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

Fixed engine.ignition.status always false in GTFRI/GTERI reports for GV500MA devices

CV200 tacho bug fix:

A fix for downloading the memory file has been added. The bit mask described in the protocol had inverted values. The full requested file was loaded, only the overview portion; now it should contain all the requested information.
