Hi Tilen. Could you clarify please why lat/lon terms are not parsed in RMC parser?
if to take the first sentence from example.c
"$GPRMC,183729,A,3907.356,N,12102.482,W,000.0,360.0,080301,015.5,E*6F\r\n"
and feed to lwgps_process then position and utc time stay 0 although they are present in the sentence.

hgps lwgps_t {...}
latitude lwgps_float_t 0
longitude lwgps_float_t 0
altitude lwgps_float_t 0
geo_sep lwgps_float_t 0
sats_in_use uint8_t 0 '\0'
fix uint8_t 0 '\0'
hours uint8_t 0 '\0'
minutes uint8_t 0 '\0'
seconds uint8_t 0 '\0'
dop_h lwgps_float_t 0
dop_v lwgps_float_t 0
dop_p lwgps_float_t 0
fix_mode uint8_t 0 '\0'
satellites_ids uint8_t [12] 0x555555559081 <hgps+65>
sats_in_view uint8_t 0 '\0'
is_valid uint8_t 1 '\001'
speed lwgps_float_t 0
course lwgps_float_t 360
variation lwgps_float_t 15.5
date uint8_t 8 '\b'
month uint8_t 3 '\003'
year uint8_t 1 '\001'
p struct {...} {...}
stat lwgps_statement_t STAT_RMC
term_str char [13] 0x5555555590b4 <hgps+116>
term_pos uint8_t 3 '\003'
term_num uint8_t 12 '\f'
star uint8_t 1 '\001'
crc_calc uint8_t 111 'o'
data union {...} {...}

Could you explain what is the point please?

Global position data is parsed from GPGGA statement instead.

I have not worked with the real sensor yet. The way I see it is to configure chip on periodic send of RMC and disable other formats. Since RMC has everything needed: time, position and is position valid flag. So to save CPU resources it makes sense to read one sentence instead of two. But I'm not sure if it is possible on a real hardware though.
