Arduino IDE 显示 ESP32 Sketch 太大。空间不足如何解决

Question

我为 ESP32 编写了一个小程序，用于在 OLED 显示屏上显示时间、日期和加密货币价格。它还可以选择通过蓝牙串行更改手表相位。它编译成功，没有任何语法错误。但它显示以下错误消息

草图太大；有关提示，请参阅 https://support.arduino.cc/hc/en-us/articles/360013825179 减少它。 Sketch 使用 1508690 字节 (115%) 的程序存储 空间。最大值为 1310720 字节。全局变量使用52728字节 (16%) 的动态内存，为局部变量留下 274952 字节。 最大值为 327680 字节。文本部分超出了板上的可用空间

编译错误：文本部分超出了板上的可用空间

我发现“BluetoothSerial.h”和占用了这么多空间。我该如何解决这个问题

我正在使用 esp32 firebeetle。分区方案选项无法添加更多空间
