Any one know how the default firmware on the X-NUCLEO-GNSS2A1 send the NMEA data?

Please explain how to get the NMEA data from the module. Is it works similar to Ublox modules? simply transmitting the data through the UART port or how?

    I expect it to stream NMEA Sentences by default, perhaps also have some binary messages, and configuration via $PSTMxx messages. Output via UART, query/read via I2C

    Hello @SSri.1 , 

    Yes as soon as you power up and flash the NUCLEO-F401RE firmware, the X-NUCLEO-GNSS2A1 will start giving the data on the UART interface. Baudrate from Module to MCU is 115200 and from MCU to PC Serial Port is 115200.You can try prebuilt binaries first.

    What issue are you facing?

    Regards,

    Yeah I got the data continuously through the UART interface after the powerup. I just messed with the jumper connections. finally I found the mistakes and solved it.
