I'm using an old device (2006 - extremely trimmed embedded Linux) to get GPS latitude and longitude from an external receiver. GPS coordinates are displayed on device's LCD display. It used to work fine until the original GPS receiver failed. They replaced it with a new receiver but now it doesn't work anymore, all I see on LCD is: Latitude: - / Longitude: -.
I tried to see if the new GPS receiver is operational. And it seems the GPGGA packets are there. The old device expects GPGGA packets for parsing/processing.
char GPSLatBuf[12], GPSLonBuf[12];
int parseGPSData(char * gpsBuffer)
char * p;
char gpsQuality = '0';
if((p = strstr(gpsBuffer, "$GPGGA")) == NULL)
return -1;
memset(GPSLatBuf, 0, sizeof(GPSLatBuf));
memset(GPSLonBuf, 0, sizeof(GPSLonBuf));
p += 7; // UTC time
if(*p != ',')
p += 10; // Latitude
if(*p != ',')
memcpy(&GPSLatBuf[1], p, 9);
p += 10; // N/S Hemisphere
if(*p != ',')
GPSLatBuf[0] = (*p == 'N') ? '+' : '-';
p += 2; // Longitude
if(*p != ',')
memcpy(&GPSLonBuf[1], p, 10);
p += 11; // E/W Hemisphere
if(*p != ',')
GPSLonBuf[0] = (*p == 'E') ? '+' : '-';
p += 2; // GPS quality
if(*p != ',')
gpsQuality = *p;
if(gpsQuality == '0')
return -1;
return 0;
Expected to see non-void fields like before: +4916.4600 / -12311.1200 (just an example as I see nothing on display right now).

This is impossible to answer with the available information. You’ll need to know what the interface to the old receiver was, and how the new receiver behaves differently. Since you’ve not identified the new model, there’s nothing we can do to help. Even if you did specify it, there’d be a lot of questions to be answered. Have you obtained the programming manuals for the new device? If not, do so.

Hope this is not too late.
The idea is: the number of decimal digits of data inside GPGGA message is somehow specific to GPS module.
Hence, your code has an issue here, as it uses fixed offsets to search for latitude, longitude, etc.
It is easy to fix that: instead of using fixed offsets, you should search for the delimiter ("," in this case) using strstr() function.
Here's the corrected code:
int parseGPSData(char * gpsBuffer)
char * p;
char gpsQuality = '0';
if((p = strstr(gpsBuffer, "$GPGGA")) == NULL)
return -1;
memset(GPSLatBuf, 0, sizeof(GPSLatBuf));
memset(GPSLonBuf, 0, sizeof(GPSLonBuf));
if((p = strstr(p, ",")) != NULL)
p++; // there is UTC time
if((p = strstr(p, ",")) != NULL)
p++; // Latitude
memcpy(&GPSLatBuf[1], p, 9);
if((p = strstr(p, ",")) != NULL)
p++; // N/S Hemisphere
GPSLatBuf[0] = (*p == 'N') ? '+' : '-';
if((p = strstr(p, ",")) != NULL)
p++; // Longitude
memcpy(&GPSLonBuf[1], p, 10);
if((p = strstr(p, ",")) != NULL)
p++; // E/W Hemisphere
GPSLonBuf[0] = (*p == 'E') ? '+' : '-';
if((p = strstr(p, ",")) != NULL)
gpsQuality = p[1];
if(gpsQuality == '0')
return -1;
return 0;
I'm pretty sure this will solve your issue :)

This is impossible to answer with the available information. You’ll need to know what the interface to the old receiver was, and how the new receiver behaves differently. Since you’ve not identified the new model, there’s nothing we can do to help. Even if you did specify it, there’d be a lot of questions to be answered. Have you obtained the programming manuals for the new device? If not, do so.

Figure out which string is not parsable, generate a test case based on it and debug.

I thought about debug too, but it's an old device and it provides no debug info, no logs. Luckily we have the source code.

The code seem to be portable enough to be debugged even not on the target.

@JonathanLeffler: But afaik, GPGGA should be standard NMEA message, right? Or are there variations, different implementations allowed?
