B4R Question Flash Mode Error

Hi All

I am using WeMos board to learn B4R tools.

I was able to compile few sample examples ( like temparture sensor ).

I wanted to try the Bluetooth sample as described in this link:
https://www.b4x.com/android/forum/threads/resp32bluetooth-esp32-classic-bluetooth.93257/

So I updated the ESP32 SDK using the Arduino IDE.
Now I started getting the following error: FlashMode: Invalid option for board "esp32"

I opened the board selector and tried the 4 different options listed under FlasMode. All options give the same error.

Any ideas?


Thanks
