Here attached protocol documentation for Chinese device called JT808.
JT808 Vehicle Tracking Protocol
I have tried connecting with port 5015 (huabao), but there is an error in the log as follows:
INFO: [Tbd15b4aa] error - readerIndex(113) + length(126) exceeds writerIndex(113): UnpooledByteBufAllocator$InstrumentedUnpooledUnsafeHeapByteBuf(ridx: 113, widx: 113, cap: 113) - IndexOutOfBoundsException (... < HuabaoProtocolDecoder:691 < *:237 < ExtendedObjectDecoder:75 < ... < WrapperContext:102 < ...)
The following is one of the location information data sent to the server:

Looks like it's not compatible with the current implementation. They probably changes something and decoder needs to be updated to support the change.
Hello Antón, I have a similar problem. Can the protocol code be modified? If so, could you give me a guide on how to do it please
I already explained what needs to be done. If you have the skills, you should be able to do it. Please send us a pull request if you manage to update the protocol.
@MarcosZreal, were you able to update the protocol?
