Tracker G900N supported protocol

Dear Concern,

I am trying to connect the G900N VTS tracker to traccar server. However I am unable to identify the accurate protocol for G900N VTS device.
And as per the communication protocol doc the below is the protocol format.

Start Bit
Occupy 2 bits Fixed value in HEX 0x67 0x67

Data Packet Length
Occupy 2 bits
Length = Protocol Number + Information Content + Information Serial Number
Information Serial Number

Please help me out if required i can share the communication protocol document which i have received from my Chinese supplier.

Thank you
