Whenever
I try to compile either program, in the Arduino IDE (1.8.19), I get the following error.

“In function ‘void setup()’:
ESP-32_and_NEO-6m_GPS-rndtut-v1:9:14: error: invalid conversion from ‘int’ to ‘SerialMode’ [-fpermissive]”

#define RXD2 16
#define TXD2 17
…seems to cause an error.

Hi.
We bought ours from amazon.
Search for “arduino gps antenna u-blox waterproof”

I hope this helps.

Thanks. Your tutorials are always helpful and informative.

One question, though. Can you give me a website ,or google search terms, for the larger antenna?

Thanks. Jim J.

Excellent Tutorial.
This worked very well on my ESP32; but I had a big trouble doing the same thing with the tutorial with ESP8266. The received data wasn’t comming smooth to the ESP8266 and the results varied a lot, so it took a while to solve the problem with my ESP8266. But both sketches in this tutorial worked smoothly, without any problems. Well, I think it is because the ESP32 has two Serial Interfaces, and the ESP8266 only one and it doesn’t work well with the second one.
So, thanks for the tutorial Rui and Sara!

Hi.
The code should run regardless of that message.
Just wait a few minutes until the GPS gathers some data. Make sure it is placed outside or close to a window.

Hi.
I think the issue is because the module hasn’t picked up a signal from the satellites. Make sure you place your GPS module outside and wait for a while.
It may take a few minutes.

Hey,
I am working with an ESP32 (Lolin32) and a NEO 7m GPS module. Unfortunately, I do not get any output for the second code and for the first I only get the series of “-“. I checked that the pins are correct and adjusted the code accordingly. The LED on the GPS Module lights up red continuously.
Did someone run into a similar problem or know a possible solution?

Thanks!
