tk103 packet
You have to check the protocol documentation.
Yeah just says it could be 8 bits after the course as IO State I'd have expected that to be 8 0s or 1s. Not 43.40,12
Are you sure you're checking the DW30 message type?
DW30 is not found in https://www.traccar.org/protocol/5002-tk103/KX402_GPRS_V15_EN.pdf
Under: 4.1 it lists the GPS location message - where I pulled that text from
And in: https://www.traccar.org/protocol/5002-tk103/TK103%20GPS%20Vehicle%20tracker%20user%20manual3.doc
Also not mentioned. So I'm not sure where in the "You have to check the protocol documentation." I am supposed ot be looking.
You have to ask your device vendor to provide the documentation for your specific device.
Curious. In the following decoded packet (from Testing suite)
What is the 43.40 in the 2nd to last position. It looks like it's right after the course. I also can't figure out the 12.
