In another thread it is suggested to select ESP32 DEV when developing on Wemos D32 or similar dev boards with ESP32 and OLED display.
Unfortunately, I can't find ESP32 DEV in the list of supported boards.
My b4r is version 3.31 and arduino 1.8.12
Unfortunately, I got an error during compilation. I have both esp32 from expressif and esp8266 library from community installed.
Compiling for esp8266 (wemos d1 mini) ends succesfully.
b4r_main.cpp:77:28: fatal error: ESP8266WiFi.h: No such file or directory
Yes, I've got it properly selected. This is a replica of a Lolin D32 Pro (not the original to spec, unfortunately), but even if I select ESP 32 DEV makes no difference.
Solved. I had a C inline which was interfering with the compilation.
It's running, though I now have some runtime guru meditation, after porting code for 8266 to ESP32.
Thanks.
