ESP32 thing WiFi connection issues.

Wireless & IoT Wifi

Hello there,

I am having trouble connecting my esp32 thing to WIFI it will not work with any router or even the hot spot on my phone.

if I open the serial port in Auruino ide it get stuck on wifi conecting …

I have run the wifi scanner code it picks up the networks in the area.

The code being implemented is the (Example14_NTRIPServer)

#include <WiFi.h>

#include “secrets.h”

WiFiClient ntripCaster;

#include <Wire.h>

#include <SparkFun_u-blox_GNSS_Arduino_Library.h> //http://librarymanager/All#SparkFun_u-blox_GNSS

SFE_UBLOX_GNSS myGNSS;

//Global Variables

//=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

long lastSentRTCM_ms = 0; //Time of last data pushed to socket

int maxTimeBeforeHangup_ms = 10000; //If we fail to get a complete RTCM frame after 10s, then disconnect from caster

uint32_t serverBytesSent = 0; //Just a running total

long lastReport_ms = 0; //Time of last report of bytes sent

//=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

void setup()

{

Serial.begin(115200); // You may need to increase this for high navigation rates!

while (!Serial)

; //Wait for user to open terminal

Serial.println(F(“SparkFun u-blox Example”));

Wire.begin();

//myGNSS.enableDebugging(); // Uncomment this line to enable debug messages

if (myGNSS.begin() == false) //Connect to the u-blox module using Wire port

{

Serial.println(F(“u-blox GNSS not detected at default I2C address. Please check wiring. Freezing.”));

while (1)

;

}

Serial.print(“Connecting to local WiFi”);

WiFi.begin(ssid, password);

while (WiFi.status() != WL_CONNECTED)

{

delay(500);

Serial.print(“.”);

}

Serial.print("\nWiFi connected with IP: ");

Serial.println(WiFi.localIP());

Serial.print("\nWiFi connected with IP: ");

Serial.println(WiFi.localIP());

(secrets.h) Folder is as follows

//Your WiFi credentials

const char *ssid = “Anthony’s iPhone”;

const char *password = “test”;

//RTK2Go works well and is free

const char casterHost = “caster.emlid.com”;

const uint16_t casterPort = 2101;

const char mountPoint = “XXXXXX”; //The mount point you want to push data to

const char mountPointPW = “XXXXXX”;

Is something missing ?

Thank You!

Try putting <secrets.h> instead of “secrets.h” and see that gets it going…

Also, for the WiFi example https://learn.sparkfun.com/tutorials/es … ample-wifi - does the serial monitor return anything when inputting “0” to make the URL request?

3

unfortunately <secrets.h> did not work returned with no such file or directory. Not sure what you mean by imputing “0”

4

If your referring to the “0” button on the board then nothing occurs.

Try to choose an easier SSID to connect to instead of “Anthony’s iPhone”. Something “iphone”. Sometimes special characters or space are not appreciated

In the sketch print your SSID and password and double-check these are correct.

Thank you Paulvha! Changing the wifi ssid to a name without characters worked! Unfortunately now I can’t get it to connect to emlid. This may be a dumb question but in the serial viewer it has all the connections complete then goes to “Press any key to start serving” I press multiple keys and nothing happens. In the setup guide it shows this normal but I do I need to press something else? Then upon opening Tera viewer I get a bunch of characters and symbols not “total bytes sent to caster” I apologize for so many questions but I am total noob to programming.

Thank You!

press on your keyboard. Normally that works.

The “bunch of symbols” is often the result of incorrect baudrate of the viewer. Needs to be set to 115200, 8,N,1

Thank you paulvha! I had not seen the spot on the of the serial port window to send to the esp32 I was just just pressing keys on the keyboard lol!

Thank you!
