NemaMessage does not include empty GPGGA message

Hi,

I am using SharpGIS.NmeaParser Nuget 2.2.2 in a Windows 10 dot net core WPF project. All other messages are shown correctly except the empty GPGGA message. Seems that empty GPGGA messages are filtered out. Is this known?

Some sample messages from termnal:
$GPGGA,,,,,,,,,,M,,M,,56
$PTNL,GGK,133435.00,071502,0000.00000000,N,00000.00000000,E,0,00,0.0,EHT0.000,M7E
$GPVTG,,T,,M,,N,,K,N2C
$GPGST,,,,,,,,57
$GPGSV,,,79
$GPZDA,133435.01,15,07,2002,00,0067
$GPGSA,A,1,,,,,,,,,,,,,0.0,0.0,0.030
$GPRMC,133435.01,V,,,,,,,150702,,,N7E
$GPGLL,,,,,,,*7C
$GPGNS,,,,,,,,,,,,*4D
$GPGGA,,,,,,,,,,M,,M,,56
$PTNL,GGK,133436.00,071502,0000.00000000,N,00000.00000000,E,0,00,0.0,EHT0.000,M7D

Thanks,

The gga message looks incorrect. There should be a * before the last two characters. Only messages that are valid and with a correct checksum are raised

Thank you so much!

Hi,
Seems that empty GGA message "$GPGGA,,,,,,,,,,M,,M,,*56" was not showing either.

import pynmea2

msg=pynmea2.parse("$GPGGA,,,,,,,,,,M,,M,,*56")
msg
<GGA(timestamp=None, lat='', lat_dir='', lon='', lon_dir='', gps_qual=None, num_sats='', horizontal_dil='', altitude=None, altitude_units='M', geo_sep='', geo_sep_units='M', age_gps_data='', ref_station_id='')>
