Hi

I've installed the ESP32 support in my Arduino IDE and can compile and run the blink and BLE_Scan examples from the IDE. Both work fine. When I try and compile this project I get an error saying the sketch is too big?

Archiving built core (caching) in: C:\Users[USER]\AppData\Local\Temp\arduino_cache_768145\core\core_espressif_esp32_WeMosBat_FlashFreq_80,UploadSpeed_921600_89e97c72e9bd6fa98e6bdd6fae23ba9b.a Sketch uses 1395266 bytes (106%) of program storage space. Maximum is 1310720 bytes.

Global variables use 93296 bytes (31%) of dynamic memory, leaving 201616 bytes for local variables. Maximum is 294912 bytes. Sketch too big; see http://www.arduino.cc/en/Guide/Troubleshooting#size for tips on reducing it. Error compiling for board "WeMos" WiFi&Bluetooth Battery.

For me the fix was for the board: It seems that the default.csv is wrong for some boards

# Name, Type, SubType, Offset, Size, Flags nvs, data, nvs, 0x9000, 0x5000, otadata, data, ota, 0xe000, 0x2000, app0, app, ota_0, 0x10000, 0x340000, eeprom, data, 0x99, 0x350000, 0x1000, spiffs, data, spiffs, 0x351000, 0xAF000,

and boards.txt to have modified values of .upload.maximum_size=3407872 you have to edit the line that is specific to your board.
