I'm trying to connect gps (Garmin gps 19x hvs) to openimu300zi. Not yet, I'm not getting any information while gps is connected.

I downloaded the INS application from the site“https://developers.aceinna.com/code/apps” and only changed the condition(baudrate = 38400, type = NMEA_TEXT)s shown below.
(GPS messages were checked in the serial viewer program under the conditions above.)

GPS is connected to P2 section (tx, rx, gnd, vcc), and all P1 section jumpers are all ON below.

When I checked this function(parseNMEAMessage), the wrong message was being sent, not the original GPS message.

What should I do to get the exact GPS information?
