reading values from SignalK Server using SensESP

[Colug0]

Hello,

I try to read position data from my SignalK Server to display them on a M5 Tough display. Reading a value like True Heading works but I have no Idea how to access latitude and longitude.

This is my code for reading the Heading

const char* sk_path = "navigation.headingTrue";
  auto* value_listener = new SKValueListener<float>(sk_path, listen_delay);
  value_listener->connect_to(new LambdaConsumer<float>([](float value) {
    M5.Lcd.setTextColor(YELLOW, BLACK);
    M5.Lcd.setCursor(0, 60);
    M5.Lcd.printf(" Head: %3.4f   ", value);
  }));

This is how I tried to get values for latitude:

const char* sk_path = "navigation.position.latitude";
  auto* value_listener = new SKValueListener<float>(sk_path, listen_delay);
  value_listener->connect_to(new LambdaConsumer<float>([](float value) {
    M5.Lcd.setTextColor(YELLOW, BLACK);
    M5.Lcd.setCursor(0, 80);
    M5.Lcd.printf(" Lat: %3.4f   ", value);
  }));

The position Data is stored like this:

What I am doing wrong?
