Data corruption with UDP Sender

Fri Feb 15, 2019 10:33 pm

I'm having some issues with GpsGate spitting out partial GPS data via UDP. Running on a GETAC V110. Data is coming from COM2. When viewed in putty, data is clean and properly formatted. Configured GpsGate to be a UDP sender and the data is all over the place. My tracker server cannot parse properly because one report contains partial data followed by several more packets with the rest.

Clean data from COM2

Not so clean data from UDP port (each space delineates a new packet)

Anyone have any ideas about what might be causing this?

Thanks
