When I import the struct nmea::Nmea the program crashes on ESP32 about nmea

Hello and thank you for reporting the issue!

I have heard from Espressif systems that the NMEA structure has a very big memory footprint. It is very possible that just instantiating this structure takes all of your stack.

Could you please try and use the parse function instead of creating the NMEA structure?

Also you can check the size of the structure by using https://doc.rust-lang.org/core/mem/fn.size_of.html

You can also use the cargo size to gain a bit more information about how much space you will have left on the device RAM.
