CustomFields When Blank

[DrJaymz]

$PFLAA,0,-45322,54013,2709,1,406CCE!EZY29QP,23,,145,-10.7,9*70

Example where field is blank (the field after 1500). $PFLAA,3,1500,,11,1,407076!GDFDO,,,,0.0,8*0B

When parsing using custom fields, when the field is blank I'm getting a value, which I think is whatever it was previously. Updated is true, age is 1ms so it thinks its parsed it. I specifically need to know when this field is blank for my application.

Am I being dumb here?

I tried for ages to get around this problem. So far no progress.

Are you printing customvalue.value()? I did a test program and it works as expected. Sketch: #include "TinyGPS++.h"

const char *str1 = "$PFLAA,0,-45322,54013,2709,1,406CCE!EZY29QP,23,,145,-10.7,9*70\r\n"; const char *str2 = "$PFLAA,3,1500,,11,1,407076!GDFDO,,,,0.0,8*0B\r\n";

TinyGPSPlus gps; TinyGPSCustom custom(gps, "PFLAA", 3); void setup() { Serial.begin(115200); Serial.println("Hello!"); Serial.print("Before processing,value is: "); Serial.println(custom.value()); while (*str1) gps.encode(*str1++); Serial.print("After first sentence, value is: "); Serial.println(custom.value()); while (*str2) gps.encode(*str2++); Serial.print("After second sentence, value is: "); Serial.println(custom.value()); }

void loop() { // put your main code here, to run repeatedly:

}

Output: Hello! Before processing,value is: After first sentence, value is: 54013 After second sentence, value is:

I'll close this, but we can reopen if you have more trouble.
