B4R Question Flash Mode Error

[iCAB]

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

Are you sure that it is a ESP32 board?

Hi Erel

This what it says on the back:
Wemos
Wifi & BleTooth R32
Board ESP32
V1.0.0

The chip says: ESP WROOM 32

Are you able to run a program from Arduino IDE?

Hi Erel


According to : https://github.com/espressif/arduino-esp32/blob/master/docs/arduino-ide/boards_manager.md

We are supposed to use the Arduino IDE Board Manager to update the SDK using the Stable Release Link:
https://dl.espressif.com/dl/package_esp32_index.json

for whatever reason the above link doesn't work.
I tried the development link: https://dl.espressif.com/dl/package_esp32_dev_index.json and all seems ok now.

Thanks
