Hi, I use cat /dev/ttyxx to check if there's data from pharos GPS. It did output some text data such $GP.... 0,50.0,50.0*05 But why the "cat" doesn't quit? It just hanged there unless I type "Ctrl+C" to quit. Is it correct? <ps> I checked some message and found while upper application uses gps_start_tx() and it did use CMD 52 to write pharos UART IER register. After that, it is hanged. BR, Victor |
