced_event_audio_mask, rec_dur, rec_event, video_roi, camera_mono_mask, event_channel_mask, encoding_mode

Fixed recorder_config field names for CV200: video_quality_front renamed to video_quality_ch1, video_quality_inter renamed to video_quality_ch2, inter_camera renamed to rec_ch2

Fixed rec_time_ign_off range for CV100: min corrected from 0.5 to 3 minutes

bird

New settings added for CV5000: Multi Recorder Parameters (AT+GTMRS), Media tab; Multimedia Event Trigger Configuration (AT+GTEVT), Media tab

bird

Speed Alarm (AT+GTSPD) settings are now defined per device type for GV350M, GV58CEU, GV57CEU, GV305CEU and GV355CEU, each with its own documented value ranges. Report ID is now configurable on GV305CEU and GV355CEU.

Crash Alarm (AT+GTCRA) settings are now defined per device type for the same five devices, each with its own documented fields and ranges.

GNSS Jamming Alarm setting is removed for GV58CEU, GV57CEU, GV305CEU and GV355CEU — these devices do not support AT+GTGPJ.

FW Update setting is now available for GV355CEU only, and its Download Protocol and Update Type values corrected to the documented ones.

bird

gtcra_gv350m setting fields gsensor_pre/gsensor_post renamed to sample_period_pre/sample_period_post for GV350M, matching the documented Sample Period Pre/Post-Crash fields. Command output is unchanged; the new keys appear as the setting is re-read from each device.

bird

CV200 protocol support upgraded to V2.25.

New parameters in the ID authorization report (+RESP:GTIDA): driver.id.source, driver.id.similarity, event.timestamp.

Devices running firmware older than V2.25 must be updated for +RESP:GTIDA to be parsed.

bird

+RESP:GTDUC data usage report is now supported for GV500CG devices, registering report.reason, traffic.total and traffic.daily.

bird

New parameters for GTDSS event reports: adas.lane.departure.event (event 23, lane departure warning) for CV5000, and dsm.driver.abnormal.event (event 6, driver abnormal) for CV5000 and CV200.

bird

tacho.driver.weekly.driving.duration is registered per driver for GV355CEU, CV200 and CV5000 devices: tacho.driver.weekly.driving.duration.1 and .2. On vehicles reporting two drivers each driver's weekly driving time is registered under its own key.

bird

GV355CEU

CAN Report Expansion Mask1 bit 13 (Total Fuel or Idle Fuel Used Expand) is supported.
Total Fuel Used and Total Idle Fuel Used reported in kilograms register as can.fuel.consumed.mass and can.fuel.idle.consumed.mass (kg), in place of the gaseous-fuel parameters. Values reported in litres continue to register as can.fuel.consumed and can.fuel.idle.consumed.
Total Fuel Read from Vehicle's Computer (Mask1 bit 17) registers as can.total.fuel.counter, so it and can.fuel.consumed (Total Fuel Used) are reported independently.

bird

Queclink GB130MG: added beacon model 13 (MOKO L01A) and Eddystone beacon type support to +RESP:GTBID and +RESP:GTBIE reports.

gnss.jamming.status is no longer registered from the GTJDS report. The transition announced in June is now complete - GTJDS reports cellular network jamming, and its state is available as gsm.jamming.alarm.status. Devices reporting genuine GNSS jamming are unaffected.

bird

The deprecated tpms array sub-field low.sensor.battery.voltage.status is now removed for GB130MG, GV350M and GV620MG, completing the transition announced for 2026-08-12. Use sensor.battery.low.status, emitted alongside it since 2026-07-29.

bird

+RESP:GTERI reports with Bluetooth accessory data now register relay state for CV200, GB100CG, GV305CEU, GV310LAU, GV350CEU, GV500CG, GV56, GV57CEU, GV58CEU and GV75CG devices when bit 14 of the Accessory Append Mask is set. On these devices GTERI carries <Relay state> only; <Relay Config Result> continues to be registered in +RESP:GTBAA and +RESP:GTBAR.
