esp32小车开发怎么脱离固定WIFI环境

Question

我这里有一个esp32camWIFI小车的代码，但是要依靠家里的固定网络，怎么把它改成手机连接蓝牙，或者是直接把esp32cam当成自带的热点连接，从而可以大范围使用。

#include "esp_camera.h"
#include <WiFi.h>
#include "esp_timer.h"
#include "img_converters.h"
#include "Arduino.h"
#include "fb_gfx.h"
#include "soc/soc.h"             // disable brownout problems
#include "soc/rtc_cntl_reg.h"    // disable brownout problems
#include "esp_http_server.h"

// Replace with your network credentials
const char* ssid = "HUA101";
const char* password = "13492736297992";
