Finally, I changed cables (once again) and now GPS has a proper power supply (red LED is switched on). Still don't have the coordinates but I am in the room, interior...I think I should go outdoors.

Are you sure you're not using an ESP32 (module) with PSRAM? If so, GPIO 17 is generally unavailable.

Isn't GPIO 17 a UART U2_TXD??

I am using ESP32S (DEVKIT 1).

From the image below I see thta RX, TX (GPIO16 and GPIO 17) are UART2.

Using this code I permanently got the error" G PS not detected. Check wiring" .


#include <HardwareSerial.h>
#include <TinyGPSPlus.h>

HardwareSerial GPSSerial (2);
TinyGPSPlus gps;

void setup()
{
Serial.begin(9600);
GPSSerial.begin ( 9600, SERIAL_8N1, 16, 17 ); // begin GPS hardware serial ...

Hello forum!

I have difficulties with connecting ESP32-3248S035 board with GPS MatekSys ublox SAM-M8Q .
The ESP32-3248S035 is a rather rare board and the documentation is not so good.

I know it is UART, so I need to connect RX with TX and TX with RX, and GND with GND. But I don't know what ...

Problem solved - I have installed Arduino IDE from "Ubuntu Software". Now IDE works good!

Hello forum!

I am trying to verify sample / example code for ESP32 and I got error every time:
