this code works!
config:
M5Stack Fire with PSRAM DISABLED (g17/g16 conflict)
AT6558 GPS Unit attached at PORT C

Hi, I guest you are indoors and GPS Unit Example prints raw data needed to be transfer to readable data.

@ajb2k3 Guy, Thanks your reply!

[yellowelise]

I use tinygps++,
how can I change gps serial boud rate?
and how can I use 10hz sample rate?

[m5-docs]

@yellowelise

I think you need to reinitialize GPS Unit for changing baudrate.

[m5-docs]

@yellowelise

Write a reinit() function for reinitialization.

@watson
No baud in HardwareSerial but Baud in GPS module config, what is the correct NMEA string to config Serial Baud rate communication from GPS to HOST and what is the correct sentence to ser 10hz frequency?
es. $GPTXT.......

Hope those will help you.
