I tried to connect my gps device is Megastek GVT-800 with servers located in vps, but why always provide information that String index out of range: -19 - StringIndexOutOfBoundsException (... <MegastekProtocolDecoder.java:166 <ExtendedObjectDecoder.java:39 <...)
This is for the information of traccar server error log

Thanks for the documentation. I have added this protocol to my backlog of new protocols.
