I read the FM63_FMB63_Protocols_V0.20.pdf manual describing this strange protocol, it doesn't say how to convert the 4 byte lat/lon fields into proper decimal coordinates... The formula they presented is (d + m/60 +s/3600 +ms/3600000)*p

However assuming d is byte 0 and milliseconds is byte 3 it doesn't give the correct result...

Can somebody please shed some light on this ? These codec8/16 protocols are VERY poorly documented.

(@Teltonika engineers why not just use ASN.1 with BER/DER? Proven and simple...)

Many thanks.

One more thing, I noticed that there is a firmware version 03 but that appears on the AVL list but I don't know where to get it.

Can you please point to the Firmware files and matching Configurator?

Thanks

I was able to solve it, apparently I need to take the 4 bytes as int and divide by precision=10000000 .

I am still in need of the latest firmware version and Configurator,  for FMB630. The latest one I was able to find is FM6300.00.02.117.e  it doesn't have the extended AVL support...

Where can I find 00.03.xx series ???
