WiFiCLient example does not work - Pico EVB #8
Description
Hi @GiungKim ,
It looks the WizFI360-Pico-EVB has problems to run the WiFiCLient basic example.
Basically the code is hanging when the client is defined , if I comment the client code like this
/*
WizFi360 example: WebClient
This sketch connects to google website using a WizFi360 module to
perform a simple web search.
*/
#include "WizFi360.h"
// setup according to the device you use
#define WIZFI360_EVB_PICO
// Emulate Serial1 on pins 6/7 if not present
#ifndef HAVE_HWSERIAL1
#include "SoftwareSerial.h"
#if defined(ARDUINO_MEGA_2560)
SoftwareSerial Serial1(6, 7); // RX, TX
#elif defined(WIZFI360_EVB_PICO)
SoftwareSerial Serial2(6, 7); // RX, TX
#endif
#endif
/* Baudrate */
#define SERIAL_BAUDRATE 115200
#if defined(ARDUINO_MEGA_2560)
#define SERIAL1_BAUDRATE 115200
#elif defined(WIZFI360_EVB_PICO)
#define SERIAL2_BAUDRATE 115200
#endif
/* Wi-Fi info */
char ssid[] = "TraceAP"; // your network SSID (name)
char pass[] = "Liberty123"; // your network password
int status = WL_IDLE_STATUS; // the Wifi radio's status
// char server[] = "arduino.tips";
// Initialize the Ethernet client object
// WiFiClient client;
void setup() {
// initialize serial for debugging
Serial.begin(SERIAL_BAUDRATE);
// initialize serial for WizFi360 module
#if defined(ARDUINO_MEGA_2560)
Serial1.begin(SERIAL1_BAUDRATE);
#elif defined(WIZFI360_EVB_PICO)
Serial2.begin(SERIAL2_BAUDRATE);
#endif
// initialize WizFi360 module
#if defined(ARDUINO_MEGA_2560)
WiFi.init(&Serial1);
#elif defined(WIZFI360_EVB_PICO)
WiFi.init(&Serial2);
#endif
// check for the presence of the shield
if (WiFi.status() == WL_NO_SHIELD) {
Serial.println("WiFi shield not present");
// don't continue
while (true);
}
// attempt to connect to WiFi network
while ( status != WL_CONNECTED) {
Serial.print("Attempting to connect to WPA SSID: ");
Serial.println(ssid);
// Connect to WPA/WPA2 network
status = WiFi.begin(ssid, pass);
}
// you're connected now, so print out the data
Serial.println("You're connected to the network");
// printWifiStatus();
printWifiData();
// Serial.println();
// Serial.println("Starting connection to server...");
// // if you get a connection, report back via serial
// if (client.connect(server, 80)) {
// Serial.println("Connected to server");
// // Make a HTTP request
// client.println("GET /asciilogo.txt HTTP/1.1");
// client.println("Host: arduino.tips");
// client.println("Connection: close");
// client.println();
// }
}
void loop() {
printWifiData();
delay(10000);
// if there are incoming bytes available
// from the server, read them and print them
// while (client.available()) {
// char c = client.read();
// Serial.write(c);
// }
// // wait to let all the input command in the serial buffer
// delay(5);
// // if the server's disconnected, stop the client
// if (!client.connected()) {
// Serial.println();
// Serial.println("Disconnecting from server...");
// client.stop();
// // do nothing forevermore
// while (true);
// }
}
void printWifiData() {
// print your WiFi shield's IP address
IPAddress ip = WiFi.localIP();
Serial.print("IP Address: ");
Serial.println(ip);
// print your MAC address
byte mac[6];
WiFi.macAddress(mac);
char buf[20];
sprintf(buf, "%02X:%02X:%02X:%02X:%02X:%02X", mac[5], mac[4], mac[3], mac[2], mac[1], mac[0]);
Serial.print("MAC address: ");
Serial.println(buf);
}
void printWifiStatus() {
// print the SSID of the network you're attached to
Serial.print("SSID: ");
Serial.println(WiFi.SSID());
// print your WiFi shield's IP address
Serial.print("IP Address: ");
IPAddress ip = WiFi.localIP();
Serial.println(ip);
// print the received signal strength
long rssi = WiFi.RSSI();
Serial.print("Signal strength (RSSI):");
Serial.print(rssi);
Serial.println(" dBm");
}
I am able to get the loop print the WiFIData evry 10 seconds, if I uncomment the line
WiFiClient client;
Then the code hangs and loop does not execute further.
How can I debug this?
I have tried to add a try catch thing around the client without any success
void loop() {
try
{
WiFiClient client;
}
catch(const char* e)
{
Serial.println("cannot create WiFiCLient class");
}
while(true)
{
printWifiData();
delay(10000);
}
}
Now the output console for the above program is the same in both cases, it does not complete the call to printWifiData(); in setup and the board get into an error state so I have to manually boot it and add .uf2 file to recover it.
