Interfacing Grove GPS Air530Z with RPi

[PJ_Glasso]

Hi there,
Well NOT a direct answer to your observations, but a good starting point for some,

Xiao Nrf52840 Sense w/ GPS Air530 & Expansion Board

Here is another basic example moded from original. Alternates the GMT time, Location and Number of SATs acquired. HTH GL PJ #include <Arduino.h> #include <U8x8lib.h> #include <Wire.h> #include <TinyGPSPlus.h> static const int RXPin = 6, TXPin = 7; // 6, 7 static const uint32_t GPSBaud = 9600; //TinyGPSPlus object TinyGPSPlus gps; //Display object U8X8_SSD1306_128X64_NONAME_HW_I2C u8x8(/* clock=*/ PIN_WIRE_SCL, /* data=*/ PIN_WIRE_SDA, /* reset=*/ U8X8_PIN_NONE); //…

give it an eyeball and as I say it may or may not add to your knowledge base for the subject.
