We want to implement FMB640 for our own AVL project. But, where we can find technical info about protocol, datagram, etc? Or some samples source code in any language. Or whatever kind of technical help about low level protocol use model FMB640. The main thing we need to develop a listener tcp or udp, but it's really important to know datagram, hanshake, etc use gps.
Thanks!
