I would say its even more convenient to monitor binary format, since its
more compact and could be read as a structures
// u-blox UBX protocol essentials
typedef struct ubx_header {
unsigned char preamble1;
unsigned char preamble2;
unsigned char msg_class;
unsigned char msg_id;
unsigned short length;
} my_ubx_header;
typedef struct ubx_nav_timegps {
unsigned long iTOW_ms;
signed long fTOW_ns;
signed short week;
signed char leapS;
unsigned char valid;
unsigned long tAcc;
} my_ubx_nav_timegps;
typedef struct ubx_nav_timeutc {
unsigned long iTOW_ms;
unsigned long tAcc_ns;
signed long nano;
unsigned short year;
unsigned char month;
unsigned char day;
unsigned char hour;
unsigned char min;
unsigned char sec;
unsigned char valid;
} my_ubx_nav_timeutc;
and so on...
