ArduinoWiFiESP32

Arduino nano 33 IOT

今基板に搭載されているESP32を通して、PCとWifi通信を
したいと思っております。

現在、スケッチ例"AdvancedWebServer"にて
簡易的にブラウザからアクセスをしようと思うのですが、
上手くいきません。。
何が問題か教えていただけないでしょうか。。

include "WiFi.h"

char ssid = "your ssid"; // アクセスするssidを設定
char password = "your password"; 　// パスワードを設定
int value = 0;　　　　　　　　　　　　　//　
WiFiServer server(80);　　//　PCからの応答を読み取るためのサーバ定義

void setup()　　//ここから初期化の処理
{
Serial.begin(115200);　//　シリアル・ポートの速度を設定　
Serial.println("start pgm");　//シリアル・モニタにプログラム開始を表示

delay(10);
// We start by connecting to a WiFi network
Serial.println();　//　改行をシリアル・モニタに出力
Serial.println();
Serial.print("Connecting to ");　// シリアル・モニタに接続のメッセージを表示
Serial.println(ssid);　//　接続先としてssidを表示
WiFi.begin(ssid, password);　//　Wi-Fiへの接続処理
while (WiFi.status() != WL_CONNECTED) {　// Wi-Fiと接続されるのを待つ
    delay(500);
Serial.print(".");
}　　　　//　接続され 条件が＝になったらここを抜ける
Serial.println("");
Serial.println("WiFi connected.");　// 接続されたときの見出し
Serial.println("IP address: ");　// ボードのIPアドレス表示の見出し
Serial.println(WiFi.localIP());　//　ボードのIPアドレスを表示
server.begin();　//PCからのLEDのON/OFFの指示を読むためサーバ開始

}

void loop(){

}

@uasi

error: stray '\343' in program はググれば出てくると思いますが、ソースコード中に全角スペースがあるエラーです。半角スペースにしてください。

また error: invalid conversion from 'char' to 'char*' については

char ssid = "your ssid";
char password = "your password";

を setup() の中に移動し、 char* にして

void setup()
{
    char* ssid = "your ssid";
    char* password = "your password"; 
    ...

としてください。
